Vtest

0.4 VCC

Input signal

edge rate

1 V/ns

Note:

1. The input test environment uses 0.1 VCC of overdrive over VIH and VIL. Timing parameters must

be met with no more overdrive than this. Vmax specifies the maximum peak-to-peak waveform

allowed for measuring the input timing. Production testing may use different voltage values, but

must correlate results back to these parameters.

Reset Operations

tPLPH

RST# or INIT# pulse low time (If RST# or INIT# is tied

to VCC, this specification is not applicable.)

Note:

1. There will be a 20-

µs reset latency if a reset procedure is performed during a programming or

erase operation.
