System Reset (with battery back-up)
Monolithic IC MM1027, 1081
Outline
These ICs were developed for STATIC-RAM (S-RAM) battery back-up, and have built-in switching circuit for
main power supply and battery, back-up timing circuit and battery checker.
Power ON/OFF and momentary power interruptions can damage S-RAM data on equipment that contains an
S-RAM. These ICs switch the S-RAM to back-up mode (CS signal makes S-RAM CE pin low and CE
when power supply voltage goes below a set voltage (detection voltage 4.2V typ., variable), preventing
damage to data. Further, when power supply voltage drops, these ICs switch from main power supply to
battery back-up (switching voltage 3.3V typ.). Then, when power supply voltage rises, they first switch the S-
RAM from battery back-up state to main power supply (switching voltage 3.3V typ.), and from back-up mode
to normal mode (CS signal makes S-RAM CE pin high and CE
reliable protection against data damage. The CS signal also can absorb power supply chattering and
roughness through the external capacitor.
There is a built-in battery checker to monitor the back-up battery voltage, and this circuit is turned ON/OFF by
the control pin.
