MITSUMI Battery Backup IC Battery Backup IC 1. Background of Development Around 1985 when began the sales of IC for microcomputer peripheral equipment and system reset IC, a set manufacture inquired of us about IC for control of memory. It was a good change for us to decide a joint development of general purpose IC. This resulted in the development of PST531 and PST532. In 1989 they were improved into the backup IC series dedicated to cards, games (popular-priced) and to 1-chip microcomputers. Our IC series now includes low current consumption type products. 2. What is Battery Backup IC? Such IC memories as S-RAM and D-RAM all volatilize when power supply is cut off.
