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 as fast as 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

DESCRIPTION
The DS1265W 8Mb nonvolatile (NV) SRAMs are 8,388,608-bit, fully static, NV SRAMs organized as
1,048,576 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control
circuitry that constantly monitors V
CC
for an out-of-tolerance condition. When such a condition occurs,
the lithium energy source is automatically switched on and write protection is unconditionally enabled to
prevent data corruption. There is no limit on the number of write cycles that can be executed and no
additional support circuitry is required for microprocessor interfacing.
