FEATURES
§ 10 years minimum data retention in the
absence of external power
§ Data is automatically protected during power
loss
§ Power supply monitor resets processor when
VCC power loss occurs and holds processor in
reset during VCC ramp-up
§ Battery monitor checks remaining capacity
daily
§ Read and write access times as fast as 70ns
§ Unlimited write cycle endurance
§ Typical standby current 50mA
§ Upgrade for 32k x 8 SRAM, EEPROM or
Flash
§ Lithium battery is electrically disconnected to
retain freshness until power is applied for the
first time
§ Full ±10% VCC operating range (DS1330Y)
or optional
±5% VCC operating range
(DS1330AB)
§ Optional industrial temperature range of
-40
°C to +85°C, designated IND
§ PowerCap Module (PCM) package
-
Directly surface-mountable module
-
Replaceable snap-on PowerCap provides
lithium backup battery
-
Standardized pinout for all nonvolatile
(NV) SRAM products
-
Detachment feature on PowerCap allows

DESCRIPTION
The DS1330 256k NV SRAMs are 262,144-bit, fully static, NV SRAMs organized as 32,768 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 source
is automatically switched on and write protection is unconditionally enabled to prevent data corruption.
Additionally, the DS1330 devices have dedicated circuitry for monitoring the status of VCC and the status
of the internal lithium battery. DS1330 devices in the PowerCap module package are directly surface
mountable and are normally paired with a DS9034PC PowerCap to form a complete NV SRAM module.
The devices can be used in place of 32k x 8 SRAM, EEPROM, or Flash components.
