Note:
* Post-radiation performance guaranteed at 25 °C per MIL-STD-883 Method 1019 at 1.0E5 rads(Si).
1. If max exceeded, additional wait state occurs.
2. If wait states are used, add 2 TOSC *N, where N = number of wait states.
3. Assuming back-to-back bus cycles.
4. 8-bit only
5. Tested only at initial qualification, and after any design or process changes which may affect this characteristic.
6. These specs are verified using functional vectors (strobed) only.
7. Low speed tests performed at 5MHz. 1MHz operation is guaranteed by design.
