    1. I NTRODUCTION The RCM3600 is a compact module that incorporates the pow- erful Rabbit ® 3000 microprocessor, flash memory, static RAM, and digital I/O ports. The Development Kit has what you need to design your own microprocessor-based system: a complete Dynamic C software development system and a Prototyping Board that acts as a motherboard to allow you to evaluate the RCM3600 and to pro- totype circuits that interface to the RCM3600 module.
  • Page 8 There are two RCM3600 production models. If the standard models do not serve your needs, 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 RCM3600.

  • Page 87: B.4.3.1 Rs-232

    B.4.3.1 RS-232 RS-232 serial communication on the RCM3600 Prototyping Board is supported by an RS-232 transceiver installed at U4. This transceiver provides the voltage output, slew rate, and input voltage immunity required to meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit 3000’s signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circuit so that a +5 V output becomes approximately -10 V and 0 V is output as +10 V.
