Nonvolatile Controller x 4 Chip

DESCRIPTION\nThe DS1221 Nonvolatile Controller x 4 Chip is a CMOS circuit which solves the application problem of converting CMOS RAMs into nonvolatile memories. Incoming power is monitored for an out-of tolerance condition. When such a condition is detected, the chip enable outputs are inhibited to ■ Converts CMOS RAMs into nonvolatile memories\n■ Data is automatically protected during power loss\n■ 2-to-4 decoder provides for up to 4 CMOS RAMs\n■ Provides for redundant batteries\n■ Test battery condition on power-up\n■ Full ±10% operating range\n■ Unauthorized access can be prevented with;
