The DS1245 1024k Nonvolatile (NV) SRAMs are 1,048,576-bit, fully static, nonvolatile SRAMs organized as 131,072 words by 8 bits. Each complete 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 nconditionally enabled to prevent data corruption. DIP-package DS1245 devices can be used in place of existing 128k x 8 static RAMs directly conforming to the popular bytewide 32-pin DIP standard. DS1245 devices in the PowerCap Module package are directly surface mountable and are normally paired with a DS9034PC PowerCap to form a complete Nonvolatile SRAM module. There is no limit on the number of write cycles that can be executed and no additional support circuitry is required for microprocessor interfacing.
* 10 years minimum data retention in the absence of external power
* Data is automatically protected during power loss
* Replaces 128k x 8 volatile static RAM, EEPROM or Flash memory
* Unlimited write cycles
* Low-power CMOS
* Read and write access times of 70ns
* Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time
* Full ±10% VCC operating range (DS1245Y)
* Optional ±5% VCC operating range (DS1245AB)
* Optional industrial temperature range of -40°C to +85°C, designated IND
* JEDEC standard 32-pin DIP package
* PowerCap Module (PCM) package
* Directly surface-mountable module
* Replaceable snap-on PowerCap provides lithium backup battery
* Standardized pinout for all nonvolatile SRAM products
* Detachment feature on PowerCap allows easy removal using a regular screwdriver
