2 RabbitCore RCM3209/RCM3229
1.1 RCM3209/RCM3229 Features
•
Small size: 1.85" x 2.73" x 0.86"
(47 mm x 69 mm x 22 mm)
•
Microprocessor: Rabbit 3000 running at 44.2 MHz
•
(RCM3209 only) 10/100Base-T auto MDI/MDIX Ethernet port chooses Ethernet inter-
face automatically based on whether a crossover cable or a straight-through cable is
used in a particular setup
•
52 parallel 5 V tolerant I/O lines: 44 configurable for I/O, 4 fixed inputs, 4 fixed outputs
•
Two additional digital inputs, two additional digital outputs
•
External reset input
•
Alternate I/O bus can be configured for 8 data lines and 6 address lines (shared with
parallel I/O lines), I/O read/write
•
Ten 8-bit timers (six cascadable) and one 10-bit timer with two match registers
•
512K flash memory, 512K program execution SRAM, 256K data SRAM
•
Real-time clock
•
Watchdog supervisor
•
Provision for customer-supplied backup battery via connections on header J2
•
10-bit free-running PWM counter and four 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
•
Six CMOS-compatible serial ports: maximum asynchronous baud rate of 5.5 Mbps. Four
ports are configurable as a clocked serial port (SPI), and two ports are configurable as
SDLC/HDLC serial ports.
•
Supports 1.15 Mbps IrDA transceiver.
The RCM3209 and RCM3229 modules are similar in form, dimensions, and function to
the RCM3200/RCM3220, and based on the RCM3900 RabbitCore modules which were
first released in 2008. The RCM3900/RCM3910 and RCM3309/RCM3319 RabbitCore
modules are similar to the RCM3209/RCM3229, but they offer fixed NAND and/or
removable media mass-storage memories.The RCM3309 and the RCM3319 offer fixed
serial flash mass-storage options instead.
