Controllers datasheet and documents for DS1312+
Controllers Overview
The DS1312+ is a nonvolatile RAM controller IC manufactured by Analog Devices Inc./Maxim Integrated, designed to convert CMOS SRAM into nonvolatile memory. It operates within an industrial temperature range of -40°C to +85°C and accepts a supply voltage between 4.75V and 5.5V. The device is housed in an 8-pin PDIP package with through-hole mounting. It features battery backup switching, power-fail detection, and lithium cell monitoring capabilities.
Controllers Feature Summary
- Converts standard CMOS SRAM into nonvolatile memory by managing power transitions
- Unconditionally write-protects attached SRAM when the main supply voltage falls out of tolerance
- Automatically switches to a lithium battery backup supply upon system power failure
- Monitors lithium battery voltage and signals low-battery conditions via an active-low output
Controllers Applications
- Battery backup support for SRAM modules
- Lithium battery capacity monitoring systems
- Processor-based systems requiring power-fail warning signals
Controllers Procurement Notes
Verify that the specific component matches the 8-pin PDIP package configuration. Confirm the operating temperature range requirements align with the specified -40°C to +85°C industrial limits. Ensure the system supply voltage remains within the 4.75V to 5.5V operational window for correct functionality.
Controllers Selection Notes
Select this component when converting CMOS SRAM to nonvolatile storage is required. Consider the 8-pin DIP package constraint. Evaluate if the integrated battery monitoring and power-fail protection features meet the system reliability requirements without needing external circuitry.
Controllers Part Context
The DS1312+ belongs to the DS1312 family of nonvolatile controllers from Maxim Integrated. It addresses the common application problem of maintaining data integrity in volatile memory during power interruptions by integrating control logic, battery management, and protection circuits into a single CMOS device.
