Description

A0-A10 DQ0-DQ7 - Address Inputs - Data In/Data Out CE - Chip Enable WE - Write Enable OE VCC GND - Output Enable - Power (+5V) - Ground DESCRIPTION The DS1220AB and DS1220AD 16k Nonvolatile SRAMs are 16,384-bit, fully static, nonvolatile SRAMs organized as 2048 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 automaticall

Features

10 years minimum data retention in the absence of external power.
Data is automatically protected during power loss.
Directly replaces 2k x 8 volatile static RAM or EEPROM.
Unlimited write cycles.
Low-power CMOS.
JEDEC standard 24-pin DIP package.
Read and write access times of 100 ns.
Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
Full ±10% VCC operating range (DS1220AD).
Option.
