DS1312E - Brand New Maxim Integrated Memory Controllers
-
Description
The DS1312E Nonvolatile Controller with Battery Monitor is a CMOS circuit that is designed to convert CMOS RAM into nonvolatile memory. It solves the problem of converting CMOS RAM into nonvolatile memory by monitoring the incoming power for an out-of-tolerance condition. When an out-of-tolerance condition is detected, the chip enable is inhibited to provide write protection, and the battery is switched on to supply uninterrupted power to the RAM. This controller uses a low-leakage CMOS process to achieve precise voltage detection and 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
- Optional 5% or 10% power-fail detection
- Space-saving 8-pin DIP and SOIC packages
- Optional 16-pin SOIC and 20-pin TSSOP versions reset the processor when power failure occurs and hold the processor in reset during system power-up
- Industrial temperature range of -40°C to +85°C
Application Scenarios
The DS1312E Nonvolatile Controller with Battery Monitor is suitable for applications that require the conversion of CMOS RAM into nonvolatile memory. It is commonly used in electronic devices that require uninterrupted power supply to the RAM, such as data loggers, industrial control systems, and medical devices.
