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 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.
