2 RabbitCore RCM3200
1.2 RCM3200 RabbitCore Modules
Throughout this manual, the term RCM3200 refers to the complete series of RCM3200
RabbitCore modules unless other production models are referred to specifically.
The RCM3200 RabbitCore modules are designed for use on a customer-supplied mother-
board that supplies power and interfaces to real-world I/O devices. Their two 34-pin con-
nection headers provide 52 parallel user I/O lines, shared with five serial ports, along with
control lines. A sixth serial port and one additional I/O line are available on the program-
ming 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 RCM3200 is equipped with a 10/100Base-T Ethernet port, 512K flash memory, a
256K battery-backed program data SRAM, and a 512K program execution SRAM.
There are three RCM3200 production models. 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.
Table 1 below summarizes the main features of the RCM3200.
The RCM3200 can be programed locally, remotely, or via a network using appropriate
interface hardware.
