General Description

A0 A17 - Address Inputs DQ0 DQ7 - Data In/Data Out CE - Chip Enable WE - Write Enable OE - Output Enable VCC GND - Power (+3.3V) - Ground NC - No Connect DESCRIPTION The DS1249W 2048kb nonvolatile (NV) SRAMs are 2,097,152-bit, fully static, NV SRAMs organized as 262,144 wo

Key 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 of 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 DS1249W 3.3V 2048kb Nonvolatile SRAM PIN.
