28LV64A Datasheet PDF – 64K, Low Voltage CMOS EEPROM

Part Number: 28LV64A

Function: 64K (8Kx8) low voltage CMOS EEPROM

Manufacturer: Microchip Technology

Pinouts:

28LV64A datasheet

 

Description

This is 64K (8K x 8) Low Voltage CMOS EEPROM.

The Microchip Technology Inc. The 28LV64A is a CMOS 64K non-volatile electrically Erasable PROM organized as 8K words by 8 bits.

The 28LV64A is accessed like a static RAM for the read or write cycles without the need of external components. During a “byte write”, the address and data are latched internally, freeing the microprocessor address and data bus for other operations. Following the initiation of write cycle, the device will go to a busy state and automatically clear and write the latched data using an internal control timer.

Features

1. 2.7V to 3.6V Supply

2. Read Access Time : 300 ns

3. CMOS Technology for Low Power Dissipation
(1) 8 mA Active
(2) 50 μA CMOS Standby Current

4. Byte Write Time : 3 ms

5. Data Retention >200 years

6. High Endurance – Minimum 100,000 Erase/Write Cycles

7. Automatic Write Operation
(1) Internal Control Timer
(2) Auto-Clear Before Write Operation
(3) On-Chip Address and Data Latches
