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 t
ACS
- t
OE
after the falling edge of ECS# without impact on t
OE
or by t
ACC
- t
OE
after an address change without impact on t
ACC
