2 RabbitCore RCM3365/RCM33751.1 RCM3365 and RCM3375 Features• Small size: 1.85" x 2.73" x 0.86"(47 mm x 69 mm x 22 mm)• Microprocessor: Rabbit 3000 running at 44.2 MHz• 52 parallel 5 V tolerant I/O lines: 44 configurable for I/O, 4 fixed inputs, 4 fixed outputs• Three additional digital inputs, two additional digital outputs• External reset• Alternate I/O bus can be configured for 8 data lines and 6 address lines (shared withparallel I/O lines), plus I/O read/write• Ten 8-bit timers (six cascadable) and one 10-bit timer with two match registers• 512K flash memory, 512K program execution SRAM, 512K data SRAM• Fixed and hot-swappable mass-storage flash-memory options, which may be used withthe standardized directory structure supported by the Dynamic C FAT File Systemmodule.• Real-time clock• Watchdog supervisor• Provision for customer-supplied backup battery via connections on header J4• 10-bit free-running PWM counter and four pulse-width registers• Two-channel Input Capture (shared with parallel I/O ports) can be used to time inputsignals from various port pins• Two-channel Quadrature Decoder accepts inputs from external incremental encodermodules• Five or six 3.3 V CMOS-compatible serial ports with a maximum asynchronous baudrate of 5.525 Mbps . Three ports are configurable as a clocked serial port (SPI), and twoports are configurable as SDLC/HDLC serial ports (shared with parallel I/O ports).• Supports 1.15 Mbps IrDA transceiver• Supports Dynamic C RabbitSys, which supports Ethernet access for remote applicationupdates, and remote monitoring and control of a RabbitSys-enabled RCM3365The RCM3900/RCM3910 and RCM3365/RCM3375 RabbitCore modules are similar tothe RCM3305/RCM3315 and RCM3309/RCM3319, but they use fixed NAND or remov-able media for their mass-storage memories instead of the fixed serial flash options of theRCM3305/RCM3315 and the RCM3309/RCM3319.
