DESCRIPTION

The DS1350W 3.3V 4096K Nonvolatile SRAM is a

4,194,304–bit, fully static, nonvolatile SRAM organized

as 524,288 words by eight bits. Each NV SRAM has a

self–contained lithium energy source and control cir-

data corruption. Additionally, the DS1350W has dedi-

cated circuitry for monitoring the status of V and the

status of the internal lithium battery. DS1350W devices

in the PowerCap Module package are directly surface

mountable and are normally paired with a DS9034PC

PowerCap to form a complete Nonvolatile SRAM mod-

ule. The devices can be used in place of 512K x 8

SRAM, EEPROM or Flash components.

cuitry which constantly monitors V for an out–of–tol-

erance condition. When such a condition occurs, the

lithium energy source is automatically switched on and

write protection is unconditionally enabled to prevent
