DS1314S+ - Brand New Maxim Integrated Memory Controllers
-
Description
The DS1314S+ is a CMOS circuit designed to convert CMOS RAM into nonvolatile memory. It solves the application problem of converting CMOS RAM into nonvolatile memory. The chip monitors the incoming power for any out-of-tolerance condition. When such a condition is detected, the chip enable is inhibited to accomplish write protection, and the battery is switched on to supply uninterrupted power to the RAM. The DS1314S+ uses special circuitry that utilizes a low-leakage CMOS process. This allows for precise voltage detection at extremely low battery consumption.
Specifications and features
- Converts CMOS SRAM into nonvolatile memory
- Unconditionally write-protects SRAM when VCC is out of tolerance
- Automatically switches to battery backup supply when VCC power failure occurs
- Monitors voltage of a lithium cell and provides advanced warning of impending battery failure
- Signals low-battery condition on active low Battery Warning output signal
- Automatic VCC power-fail detection for 3.0V or 3.3V power supplies
- Space-saving 8-pin DIP and SOIC packages
- Optional 16-pin SOIC and 20-pin TSSOP versions reset processor when power failure occurs and hold processor in reset during system power-up
- Industrial temperature range of -40°C to +85°CApplication Scenarios
The DS1314S+ is ideal for applications where CMOS RAM needs to be converted into nonvolatile memory. It can be used in various devices that require the ability to save data even in the event of a power failure, such as industrial control systems, battery-powered devices, and medical equipment.
Comparison
Advantages- Converts CMOS SRAM into nonvolatile memory, allowing for data retention even in the event of a power failure
