GENERAL DESCRIPTION
The SAA1575HL is an integrated circuit which implements a complete baseband function for Global Positioning System (GPS) receivers. It combines a 16-bit Philips 80C51XA microcontroller, 8 GPS channel correlators and related peripherals in a single IC. Users can implement a complete GPS receiver using only the SAA1575HL, the UAA1570HL front-end Philips IC (or similar), external memory and a few discrete components.
FEATURES
? Single-chip GPS baseband solution with built-in 16-bit microcontroller
? All digital, 0.5 micron CMOS technology
? Single power supply with full 3 V operation
? Separate I/O power supply pins for operation with 3 or 5 V external devices
? Up to 30 MHz system clock from on-chip crystal oscillator or external clock input
? 2 kbytes words internal data memory for fast execution
? External bus for up to 512 kbytes words data memory and 512 kbytes words program memory
? Programmable external bus timing to match external memory speed
? Chip selection outputs to reduce glue logic requirements
? Reset controller for power-down detection and servicing
? 8 GPS channel correlators driven by firmware for flexible GPS correlation algorithms
? 1 second pulse output of GPS time
? 2-bit digital IF GPS signal input synchronized to external sample clock
? 2 fully duplex UARTs for communication with host system processor and other devices
? Real-time clock with 32.768 kHz crystal and supply for low power timekeeping
? Watchdog timer
? Power-down modes under firmware control
? 100-pin LQFP package
? 50 mA supply current (typ.) when 8 GPS channels in track (approximate).
