DS1210
Overview
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.
- 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 PDIP or 16-Pin SO Packages
- Consumes <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 VCC Switch
- Optional Industrial (N) Temperature Range of -40°C to +85°C
