Table 1 below summarizes their main features of the RCM3750.
The RCM3750 is programmed over a standard PC serial port through a programming cable
supplied with the Development Kit, and can also be programed through a USB port with an
RS-232/USB converter or over an Ethernet with the RabbitLink (both available from Rabbit
Semiconuctor).
Appendix A provides detailed specifications for the RCM3750.

of 2.76 Mbps. Three ports are configurable as a clocked serial port (SPI), and one port
is configurable as an HDLC serial port. Shared connections to the Rabbit microproces-
sor make a second HDLC serial port available at the expense of two of the SPI config-
urable ports, giving you two HDLC ports and one asynchronous/SPI serial port.
