CLOCK AND TIMING CHARACTERISTICS (Cont’d)
Notes:
1. Resonator characteristics given by the ceramic resonator manufacturer.
2. tSU(OSC) is the typical oscillator start-up time measured between VDD=2.8V and the fetch of the first instruction (with a
quick VDD ramp-up from 0 to 5V (<50s).
3. Resonators all have different characteristics. Contact the manufacturer to obtain the appropriate values of external
components and to verify oscillator performance.
4. 3rd overtone resonators require specific validation by the resonator manufacturer.
