1. 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 (<50µs).

) 2. Resonators all have different characteristics. Contact the manufacturer to obtain the appropriate values of external

t(s components and to verify oscillator performance.

3. Resonator characteristics given by the ceramic resonator manufacturer.

c 4. 3rd overtone resonators require specific validation by the resonator manufacturer.

Note:

To reduce disturbance to the RC oscillator, it is recommended to place decoupling

capacitors between VDD and VSS as shown in Figure 88 on page 173.
