1 / 4 page DATA BRIEF For further information contact your local STMicroelectronics sales office. January 2006 DocRev1 1/4 4 STA2051GO Single Chip GPS Controller Features ■ Suitable for hand held accessories, portable and personal navigation systems ■ ARM7TDMI 16/32 bit RISC CPU based host microcontroller running at a frequency up to 32 MHz. ■ Complete Embedded Memory System: – FLASH 256K bytes + 16K bytes (100K erasing/programming cycles) – RAM 64K bytes. ■ 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. ■ Power Supply: – 3.0V to 3.6V operating supply range for Input/Output periphery – 3.0V to 3.6V operating supply range for A/D Converter reference – 1.8V operating supply range for core supply provided by internal Voltage Regulator with external stabilization capacitor. ■ 32 programmable General Purpose I/O multiplexed with peripheral functions, each pin programmable independently as digital input or digital output. ■ 4 Channels A/D for low frequency signal monitoring (temperature, battery....) ■ Real time clock module with 32 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. ■ Four Serial Communication Interfaces (UART) allow full duplex, asynchronous, communications with external devices, independently programmable TX and RX baud rates up to 625K baud. ■ One Serial Peripheral Interfaces (SPI) allow full duplex, synchronous communications with external devices, master or slave operation, max baud rate: 5.5Mb/s. One SPI may be used as Multimedia Card interface. ■ One I 2C Interfaces provide multi-master and slave functions, support normal and fast I2C mode (400 KHz), 7/10 bit addressing modes. ■ Wake-up unit allows exiting from powerdown modes by detection of an event on one external pins or on internal Real Time Clock alarm. ■ -40°C to 85°C operating temperature range (guaranteed by correlation).
