CXD2932AR-2
GPS Base Band LSI
Description
The CXD2932AR-2 is a dedicated LSI for the GPS
(Global Positioning System) satellite-based position
measurement system.
This LSI contains a 32-bit RISC CPU, satellite
tracking circuit, 2M-bit mask ROM, RAM, UART,
interval timer, and others.
This LSI, used together with the RF LSI, enables the
configuration of a 2-chip system capable of measuring
its position anywhere on the globe.
