Product Details
Key Features
- 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
