A TrueTouch device includes the configurable TrueTouch block, configurable analog and digital logic, programmable interconnect, and an 8-bit CPU to run custom firmware. This architecture enables the user to create flexible, customized touchscreen configurations to match the requirements of each individual touchscreen application. Various configurations of Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts. The TrueTouch architecture is comprised of four main areas the Core, Digital System, the TrueTouch Analog System, and System Resources including a full speed USB port. Configurable global busing allows all the device resources to be combined into a complete custom touchscreen system. The CY8CTMA120 device can have up to seven IO ports that connect to the global digital and analog interconnects, providing access to four digital blocks and six analog blocks. Implementation of touchscreen application allows additional digital and analog resources to be used, depending on the touchscreen design. The CY8CTMA120 is offered in a 56-pin QFN package with up to 48 general purpose IO GPIO , and support of up to 37 X/Y sensors. When designing touchscreen applications, refer to the UM data sheet for performance requirements to meet and detailed design process explanation. The TrueTouch Core The core includes a CPU, memory, clocks, and configurable GPIO General Purpose IO . The M8C CPU core is a powerful processor with speeds up to 24 MHz, providing a four MIPS 8-bit Harvard architecture microprocessor. The CPU uses an interrupt controller with up to 20 vectors, to simplify programming of real time embedded events. Program execution is timed and protected using the included Sleep and Watch Dog Timers WDT . Memory encompasses 16K of Flash for program storage, 1K of SRAM for data storage, and up to 2K of EEPROM emulated using the Flash. Program Flash uses four protection levels on blocks of 64 bytes, allowing customized software IP protection. The TrueTouch device incorporates flexible internal clock generators, including a 24 MHz IMO Internal Main Oscillator accurate to 8% 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 ILO Internal Low speed Oscillator is provided for the sleep timer and WDT. The clocks, together with programmable clock dividers as a System Resource , provide the flexibility to integrate almost any timing requirement into the TrueTouch device. In USB systems, the IMO self-tunes to ± accuracy for USB communication. The GPIOs provide connection to the CPU, digital and analog resources of the device. Each pin’s drive mode may be selected from eight options, allowing great flexibility in external inter- facing. Every pin is also capable of generating a system interrupt on high level, low level, and change from last read. The Digital System The Digital System is composed of four digital resources. Each block is an 8-bit resource that is used alone or combined with other blocks to form 8, 16, 24, and 32-bit peripherals, which are called user module references.
