Description

A0 - A16 - Address Inputs DQ0 - DQ7 - Data In/Data Out CE - Chip Enable WE - Write Enable OE - Output Enable VCC GND - Power (+3.3V) - Ground NC - No Connect 1 of 10 DS1245W DESCRIPTION The DS1245W 3.3V 1024k Nonvolatile SRAM is a 1,048,576-bit, fully static, nonvolatile SRAM organized as 131,072 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,

Features

10 years minimum data retention in the absence of external power.
Data is automatically protected during power loss.
Replaces 128k x 8 volatile static RAM, EEPROM or Flash memory.
Unlimited write cycles.
Low-power CMOS.
Read and write access times of 100ns.
Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
Optional industrial temperature range of -40°C to +85°C, designated IND.
JEDEC sta.
