Description

A0 A17 - 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 DESCRIPTION The DS1249W 2048kb nonvolatile (NV) SRAMs are 2,097,152-bit, fully static, NV SRAMs organized as 262,144 words by 8 bits.Each NV SRAM has a self-contained lithium energy source and control circuitry that constantly monitors VCC for an out-of-tolerance condition.When such a condition occurs, the lithium e

Features

10 years minimum data retention in the absence of external power.
Data is automatically protected during power loss.
Unlimited write cycles.
Low-power CMOS operation.
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 (IND) temperature range of -40°C to +85°C.
