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.
