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.
