WE, CE Pin Operation
During a write cycle, addresses are latched by the falling edge of WE or CE, and data is latched by the rising edge of
WE or CE.
Data Polling
Data Polling function allows the status of the EEPROM to be determned. If EEPROM is set to read mode during a
write cycle, an inversion of the last byte of data to be loaded outputs fromI/O 7 to indicate that the EEPROMis per-
formng a write operation.
RDY/Busy Signal
RDY/Busy signal also allows a comparison operation to determne the status of the EEPROM The RDY/Busy signal
has high impedance except in write cycle and is lowered to V
OL
after the first write signal. At the-end of a write cycle,
the RDY/Busy signal changes state to high impedance.
RES Signal
When RES is LOW, the EEPROMcannot be read and programmed. Therefore, data can be protected by keeping
RES low when V
CC
is switched. RES should be high during read and programmng because it doesnt provide a latch
function.
Data Protection
To protect the data during operation and power on/off, the EEPROMhas the internal functions described below
1. Data Protection against Noise of Control Pins (CE, OE, WE) during Operation.
