2 RabbitCore RCM3400
• One additional analog input (CONVERT)
• 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 SRAM, (options for 256K flash memory and 256K 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
• Five 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 configu-
rable as SDLC/HDLC serial ports.
• Supports 1.15 Mbps IrDA transceiver
There are two RCM3400 production models. Table 1 summarizes their main features.
The RCM3400 can be programmed through connections on the motherboard supporting
RS-232, USB with an RS-232/USB converter, or over an Ethernet connection.
Appendix A provides detailed specifications for the RCM3400.
