CXD2931R  
1 chip GPS LSI  
Description  
144 pin LQFP (Plastic)  
The CXD2931R 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.
