FEATURES
ARM7TDMI 16/32 bit RISC CPU based host microcontroller. Complete Embedded Memory System: - FLASH 256K bytes + 16K bytes (100K erasing/programming cycles) - RAM 64K bytes. External memory interface provides glueless support for up to four banks of external SRAM, FLASH, ROM. 12 channel GPS correlation DSP: - no TCXO required - RTCA-SC159 / WAAS / EGNOS support GPS performance - accuracy: stand alone <30m; differential <1m; surveying <1cm - time to first fix: autonomous start 90s; cold start 45s; warm start 7s; obscuration 1s. CMOS M8T (0.18 um) technology. -40C to 85C operating temperature range. 144-pin TQFP144 package or 64-pin TQFP64 package Power Supply: - 2.7V to 3.6V operating supply range for Input/ Output periphery - 3 V to 3.6V operating supply range for A/ D Converter reference - 1.8V operating supply range for core supply provided either by internal Voltage Regulator with external stabilization capacitor, or by external supply for higher power efficiency. 0-66MHz internal clock frequency managed by a Reset and Clock Control Unit; the unitisable to provide low power modes (WAIT, SLOW, STOP, STANDBY) and to generate the internal clock from the external reference through integrated PLL. 48 programmable General Purpose I/O, each pin programmable independently as digital input or digital output; 40 (30 in TQFP64) are multiplexed with peripheral functions; 16 can generate an interrupt on input level/transition. Real time clock module with 3 2 KHz low power oscillator and separate power supply to continue running during stand-by mode.

16-bit Watchdog Timer with 8 bits prescaler for system reliability and integrity. CAN module compliant with the CAN specification V2.0 part B (active). The bit rate can be programmed up to 1 MBaud. Four16-bit programmable Timers with 7 bit prescaler, up to two input capture/output compare, one pulse counter function, one PWM channel with selectable frequency each. 4 channels 12-bit sigma-delta Analog to Digital Converter, single channel or multi channel conversion modes, single-shotor continuous conversion modes, sample rate1KHz (4 KHz when single channel), conversion range 0-2.5V. Three Serial Communication Interfaces (UART) allow full duplex, asynchronous, communications with external devices, independently programmable TX and RX baud rates up to 625K baud. One UART adapted to suit Smart Card interface needs, for asynchronous SC as defined by ISO 7816-3; it includes SC clock generation. Two Serial Peripheral Interfaces (SPI) allow full duplex, synchronous communications with external devices, master or slave operation, max baud rate: 8Mb/s. One SPI may be used as Multimedia Card interface. Two I2C Interfaces provide multi-master and slave functions, support normal and fast I2C mode (400KHz), 7/10 bit addressing modes. One I2C Interface is multiplexed with one SPI, so either 2xSPI+1xI2C or 1xSPI+2xI2C may be
