DESCRIPTION

The DS1345 1024k NV SRAMs are 1,048,576-bit, fully static, NV SRAMs organized as 131,072 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 DS1345 devices have dedicated circuitry for monitoring the status of VCC and the status of the internal lithium battery.

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 50µA

■ Upgrade for 128k 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 (DS1345Y) or optional ±5 VCC operating range (DS1345AB)

■ 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 easy removal using a regular screwdriver
