• Manufacturer Part Number: 28LV010RPDB-20
• Description: 3.3V 1 Megabit (128K x 8-Bit) EEPROM
• Manufacturer: MAXWELL [Maxwell Technologies]

RES Signal
When RES is LOW, the EEPROM cannot be read and programmed. Therefore, data can be protected by keeping
RES low when V
function.
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. Data Protection at V
3.3V 1 Megabit (128K x 8-Bit) EEPROM
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 20 ns or less in
programming mode. Be careful not to allow noise of a width of more than 20 ns on the control pins.
CC
is switched. RES should be high during read and programming because it doesn’t provide a latch
CC
