These parameters are characterized but not tested.

† Data in the Typical (“Typ”) column is at 5V, 25

°C unless otherwise stated. These parameters are for design

guidance only and are not tested.

Note 1:

To ensure these oscillator frequency tolerances, VDD and VSS must be capacitively decoupled as close to

the device as possible. 0.1

μF and 0.01 μF values in parallel are recommended.

The 4 MHz clock is derived from the 8 MHz oscillator. To obtain 4 MHz tolerance values, divide the

appropriate 8 MHz value by 2.

CL = 50 pF for all pins
