NOTES:

1.

Testing performed at 4.0 MHz with PLL enabled. With the PLL bypassed, the device is only tested

down to 8 MHz. However, the device is static by design and will typically operate below 1 Hz.

2.

Typical specifications, not guaranteed.

3.

Assuming back-to-back bus cycles.

4.

8-bit bus only.
