1. INTRODUCTION & OVERVIEW
The RabbitCore RCM2300 is a very small advanced core mod-
ule that incorporates the powerful Rabbit 2000
™
microproces-
sor, flash memory, static RAM, and digital I/O ports, all on a
PCB that is just 1.15" × 1.60" (29.2 mm × 40.6 mm).
1.1 RCM2300 Description
The RCM2300 is a very small core module that packs the processing power of a Rabbit
2000
™
microprocessor into 1.84 square inches (11.9 cm
2
). Two 26-pin headers bring out
the Rabbit 2000 I/O bus lines, address lines, data lines, parallel ports, and serial ports.
The RCM2300 receives its +5 V power from the user board on which it is mounted. The
RCM2300 can interface with all kinds of CMOS-compatible digital devices through the
user board.
The RCM2300 takes full advantage of the following Rabbit 2000 and other built-in features:
• fast, efficient instruction set.
• five 8-bit timers cascadable in pairs, one 10-bit timer with 2 match registers that each
have an interrupt.
• watchdog timer.
• 57 I/O (including general-purpose I/O, address lines, data lines, and control lines on
headers, and 11 I/O on through-hole connectors).
• 256K of nonvolatile flash memory to store applications written for the RCM2300.
• 128K of battery-backable SRAM.
• fast 22.1 MHz clock speed.
• provision for onboard backup battery.
• four serial ports.
Another RabbitCore module can be used to reprogram an RCM2300. This reprogramming
(and debugging) can be done via the Internet using Z-World’s RabbitLink network pro-
gramming gateway or with Ethernet-equipped RabbitCore modules using Dynamic C’s
DeviceMate features.
