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.
During readout or standby, noise on the control pins may act as a trigger and turn the EEPROMto programmng mode by ms-
take. To prevent this phenomenon, the EEPROMhas a noise cancellation function that cuts noise if its width is 20 ns or less in
programmng mode. Be careful not to allow noise of a width of more than 20 ns on the control pins.
2. Data Protection at V
CC
on/off
