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 imped-
ance state. This two line control prevents bus contention.
NOTES:
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.
