DS2030Y/AB Single-Piece 256kb

Nonvolatile SRAM

General Description

Features

♦ Single-Piece, Reflowable, 27mm²PBGA Package

The DS2030 is a 256kb reflowable nonvolatile (NV)

SRAM, which consists of a static RAM (SRAM), an NV

controller, and an internal rechargeable manganese lithi-

um (ML) battery. These components are encased in a

surface-mount module with a 256-ball BGA footprint.

Footprint

♦ Internal ML Battery and Charger

♦ Unconditionally Write-Protects SRAM when V

is Out-of-Tolerance

Whenever V

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 modi-

fied. When V

is powered down or out of tolerance, the

♦ Internal Power-Supply Monitor Detects Power Fail

at 5% or 10% Below Nominal V (5V)

controller write-protects the SRAM’s contents and pow-

ers the SRAM from the battery. Two versions of the

DS2030 are available, which provide either a 5% or 10%

power-monitoring trip point. The DS2030 also contains a

power-supply monitor output, RST, which can be used

as a CPU supervisor for a microprocessor.
