简  介:STA2051 VESPUCCI 32-BIT SINGLE CHIP BASEBAND CONTROLLER FOR GPS AND TELEMATIC APPLICATIONS DATA BRIEF 1 ■ ■ 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. -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 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 function……
