| STA2051GO Single Chip GPS Controller DATA BRIEF 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. TQFP64 (10 x 10 x 1.4mm) 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 I2C 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. -40C to 85C operating temperature range (guaranteed by correlation).
