1 / 5 page 1/5 STA2051 VESPUCCI September 2004 This is preliminary information on a new product now in development. Details are subject to change without notice. 1 FEATURES ■ ARM7TDMI 16/32 bit RISC CPU based host microcontroller. ■ Complete Embedded Memory System: – FLASH 256K bytes + 16K bytes (100K eras- ing/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. ■ -40°C to 85°C 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 ex- ternal 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 DATA BRIEF 32-BIT SINGLE CHIP BASEBAND CONTROLLER FOR GPS AND TELEMATIC APPLICATIONS Rev. 1 Figure 1.
