Description
The DS1210 Nonvolatile Controller Chip 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 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.

Key Features
  • Converts CMOS RAMs into Nonvolatile Memories
  • Unconditionally Write Protects when VCC is Out-of-Tolerance
  • Automatically Switches to Battery when Power-Fail Occurs
  • Space-Saving 8-Pin DIP
  • Consumes Less Than 100nA of Battery Current
  • Tests Battery Condition on Power up
  • Provides for Redundant Batteries
  • Optional 5% or 10% Power-Fail Detection
  • Low Forward Voltage Drop on the VCCSwitch
  • Optional 16-Pin SO Surface Mount Package
  • Optional Industrial (N) Temperature Range of -40°C to +85°C
  • UL Certified
