These devices are designed to replace multiple traditional microcontroller unit MCU -based system components with one, low-cost single-chip programmable device. PSoC devices include configurable blocks of analog and digital logic, as well as programmable interconnects. This architecture allows you to create customized peripheral configurations that match the requirements of each individual application. Additionally, a fast central processing unit CPU , flash program memory, SRAM data memory, and configurable I/O are included in a range of convenient pinouts and packages. The PSoC architecture, as illustrated in the Logic Block Diagram on page 1, consists of four main areas PSoC core, digital system, analog system, and system resources. Configurable global busing allows all of the device resources to be combined into a complete custom system. The PSoC CY8C29x66 family can have up to five I/O ports that connect to the global digital and analog interconnects, providing access to 8 digital blocks and 12 analog blocks. PSoC Core The PSoC core is a powerful engine that supports a rich feature set. The core includes a CPU, memory, clocks, and configurable GPIOs. The M8C CPU core is a powerful processor with speeds up to 24 MHz, providing a 4 million instructions per second MIPS 8-bit Harvard-architecture microprocessor. The CPU uses an interrupt controller with 17 vectors, to simplify programming of real-time embedded events. Program execution is timed and protected using the included sleep and watchdog timers WDT . Memory uses 16 KB of flash for program storage, 256 bytes of SRAM for data storage, and up to 2 KB of EEPROM emulated using the flash. Program flash uses four protection levels on blocks of 64 bytes, allowing customized software information protection IP . The PSoC device incorporates flexible internal clock generators, including a 24 MHz internal main oscillator IMO accurate to over temperature and voltage. The 24 MHz IMO can also be doubled to 48 MHz for use by the digital system. A low-power 32 kHz internal low speed oscillator ILO is provided for the sleep timer and WDT. If crystal accuracy is desired, the kHz external crystal oscillator ECO is available for use as a real-time clock RTC and can optionally generate a crystal-accurate 24 MHz system clock using a PLL. The clocks, together with programmable clock dividers as a system resource , provide the flexibility to integrate almost any timing requirement into the PSoC device. PSoC GPIOs provide connection to the CPU, and digital and analog resources of the device. Each pin’s drive mode may be selected from eight options, allowing great flexibility in external interfacing. Every pin also has the capability to generate a system interrupt on high level, low level, and change from last read. Digital System The digital system is composed of 16 digital PSoC blocks. Each block is an 8-bit resource that can be used alone or combined with other blocks to form 8-, 16-, 24-, and 32-bit peripherals, which are called user modules.

Here you can find various application designs that include firmware and hardware design files that enable you to complete your designs quickly. Technical Support Technical support including a searchable Knowledge Base articles and technical forums is also available online. If you cannot find an answer to your question, call our Technical Support hotline at PSoC Designer Software Subsystems Design Entry In the chip-level view, choose a base device to work with. Then select different onboard analog and digital components that use the PSoC blocks, which are called user modules. Examples of user modules are analog-to-digital converters ADCs , digital-to-analog converters DACs , amplifiers, and filters. Configure the user modules for your chosen application and connect them to each other and to the proper pins. Then generate your project. This prepopulates your project with APIs and libraries that you can use to program your application. The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration makes it possible to change configurations at run time. In essence, this allows you to use more than 100 percent of PSoC's resources for an application. Code Generation Tools The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. You can develop your design in C, assembly, or a combination of the two. Assemblers. The assemblers allow you to merge assembly code seamlessly with C code. Link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. C Language Compilers. C language compilers are available that support the PSoC family of devices. The products allow you to create complete C programs for the PSoC family devices. The optimizing C compilers provide all of the features of C, tailored to the PSoC architecture. They come complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. Page 6 of 50 [+] Feedback CY8C29466, CY8C29566 CY8C29666, CY8C29866 Debugger PSoC Designer has a debug environment that provides hardware in-circuit emulation, allowing you to test the program in a physical system while providing an internal view of the PSoC device. Debugger commands allow you to read and program and read and write data memory, and read and write I/O registers. You can read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows you to create a trace buffer of registers and memory locations of interest. Online Help System The online help system displays online, context-sensitive help. Designed for procedural and quick reference, each functional subsystem has its own context-sensitive help. This system also provides tutorials and links to FAQs and an Online Support Forum to aid the designer. Designing with PSoC Designer The development process for the device differs from that of a traditional fixed function microprocessor. The configurable analog and digital hardware blocks give the PSoC architecture a unique flexibility that pays dividends in managing specification change during development and by lowering inventory costs. These configurable resources, called PSoC Blocks, have the ability to implement a wide variety of user-selectable functions. The PSoC development process is summarized in four steps: Select User Modules. Configure user modules. Organize and connect. Generate, verify, and debug. Select User Modules PSoC Designer provides a library of prebuilt, pretested hardware peripheral components called “user modules.” User modules make selecting and implementing peripheral devices, both analog and digital, simple. Configure User Modules Each user module that you select establishes the basic register settings that implement the selected function. They also provide parameters and properties that allow you to tailor their precise configuration to your particular application. For example, a pulse width modulator PWM User Module configures one or more digital PSoC blocks, one for each 8 bits of resolution. The user module parameters permit you to establish the pulse width and duty cycle. Configure the parameters and properties to correspond to your chosen application. Enter values directly or by selecting values from drop-down menus. All the user modules are documented in datasheets that may be viewed directly in PSoC Designer or on the Cypress website. These user module datasheets explain the internal operation of the user module and provide performance specifications. Each datasheet describes the use of each user module parameter, and other information you may need to successfully implement your design. In-Circuit Emulator A low-cost, high-functionality In-Circuit Emulator ICE is available for development support. This hardware can program single devices. The emulator consists of a base unit that connects to the PC using a USB port. The base unit is universal and operates with all PSoC devices. Emulation pods for each device family are available separately. The emulation pod takes the place of the PSoC device in the target board and performs full-speed 24 MHz operation. Organize and Connect You build signal chains at the chip level by interconnecting user modules to each other and the I/O pins. You perform the selection, configuration, and routing so that you have complete control over all on-chip resources. Notes Flex-Pod kit includes a practice flex-pod and a practice PCB, in addition to two flex-pods. Foot kit includes surface mount feet that can be soldered to the target PCB. Programming adapter converts non-DIP package to DIP footprint.

Every pin also has the capability to generate a system interrupt on high level, low level, and change from last read.

Digital System

The digital system is composed of 16 digital PSoC blocks. Each block is an 8-bit resource that can be used alone or combined with other blocks to form 8-, 16-, 24-, and 32-bit peripherals, which are called user modules.

PSoC Designer Software Subsystems

Design Entry In the chip-level view, choose a base device to work with. Then select different onboard analog and digital components that use the PSoC blocks, which are called user modules. Examples of user modules are analog-to-digital converters ADCs , digital-to-analog converters DACs , amplifiers, and filters. Configure the user modules for your chosen application and connect them to each other and to the proper pins. Then generate your project. This prepopulates your project with APIs and libraries that you can use to program your application. The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration makes it possible to change configurations at run time. In essence, this allows you to use more than 100 percent of PSoC's resources for an application.

Code Generation Tools The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. You can develop your design in C, assembly, or a combination of the two. Assemblers. The assemblers allow you to merge assembly code seamlessly with C code. Link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. C Language Compilers. C language compilers are available that support the PSoC family of devices. The products allow you to create complete C programs for the PSoC family devices. The optimizing C compilers provide all of the features of C, tailored to the PSoC architecture. They come complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality.

Debugger

PSoC Designer has a debug environment that provides hardware in-circuit emulation, allowing you to test the program in a physical system while providing an internal view of the PSoC device. Debugger commands allow you to read and program and read and write data memory, and read and write I/O registers. You can read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows you to create a trace buffer of registers and memory locations of interest.

Online Help System

The online help system displays online, context-sensitive help. Designed for procedural and quick reference, each functional subsystem has its own context-sensitive help. This system also provides tutorials and links to FAQs and an Online Support Forum to aid the designer.

Designing with PSoC Designer

The development process for the device differs from that of a traditional fixed function microprocessor. The configurable analog and digital hardware blocks give the PSoC architecture a unique flexibility that pays dividends in managing specification change during development and by lowering inventory costs. These configurable resources, called PSoC Blocks, have the ability to implement a wide variety of user-selectable functions. The PSoC development process is summarized in four steps:

Select User Modules.

Configure user modules.

Organize and connect.

Generate, verify, and debug.

Select User Modules

PSoC Designer provides a library of prebuilt, pretested hardware peripheral components called “user modules.” User modules make selecting and implementing peripheral devices, both analog and digital, simple.

Configure User Modules

Each user module that you select establishes the basic register settings that implement the selected function. They also provide parameters and properties that allow you to tailor their precise configuration to your particular application. For example, a pulse width modulator PWM User Module configures one or more digital PSoC blocks, one for each 8 bits of resolution. The user module parameters permit you to establish the pulse width and duty cycle. Configure the parameters and properties to correspond to your chosen application. Enter values directly or by selecting values from drop-down menus. All the user modules are documented in datasheets that may be viewed directly in PSoC Designer or on the Cypress website. These user module datasheets explain the internal operation of the user module and provide performance specifications. Each datasheet describes the use of each user module parameter, and other information you may need to successfully implement your design.

In-Circuit Emulator A low-cost, high-functionality In-Circuit Emulator ICE is available for development support. This hardware can program single devices. The emulator consists of a base unit that connects to the PC using a USB port. The base unit is universal and operates with all PSoC devices. Emulation pods for each device family are available separately. The emulation pod takes the place of the PSoC device in the target board and performs full-speed 24 MHz operation.

Organize and Connect You build signal chains at the chip level by interconnecting user modules to each other and the I/O pins. You perform the selection, configuration, and routing so that you have complete control over all on-chip resources.
Notes Flex-Pod kit includes a practice flex-pod and a practice PCB, in addition to two flex-pods. Foot kit includes surface mount feet that can be soldered to the target PCB. Programming adapter converts non-DIP package to DIP footprint. Specific details and ordering information for each of the adapters can be found at
