TBD = To Be Determined.
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.
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.
