    When a 5 V signal is applied to 5 V tolerant pins, they present a high impedance even if the Rabbit power is off. The 5 V tolerant feature allows 5 V devices that have a suitable switching threshold to be connected directly to the RCM3100. This includes HCT family parts operated at 5 V that have an input threshold between 0.8 and 2 V.

  • Page 31: Serial Communication

    Either of the two communicating devices can sup- ply the clock. When the Rabbit 3000 provides the clock, the baud rate can be up to 80% of the system clock frequency divided by 128, or 183,750 bps for a 29.4 MHz clock speed.

  • Page 94: Appendix D. Power Supply

    The RCM3100 does not have a battery, but there is provision for a customer-supplied bat- tery to back up SRAM and keep the internal Rabbit 3000 real-time clock running. Header J2, shown in Figure D-1, allows access to the external battery. This header makes it possible to connect an external 3 V power supply.

  • Page 95: Reset Generator

    D.1.2 Reset Generator The RCM3100 uses a reset generator to reset the Rabbit 3000 microprocessor when the volt- age drops below the voltage necessary for reliable operation. The reset occurs between 2.55 V and 2.70 V, typically 2.63 V. The RCM3100 has a reset output, pin 1 on header J2.

    Parallel Port F, along with +5 V. This appendix describes the function of each pin, and the ways they may be used for motion-control applications. It should be read in conjunction with the Rabbit 3000 Microprocessor User’s Manual and the RCM3100 and the RCM3000/RCM3100/RCM3200 Prototyping Board schematics.
