A.10 Order Numbers
These part numbers are generic numbers only. To place an order, ROM code must be submitted to the
ROM Processing Center (RPC).
Freescale Semiconductor
Internal oscillator base frequency
Internal oscillator tolerance
Internal oscillator multiplier
RAM data retention voltage
Note: Since MC68HC08GT16 is a ROM device, Flash memory electrical characteristics do not apply.
MC08GT16CBE

1. V
2. Internal oscillator is selectable through software for a maximum frequency.
3. f
4. Multiplier must be chosen to limit the maximum bus frequency of 4 MHz for 2.7-V operation and 8 MHz for 4.5-V operation.
Actual frequency will be multiplier (N) x base frequency.
