DS1250W

3.3V 4096k Nonvolatile SRAM

www.maxim-ic.com

FEATURES



10 years minimum data retention in the

absence of external power

Data is automatically protected during power

loss

Replaces 512k 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 standard 32-pin DIP package

PowerCap Module (PCM) package

– Directly surface-mountable module

– Replaceable snap-on PowerCap provides

lithium backup battery

– Standardized pinout for all nonvolatile

SRAM products

– Detachment feature on PCM allows easy

removal using a regular screwdriver
