Sony Semiconductor 

1 chip GPS LSI

CXD2931R-9/GA-9

Description

The CXD2931R-9/GA-9 is a dedicated LSI for the

GPS (Global Positioning System) satellite-based

position measurement system.

This LSI contains a 32-bit RISC CPU, 2M-bit MASK

ROM, RAM, UART, timer, and others.

This LSI, used together with the RF LSI (CXA1951AQ),

enables the configuration of a 2-chip system capable

of measuring its position anywhere on the globe.
