General Description
The DS3070W consists of a static RAM, a nonvolatile
(NV) controller, a year 2000-compliant real-time clock
(RTC), and an internal rechargeable manganese lithium
(ML) battery. These components are encased in a sur-
face-mount module with a 256-ball BGA footprint.
Whenever V
CC
is applied to the module, it recharges
the ML battery, powers the clock and SRAM from the
external power source, and allows the contents of the
clock registers or SRAM to be modified. When V
CC
is
powered down or out-of-tolerance, the controller write-
protects the memory contents and powers the clock
and SRAM from the battery. The DS3070W also con-
tains a power-supply monitor output (
RST
), as well as a
user-programmable interrupt output (
IRQ
/FT).
