DS1314+

Controllers Overview

The DS1314+ 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 supports a supply voltage of 3V to 3.6V. The component is housed in an 8-pin PDIP package with through-hole mounting. It functions as a memory controller type for nonvolatile RAM.

Controllers Feature Summary

Converts standard CMOS SRAM into nonvolatile memory by managing power transitions between system supply and backup battery.
Unconditionally write-protects connected SRAM when the main power supply falls out of tolerance.
Monitors lithium cell voltage to provide advanced warning of impending battery failure via a dedicated output signal.
Automatically switches to battery backup supply upon detection of a VCC power failure.

Controllers Applications

Battery backup support for SRAM modules
Lithium battery monitoring in embedded systems
Nonvolatile memory controller integration

Controllers Procurement Notes

Verify the specific package variant required, as the DS1314 family includes 8-pin DIP, 8-pin SOIC, 16-pin SOIC, and 20-pin TSSOP options. Confirm RoHS compliance status, indicated by the '+' suffix in the part number. Check current availability as distribution may vary. Ensure the selected version matches the pinout requirements for the target PCB design.

Controllers Selection Notes

Select the DS1314+ when a low-power solution is needed to maintain SRAM data during power interruptions without complex external circuitry. Consider the 8-pin DIP package for prototyping or through-hole applications. Evaluate the need for battery warning features if long-term data retention reliability is critical. Compare against other NV controllers based on available supply voltage ranges and package constraints.

Controllers Part Context

The DS1314 belongs to a family of nonvolatile controllers that simplify the implementation of battery-backed memory systems. It integrates power-fail detection, write protection, and battery monitoring into a single CMOS circuit. This reduces board space and component count compared to discrete solutions.
