1.1 RCM5700/RCM6700 Features
• Small size: ranges from 1.20" × 2.00" × 0.12" (30 mm × 51 mm × 3 mm) for the RCM5700/
RCM6700 model to 1.20" × 2.00" × 0.73" (30 mm × 51 mm × 19 mm) for the RCM5760/
RCM6760 model
• Microprocessor: RCM5700: Rabbit 5000 running at 50.0 MHz, RCM6700: Rabbit 6000 run-
ning at 187.5 MHz
• Up to 35 general-purpose I/O lines each configurable with up to four alternate functions
• 3.3 V I/O lines
• Six CMOS-compatible serial ports — four ports are configurable as a clocked serial port (SPI),
and two ports are configurable as SDLC/HDLC serial ports
• Ethernet PHY interface chooses Ethernet interface automatically based on whether a crossover
cable or a straight-through cable is used in a particular setup
• External I/O bus can be configured for 8 data lines, 8 address lines (shared with parallel I/O
lines), and I/O read/write
• RCM5700: 128KB SRAM (on Rabbit 5000 chip) and 1MB flash memory, with 2MB serial
flash and 512KB SRAM on RCM5750/RCM5760 models.
RCM6700: 1MB SRAM (on Rabbit 6000 chip) and 1MB serial flash, with 4MB serial flash
and additional 1MB external SRAM on RCM6750/6760 models.
• Real-time clock (battery-backable on all models except the RCM5750/5760)
• Watchdog supervisor
There are four RCM5700 production models. Table 1-1 summarizes their main features.
