The SAA1575HL is a Global Positioning System (GPS) baseband processor with various functions and features.
The SAA1575HL is an integrated circuit that implements a complete baseband function for GPS receivers. It combines a 16-bit Philips 80C51XA microcontroller, eight GPS channel correlators, and related peripherals in a single IC to allow users to implement a complete GPS receiver with minimal external components.
The device operates using all-digital 0.5 micron CMOS technology with a single power supply supporting full 3 V operation. It includes features such as up to 30 MHz system clock speed, 2 kbytes of internal data memory, an external bus for up to 512 kbytes of program and data memory, and two fully duplex UARTs for communication.
