Data SRAM 256K 128K 256K
Program Execution SRAM 512K 512K
Backup Battery
Connection for user-supplied backup battery
(to support RTC and data SRAM)
General-Purpose I/O
52 parallel digital I/0 lines:
• 44 configurable I/O
• 4 fixed inputs
• 4 fixed outputs
Additional Inputs Startup mode (2), reset in
Additional Outputs Status, reset out
External I/O Bus
Can be configured for 8 data lines and
6 address lines (shared with parallel I/O lines), plus I/O read/write
Serial Ports
6 shared high-speed, CMOS-compatible ports:
all 6 configurable as asynchronous (with IrDA), 4 as clocked serial (SPI),
and 2 as SDLC/HDLC (with IrDA)
1 asynchronous serial port dedicated for programming
support for MIR/SIR IrDA transceiver
Serial Rate Maximum asynchronous baud rate = CLK/8
Slave Interface
A slave port allows the RCM3200 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
Real-Time Clock Yes
Timers Ten 8-bit timers (6 cascadable), one 10-bit timer with 2 match registers
Watchdog/Supervisor Yes
Pulse-Width Modulators 10-bit free-running counter and four pulse-width registers
Input Capture
2- channel input capture can be used to time input signals from various port
pins
Quadrature Decoder
2-channel quadrature decoder accepts inputs from external incremental
encoder modules
