The RCM2200 is an advanced module that incorporates the pow-
erful Rabbit 2000
™
microprocessor, flash memory, static RAM,
digital I/O ports, and a 10Base-T Ethernet port, all on a PCB just
half the size of a business card.
1.1 RCM2200 Description
The RCM2200 is a small-footprint module designed for use on a motherboard that sup-
plies power and interface to real-world I/O devices. Its two 26-pin connection headers pro-
vide 26 parallel user I/O lines, shared with three serial ports, along with data, address and
control lines. A fourth serial port and three additional I/O lines are available on the pro-
gramming header.
A fully-enabled slave port permits glueless master-slave interface with another Rabbit-
based system. The slave port may also be used with non-Rabbit systems, although addi-
tional logic may be required.
The RCM2200 is equipped with a 10Base-T Ethernet port, 256K flash memory and 128K
static RAM.
There are three production models in the RCM2200 series. If the standard models do not
serve your needs, other variations can be specified and ordered in production quantities.
Contact your Z-World or Rabbit Semiconductor sales representative for details.
