DS2030AB - Single-Piece 256kb Nonvolatile SRAM

Datasheet Summary

Description

The DS2030 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 components are encased in a surface-mount module with a 256-ball BGA footprint.

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 at 5% or 10% Below Nominal VCC (5V).
  • Reset Output can be used as a CPU Supervisor for a Microprocessor.
  • Industrial Temperature Range (-40°C to +85°C).
  • UL Rec.

Rev 2; 1/05 www.DataSheet4U.com DS2030Y/AB Single-Piece 256kb Nonvolatile SRAM General Description The DS2030 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 components 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. When VCC is powered down or out of tolerance, the controller write-protects the SRAM’s contents and powers the SRAM from the battery. Two versions of the DS2030 are available, which provide either a 5% or 10% power-monitoring trip point.
