The Rabbit 2000 processor may be operated at voltages between 2.5 V and 5.5 V, and at
temperatures from –40°C to +85°C with use possible use over the range -55°C to +120°C.
Most users will operate the Rabbit at either 5.0 V or 3.3 V. The most computation per watt
is obtained at approximately 3.3 V. The highest practical speed is usually obtained at 5 V.
The Rabbit is available in one version, which has a maximum clock speed of 29.4 MHz over the
industrial temperature range of -40°C to +85°C. The R30 has a maximum clock speed of 18.9
MHz at 3.3 V ±10%. The maximum clock speed is 11.5 MHz at 2.5 V.
If a half-speed crystal is used with the clock doubler to achieve the desired clock speed, the
maximum clock speed must be reduced by 4% to allow for an up to 4% asymmetry (52/48)
in the waveform generated by the oscillator. This is because the clock doubler uses the inter-
mediate edge to generate the double frequency. If the clock doubler is used to double
14.7456 MHz to 29.4912 MHz, the operating temperature should be limited to 70°C.
To optimize power consumption, the usual strategy is to use a supply voltage between 3 V
and 3.5 V, and the clock speed should be adjusted downward as far as feasible. This will
give the maximum computation per watt.
