NOTES
1 Testing performed at 4 0 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
5 If wait states are used add 2 Tosc c n where n e number of wait states If mode 0 (1 automatic wait state added)
operation is selected add 2 TOSC to specification
6 TOFD is the time for the oscillator fail detect circuit (OFD) to react to a clock failure The OFD circuitry is enabled by
programming the UPROM location 0778H with the value 0004H Programming the CDE bit enables oscillator fail detec-
