Product Summary

The DS1210 is a Nonvolatile Controller Chip. The device is a CMOS circuit which solves the application problem of converting CMOS RAM into nonvolatile memory. Incoming power is monitored for an out-of-tolerance condition. When such a condition is detected, chip enable of the DS1210 is inhibited to accomplish write protection and the battery is switched on to supply the RAM with uninterrupted power. Special circuitry uses a low-leakage CMOS process which affords precise voltage detection at extremely low battery consumption.The 8-pin DIP package keeps PC board real estate requirements to a minimum. By combining the DS1210 Nonvolatile Controller Chip with a CMOS memory and batteries, nonvolatile RAM operation can be achieved.

Parametrics

DS1210 absolute maximum ratings: (1)Voltage on Any Pin Relative to Ground: -0.3V to +7.0V; (2)Operating Temperature: 0 to 70℃; (3)Storage Temperature: -55 to +125℃; (4)Soldering Temperature: 260℃ for 10 seconds.

Features

DS1210 features: (1)Converts CMOS RAMs into nonvolatile memories; (2)Unconditionally write protects when VCC is out of tolerance; (3)Automatically switches to battery when power-fail occurs; (4)Space saving 8-pin DIP; (5)Consumes less than 100 nA of battery current; (6)Tests battery condition on power up; (7)Provides for redundant batteries; (8)Optional 5% or 10% power-fail detection; (9)Low forward voltage drop on the VCC switch; (10)Optional 16-pin SOIC surface mount package; (11)Optional industrial temperature range of -40 to +85℃.
