DS1245Y-70+
NVRAM, SRAM, 1 Mbit, 128K x 8bit, Parallel, 70 ns, DIP
제품 개요
The DS1245Y-70+ is a 1024K Non-volatile (NV) SRAM, 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 conditionally 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 byte wide 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 non-volatile 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-year Minimum data retention in 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
- Full ±10% VCC operating range
- Directly surface-mountable module
- Replaceable snap-on PowerCap provides lithium backup battery
