The processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. The AT91FR40162 ARM microcontroller features 2 Mbits of on-chip SRAM and 2 Mbytes of Flash memory in a single compact 121-ball BGA package. Its high level of integration and very small footprint make the device ideal for space-constrained applications. The high-speed on-chip SRAM enables a performance of up to 74 MIPs in typical conditions with significant power reduction and EMC improvement over an external SRAM implementation. The Flash memory may be programmed via the JTAG/ICE interface or the factoryprogrammed Flash Uploader using a single device supply, making the AT91FR40162 suitable for in-system programmable applications. 2632D-ATARM-15-Sep-05 Pin Configuration Figure AT91FR40162 Pinout for 121-ball BGA Package Top View A1 Corner 10 11 P21/TXD1 NTRI P15 RXD0 P11 IRQ2 VDDCORE P8 TIOB2 P6 TCLK2 P2 TIOB0 P22 RXD1 P20 SCK1 P12 FIQ P10 IRQ1 VDDIO P7 TIOA2 P4 TIOA1 P1 TIOA0 VDDIO NUB P14 NBUSY P9 NWR1 TXD0 IRQ0 TIOB1 TCLK1 P0 TCLK0 Product overview Ordering information Packaging information Soldering profile Detailed description of Flash memory Document Title ARM7TDMI Thumb Datasheet AT91x40 Series Datasheet AT91R40008 Electrical Characteristics Datasheet AT49BV/LV1604A/1614A T 2-Mbyte 1M x 16/2M x 8 3volt Only Flash Memory Datasheet AT91FR40162 Datasheet this document AT49BV/LV1604A/1614A T 2-Mbyte 1M x 16/2M x 8 3volt Only Flash Memory Datasheet 8 AT91FR40162 AT91FR40162 Product Overview Power Supply The AT91FR40162 device has two types of power supply pins: • VDDCORE pins that power the chip core i.e., the AT91R40008 with its embedded SRAM and peripherals • VDDIO pins that power the AT91R40008 I/O lines and the Flash memory An independent I/O supply allows a flexible adaptation to external component signal levels. Input/Output Considerations The AT91FR40162 I/O pads accept voltage levels up to the VDDIO power supply limit. After the reset, the microcontroller peripheral I/Os are initialized as inputs to provide the user with maximum flexibility. It is recommended that in any application phase, the inputs to the microcontroller be held at valid logic levels to minimize the power consumption. Master Clock The AT91FR40162 has a fully static design and works on the Master Clock MCK , provided on the MCKI pin from an external source. The Master Clock is also provided as an output of the device on the pin MCKO, which is multiplexed with a general purpose I/O line. While NRST is active, and after the reset, the MCKO is valid and outputs an image of the MCK signal. The PIO Controller must be programmed to use this pin as standard I/O line. Reset Reset restores the default states of the user interface registers defined in the user interface of each peripheral , and forces the ARM7TDMI to perform the next instruction fetch from address zero. Except for the program counter the ARM7TDMI registers do not have defined reset states. NRST Pin NRST is active low-level input. It is asserted asynchronously, but exit from reset is synchronized internally to the MCK. The signal presented on MCKI must be active within the specification for a minimum of 10 clock cycles up to the rising edge of NRST to ensure correct operation. The first processor fetch occurs 80 clock cycles after the rising edge of NRST. Watchdog Reset The watchdog can be programmed to generate an internal reset. In this case, the reset has the same effect as the NRST pin assertion, but the pins BMS and NTRI are not sampled. Boot Mode and Tri-state Mode are not updated. If the NRST pin is asserted and the watchdog triggers the internal reset, the NRST pin has priority. Emulation Functions Tri-state Mode The AT91FR40162 microcontroller provides a tri-state mode, which is used for debug purposes. This enables the connection of an emulator probe to an application board without having to desolder the device from the target board. In tri-state mode, all the output pin drivers of the AT91R40008 microcontroller are disabled. In tri-state mode, direct access to the Flash via external pins is provided. This enables production Flash programming using classical Flash programmers prior to board mounting. To enter tri-state mode, the NTRI pin must be held low during the last 10 clock cycles before the rising edge of NRST. For normal operation, the NTRI pin must be held high during reset by a resistor of up to 400 NTRI is multiplexed with I/O line P21 and USART1 serial data transmit line TXD1. JTAG/ICE Debug ARM-standard embedded In-circuit Emulation is supported via the JTAG/ICE port. The pins TDI, TDO, TCK and TMS are dedicated to this debug function and can be connected to a host computer via the external ICE interface. In ICE Debug Mode, the ARM7TDMI core responds with a non-JTAG chip ID that identifies the microcontroller. This is not fully IEEE1149.1 compliant. Memory Controller The ARM7TDMI processor address space is 4G bytes. The memory controller decodes the internal 32-bit address bus and defines three address spaces: • Internal memories in the four lowest megabytes • Middle space reserved for the external devices memory or peripherals controlled by the EBI • Internal peripherals in the four highest megabytes In any of these address spaces, the ARM7TDMI operates in little-endian mode only. Internal Memories The AT91FR40162 microcontroller integrates 256K bytes of internal SRAM. It is 32 bits wide and single-clock cycle accessible. Byte 8-bit , half-word 16-bit and word 32-bit accesses are supported and are executed within one cycle. Fetching either Thumb or ARM instructions is supported, and internal memory can store two times as many Thumb instructions as ARM instructions. The SRAM is mapped at address 0x0 after the Remap command , allowing ARM7TDMI exception vectors between 0x0 and 0x20 to be modified by the software. Placing the SRAM on-chip and using the 32-bit data bus bandwidth maximizes the microcontroller performance and minimizes system power consumption. The 32-bit bus increases the effectiveness of the use of the ARM instruction set and the processing of data that is wider than 16 bits, thus making optimal use of the ARM7TDMI advanced performance. Being able to dynamically update application software in the 256-Kbyte SRAM adds an extra dimension to the AT91FR40162. The AT91FR40162 also integrates a 2-Mbyte Flash memory that is accessed via the External Bus Interface. All data, address and control lines, except for the Chip Select signal, are connected within the device. 10 AT91FR40162 AT91FR40162 Ordering Information Table Ordering Information Ordering Code AT91FR40162-CI Package BGA 121 AT91FR40162 Temperature Operating Range Industrial -40° C to 85° C Packaging Information Figure AT91FR40162 Package Table Symbol Thermal Resistance Data Parameter Junction-to-ambient thermal resistance Junction-to-case thermal resistance Condition Still Air Package 121-BGA 121-BGA Table 194 Device and 121-ball BGA Package Maximum Weight mg Table 121-ball BGA Package Characteristics Ball diameter Ball land Solder mask opening Plating material Solder ball material Moisture Sensitivity Level 18 AT91FR40162 mm ± mm ± mm Copper Sn/Pb 3 Units ° C/W AT91FR40162 Soldering Profile Table 10-1 gives the recommended soldering profile from J-STD-20.
