Description

A0 - A17 - Address Inputs DQ0 - DQ7 - Data In/Data Out CE - Chip Enable WE - Write Enable OE - Output Enable VCC GND - Power (+5V) - Ground NC - No Connect DESCRIPTION The DS1249 2048k Nonvolatile SRAMs are 2,097,152-bit, fully static, nonvolatile SRAMs organized as 262,144 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 sourc

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 70 ns.
Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
Full ± 10% VCC operating range (DS1249Y).
Optional ± 5% VCC operating range (DS1249AB).
Optional industrial temperature range of -40°C.
