General Description
The DS2070W is a 16Mb 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 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 mod-
ified. When V
CC
is powered down or out-of-tolerance,
the controller write-protects the SRAM’s contents and
powers the SRAM from the battery. The DS2070W also
contains a power-supply monitor output,
RST
, which can
be used as a CPU supervisor for a microprocessor.
