Product specification
Global Positioning System (GPS)
baseband processor
SAA1575HL
The GPS firmware is located in off-chip program memory. It processes the GPS signals from up to 8 satellites and
generates GPS information that can be output to the host processor through one of the two serial ports. Much of
hardware configuration of the SAA1575HL can be controlled by the firmware and so details such as the external bus
timing may change between firmware revisions. For the purpose of this document, the standard Philips firmware has
been assumed (release HD00).
