These ICs are part of the regular series of back-up ICs, and use capacitors (super capacitor, large capacity chemical capacitor) as back-up power supply. They control 1-chip microcomputer high-speed, low-speed, and stand-by modes (MNI control). These ICs also are capable of controlling data save in EPROM and other nonvolatile memories during power outage. |
