DS1321 Flexible Nonvolatile Controller with Lithium Battery Monitor

DS1321 Flexible Nonvolatile Controller with Lithium Battery Monitor Series Datasheet

The MAXIM INTEGRATED PRODUCTS DS1321 Flexible Nonvolatile Controller with Lithium Battery Monitor is a CMOS circuit which solves the application problem of converting CMOS SRAMs into nonvolatile memory. Incoming power is monitored for an out-of-tolerance condition. When such a condition is detected, chip enable outputs are inhibited to accomplish write protection and the battery is switched on to supply the SRAMs with uninterrupted power. Special circuitry uses a low-leakage CMOS process which affords precise voltage detection at extremely low battery consumption. One DS1321 can support as many as four SRAMs arranged in any of three memory configurations.
