Test Conditions: Capacitive load on all pins = 100 pF, rise and fall times = 10 ns, F
Exceeding the maximum specification causes additional wait states.
If wait states are used, add 2T
Testing is performed down to 8 MHz, although the device is static by design and will typically operate
below 1 Hz.
Assuming back-to-back bus cycles.
8-bit bus only.
The External Memory System Must Meet These Specifications (Continued)
