MICROPROCESSOR CORE MODULE DIGI RABBITCORE RCM3900 SERIES Combines Fast Ethernet, extended temperature and mass storage to bring versatility to embedded design The RabbitCore RCM3900 series of core modules has fast The microSD Card can be hot-swapped to transfer data program execution SRAM and data SRAM, Flash memory quickly using a standardized file system that can be read and the circuitry necessary for reset and management of directly from the RCM3900 module, or removed and read battery backup for its internal real-time clock and data SRAM. using a microSD card reader. Two 34-pin headers bring out the Rabbit 3000s I/O bus lines, parallel ports and serial ports. The RCM3900 modules mass storage can use the Dynamic C software FAT file system software component to store data and use the same directory file structure commonly used on PCs. BENEFITS APPLICATION EXAMPLE Rabbit 3000 microprocessor at 44 MHz Extended operating temperature range: -20 C to +80 C 10/100Base-T Ethernet DATA PC Up to 1 GB microSD hot-swappable storage Ethernet Lower-risk design of embedded systems RAILWAY SIGNALING SYSTEM applications Software debugging directly on target hardware Train Signal Control Box RABBITCORE RCM3900 RELATED PRODUCTS Serial Track Pressure Sensor RabbitCore RabbitCore RabbitCore Rabbit MiniCore Dynamic C RCM4300 RCM3209 RCM3000 RCM6700 Series Series Series SeriesSPECIFICATIONS RCM3900 RCM3910 FEATURES MICROPROCESSOR Rabbit 3000 at 44 MHz Spectrum spreader for reduced EMI (radiated emissions) EMI REDUCTION 10/100Base-T, RJ-45, 3 LEDs ETHERNET PORT 512K program (fast SRAM) + 512K data SRAM FLASH MEMORY (PROGRAM) 512K MEMORY (DATA STORAGE) 32 MB (fixed NAND flash) + 128 MB 1 GB microSD Card 128 MB 1 GB microSD Card LINK/ACT (link/activity) FDX/COL (full-duplex/ collisions) LED INDICATORS SPEED (on for 100Base-T Ethernet connection) CE/BSY (NAND flash enabled/user programable.
