CXD2931R
1 chip GPS LSI
Description 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. Features • 16-channel GPS receiver capable of simultaneously receiving 16 satellites • Supports differential GPS — Comforms to RTCM SC-104 Ver. 2.1 — Supports DARC • All-in-view measurement • 2-satellite measurement • Timer supporting GPS time • High performance 32-bit RISC CPU • 256K-byte program ROM • 36K-byte RAM • 3-channel UART — Baud rate generator — Supports 1.2K, 2.4K, 4.8K, 9.6K, 19.2K and 38.
