DS1230W
3.3V 256K Nonvolatile SRAM
DS1230W
PRELIMINARY
030598 1/11
FEATURES
10 years minimum data retention in the absence of
external power
Data is automatically protected during power loss
Replaces 32K x 8 volatile static RAM, EEPROM or
Flash memory
Unlimited write cycles
Low–power CMOS
Read and write access times as fast as 150 ns
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 28–pin DIP package
New PowerCap Module (PCM) package
– Directly surface–mountable module
– Replaceable snap–on PowerCap provides lith-
ium backup battery
– Standardized pinout for all nonvolatile SRAM
products
– Detachment feature on PowerCap allows easy
removal using a regular screwdriver
