DS1225AB Product details

Description

A0-A12 - Address Inputs DQ0-DQ7 - Data In/Data Out CE - Chip Enable WE - Write Enable OE VCC GND NC - Output Enable - Power (+5V) - Ground - No Connect DESCRIPTION The DS1225AB and DS1225AD are 65,536-bit, fully static, nonvolatile SRAMs organized as 8192 words by 8 bits.Each NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors VCC for an out-of-tolerance condition.When such a condition occurs, the lithium energy source is automatically sw

Features

10 years minimum data retention in the absence of external power.
Data is automatically protected during power loss.
Directly replaces 8k x 8 volatile static RAM or EEPROM.
Unlimited write cycles.
Low-power CMOS.
JEDEC standard 28-pin DIP package.
Read and write access times of 70 ns.
Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
Full ±10% VCC operating range (DS1225AD).
Optiona.
