RabbitCore RCM3750
10/100Base-T RJ-45 Ethernet port
512K flash memory and 512K SRAM (options for 256K flash memory and 128K SRAM)
1 Mbyte serial flash memory, which is required to run the optional Dynamic C FAT file
system
Real-time clock
Watchdog supervisor
Provision for customer-supplied backup battery via connections on header J1
10-bit free-running PWM counter and four pulse-width registers
Two-channel Input Capture can be used to time input signals from various port pins
Two-channel Quadrature Decoder accepts inputs from external incremental encoder
modules
Four available 3.3 V CMOS-compatible serial ports: maximum asynchronous baud rate
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.
Supports 1.15 Mbps IrDA transceiver
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.
