Rcm3305/Rcm3315 Features - Rabbit RabbitCore RCM3305 User Manual

1.1 RCM3305/RCM3315 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
• 49 parallel 5 V tolerant I/O lines: 43 configurable for I/O, 3 fixed inputs, 3 fixed outputs
• Three additional digital inputs, two additional digital outputs
• External reset
• Alternate 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
• Ten 8-bit timers (six cascadable) and one 10-bit timer with two match registers
• 512K flash memory, 512K program execution SRAM, 512K data SRAM
• Serial-flash mass-storage memory options, which are required to run the optional
Dynamic C FAT file system module and the featured remote application update.
• Real-time clock
• Watchdog supervisor
• Provision for customer-supplied backup battery via connections on header J4
• 10-bit free-running PWM counter and four pulse-width registers
• Two-channel Input Capture (shared with parallel I/O ports) can be used to time input
signals from various port pins
• Two-channel Quadrature Decoder accepts inputs from external incremental encoder
modules
• Five or six 3.3 V CMOS-compatible serial ports with a maximum asynchronous baud
rate of 5.525 Mbps. Three ports are configurable as a clocked serial port (SPI), and two
ports are configurable as SDLC/HDLC serial ports (shared with parallel I/O ports).
• Supports 1.15 Mbps IrDA transceiver
The RCM3900/RCM3910 and RCM3365/RCM3375 RabbitCore modules are similar to
the RCM3305/RCM3315 and RCM3309/RCM3319, but they use fixed NAND or remov-
able media for their mass-storage memories instead of the fixed serial flash options of the
RCM3305/RCM3315 and the RCM3309/RCM3319.
