DS1249W-100規(guī)格書詳情

DESCRIPTION

The DS1249W 2048kb nonvolatile (NV) SRAMs are 2,097,152-bit, fully static, NV SRAMs organized as 262,144 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry that 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. There is no limit on the number of write cycles that can be executed, and no additional support circuitry is required for microprocessor interfacing.

FEATURES

? 10 years minimum data retention in the absence of external power

? Data is automatically protected during power loss

? Unlimited write cycles

? Low-power CMOS operation

? Read and write access times as fast as 100ns

? Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time

? Optional industrial (IND) temperature range of -40°C to +85°C

? JEDEC standard 32-pin DIP package
