DS2030W Datasheet 3.3v Single-piece 256k Nonvolatile Sram

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Rev 0; 10/04 .. DS2030W 3.3V Single-Piece 256k Nonvolatile SRAM General.

General Description

The DS2030W is a 256kb reflowable nonvolatile (NV) SRAM, which consists of a static RAM (SRAM), an NV controller, and an internal rechargeable manganese lithium (ML) battery.

These ponents are encased in a surface-mount module with a 256-ball BGA footprint.

Whenever VCC is applied to the module, it recharges the ML battery, powers the SRAM from the external power source, and allows the contents of the SRAM to be modified.

Key Features

  • Single-Piece, Reflowable, PBGA Package Footprint.
  • Internal ML Battery and Charger.
  • Unconditionally Write-Protects SRAM when VCC is Out-of-Tolerance.
  • Automatically Switches to Battery Supply when VCC Power Failures Occur.
  • Internal Power-Supply Monitor Detects Power Fail Below Nominal VCC (3.3V).
  • Reset Output can be used as a CPU Supervisor for a Microprocessor.
  • Industrial Temperature Range (-40°C to +85°C).
  • UL Recognized DS.
