Low Voltage 8 Megabit (256K x 32-Bit) EEPROM MCM
79LV0832
Data Protection
To protect the data during operation and power on/off, the EEPROM has 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 EEPROM to programming mode by mis-
take. To prevent this phenomenon, the EEPROM has a noise cancellation function that cuts noise if its width is 20ns or less in
programming mode. Be careful not to allow noise of a width of more than 20ns on the control pins.
2. RES Signal
RES should be kept at V level when VCC is turned on or off. The EEPROM breaks off programming operation when RES
SS
become low, programming operation doesn’t finish correctly in case that RES falls low during programming operation. RES
should be kept high for 10 ms after the last data is input
