• Manufacturer Part Number: 79LV0832RPQE-20
• Description: 8 Megabit (256K x 32-Bit) Low Voltage EEPROM MCM
• Manufacturer: MAXWELL [Maxwell Technologies]

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.
2. RES Signal
Low Voltage 8 Megabit (256K x 32-Bit) EEPROM MCM
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.
RES should be kept at V
