DS2030Y/AB Single-Piece 256kb
Nonvolatile SRAM
General Description
Features
The DS2030 is a 256kb reflowable nonvolatile (NV)
o Single-Piece, Reflowable,
27mm 2
PBGA Package
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.
Whenever V CC 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 CC is powered down or out of tolerance, the
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.
Applications
Footprint
o Internal ML Battery and Charger
o Unconditionally Write-Protects SRAM when V CC
is Out-of-Tolerance
o Automatically Switches to Battery Supply when
V CC Power Failures Occur
o Internal Power-Supply Monitor Detects Power Fail
at 5% or 10% Below Nominal V CC (5V)
o Reset Output can be used as a CPU Supervisor
for a Microprocessor
o Industrial Temperature Range (-40 ° C to +85 ° C)
o UL Recognized
