DS2065W 3.3V Single-Piece 8Mb

Nonvolatile SRAM

General Description

Features

♦ Single-Piece, Reflowable, 27mm²PBGA Package

The DS2065W is a 8Mb 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.

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 mod-

ified. When V

is powered down or out-of-tolerance,

♦ Internal Power-Supply Monitor Detects Power Fail

the controller write-protects the SRAM’s contents and

powers the SRAM from the battery. The DS2065W also

contains a power-supply monitor output, RST, which can

be used as a CPU supervisor for a microprocessor.
