DS1270AB Datasheet 16m Nonvolatile Sram

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-5615; Rev 11/10 www.maxim-ic.com DS1270Y/AB 16M Nonvolatile.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

A0 – A20 - Address Inputs DQ0 - DQ7 - Data In/Data Out CE - Chip Enable WE - Write Enable OE - Output Enable VCC GND - Power (+5V) - Ground NC - No Connect DESCRIPTION The DS1270 16M Nonvolatile SRAMs are 16,777,216-bit, fully static nonvolatile SRAMs organized as 2,097,152 words by 8 bits.

Each 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 unconditionally enabled to prevent data corruption.

Key Features

  • 5 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 70 ns.
  • Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
  • Full ±10% VCC operating range (DS1270Y).
  • Optional ±5% VCC operating range (DS1270AB).
  • Optional industrial temperature range of -40°C to.
