FIGURE 9 – EEPROM READ WAVEFORMS
EEPROM READ
The WSE128K16-XXX EEPROM stores data at the
memory location determined by the address pins. When
ECS# and OE# are low and EWE# is high, this data is
present on the outputs. When ECS# and OE# are high,
the outputs are in a high impedance state. This two line
control prevents bus contention.
Note: OE# may be delayed up to tACS - tOE after the falling edge of ECS# without impact on tOE or by tACC - tOE after an address change without impact on tACC.
