| www..com STA2051 VESPUCCI 32-BIT SINGLE CHIP BASEBAND CONTROLLER FOR GPS AND TELEMATIC APPLICATIONS DATA BRIEF 1 FEATURES Figure 1. Packages ARM7TDMI 16/32 bit RISC CPU based host microcontroller. Complete Embedded Memory System: - FLASH 256K bytes + 16K bytes (100K erasTQFP64 TQFP144 ing/programming cycles) - RAM 64K bytes. Table 1. Order Codes External memory interface provides glueless Part Number Package support for up to four banks of external SRAM, STA2051 TQFP64 FLASH, ROM. 12 channel GPS correlation DSP: - no TCXO STA2051E TQFP144 required - RTCA-SC159 / WAAS / EGNOS support 16-bit Watchdog Timer with 8 bits prescaler for GPS performance system reliability and integrity. - accuracy: stand alone <30m; differential CAN module compliant with the CAN <1m; surveying <1cm specification V2.0 part B (active). The bit rate - time to first fix: autonomous start 90s; cold can be programmed up to 1 MBaud. start 45s; warm start 7s; obscuration 1s. Four16-bit programmable Timers with 7 bit CMOS M8T (0.18 um) technology. .com prescaler, up to two input capture/output DataShee -40C to 85C operating temperature range. compare, one pulse counter function, one PWM 144-pin TQFP144 package or 64-pin TQFP64 channel with selectable frequency each. package 4 channels 12-bit sigma-delta Analog to Digital Power Supply: Converter, single channel or multi channel - 2.7V to 3.6V operating supply range for Input/ conversion modes, single-shotor continuous Output periphery conversion modes, sample rate1KHz (4 KHz when single channel), conversion range 0-2.5V. - 3 V to 3.6V operating supply range for A/ D Converter reference Three Serial Communication Interfaces (UART) allow full duplex, asynchronous, - 1.8V operating supply range for core supply communications with external devices, provided either by internal Voltage Regulator independently programmable TX and RX baud with external stabilization capacitor, or by exrates up to 625K baud. ternal supply for higher power efficiency. One UART adapted to suit Smart Card interface 0-66MHz internal clock frequency managed by needs, for asynchronous SC as defined by ISO a Reset and Clock Control Unit; the unitisable to 7816-3; it includes SC clock generation. provide low power modes (WAIT, SLOW, STOP, STANDBY) and to generate the internal Two Serial Peripheral Interfaces (SPI) allow full clock from the external reference through duplex, synchronous communications with integrated PLL. external devices, master or slave operation, max baud rate: 8Mb/s. One SPI may be used as 48 programmable General Purpose I/O, each Multimedia Card interface. pin programmable independently as digital input 2 or digital output; 40 (30 in TQFP64) are Two I C Interfaces provide multi-master and multiplexed with peripheral functions; 16 can slave functions, support normal and fast I2C generate an interrupt on input level/transition. mode (400KHz), 7/10 bit addressing modes. Real time clock module with 3 2 KHz low power One I2C Interface is multiplexed with one SPI, oscillator and separate power supply to so either 2xSPI+1xI2C or 1xSPI+2xI2C may be continue running during stand-by mode. .com September 2004 This is preliminary information on a new product now in development.
