RCM3700
Low-EMI Rabbit 3000
10/100-compatible with 10Base-T interface, RJ-45, 2 LEDs
512K
512K
Connection for user-supplied backup battery
(to support RTC and SRAM)
33 parallel digital I/0 lines:
Can be configured for 8 data lines and
5 address lines (shared with parallel I/O lines), plus I/O read/write
Four 3.3 V CMOS-compatible ports configurable as:
•
4 asynchronous serial ports (with IrDA) or
•
3 clocked serial ports (SPI) plus 1 HDLC (with IrDA) or
•
1 clocked serial port (SPI) plus 2 HDLC serial ports (with IrDA)
Maximum asynchronous baud rate = CLK/8
A slave port allows the RCM3700 to be used as an intelligent peripheral
device slaved to a master processor, which may either be another Rabbit
3000 or any other type of processor
Ten 8-bit timers (6 cascadable, 3 reserved for internal peripherals),
one 10-bit timer with 2 match registers
4 PWM output channels with 10-bit free-running counter
2-channel input capture can be used to time input signals from various
port pins
•
1 quadrature decoder unit accepts inputs from external incremental
encoder modules or
•
1 quadrature decoder unit shared with 2 PWM channels
100 mA @ 22.1 MHz, 5 V; 78 mA @ 11.05 MHz, 5 V
