DS1210SN+

Controllers Overview

The DS1210SN+ is a nonvolatile controller chip designed to convert standard CMOS RAM into nonvolatile memory. It operates within a supply voltage range of 4.75V to 5.5V and consumes less than 100nA in battery backup mode. The device features an optional industrial temperature range of -40°C to +85°C and utilizes a 16-pin SO package.

Controllers Feature Summary

• Converts CMOS RAM into nonvolatile memory by monitoring incoming power for out-of-tolerance conditions
• Automatically switches to battery backup during power failure while unconditionally write-protecting the memory
• Tests battery condition on power-up to prevent data loss from low battery voltage
• Supports redundant batteries with internal isolation switching for enhanced reliability

Controllers Applications

• Microprocessor-based systems requiring persistent data storage
• Applications necessitating automatic battery backup during power failures
• Systems utilizing redundant battery configurations for critical data integrity

Controllers Procurement Notes

Verify the specific suffix 'SN+' indicates the industrial temperature grade (-40°C to +85°C) and 16-pin SO package. Confirm RoHS compliance status as indicated by the '+' designation. Ensure compatibility with the target CMOS RAM's voltage requirements before procurement.

Controllers Selection Notes

Select this component when converting external CMOS SRAM to nonvolatile storage is required. Choose the SN+ variant specifically for industrial temperature environments. Verify that the system design accommodates the 16-pin SO footprint and supports the necessary battery connections for backup functionality.

Controllers Part Context

This part belongs to the DS1210 series of nonvolatile controllers manufactured by Analog Devices / Maxim Integrated. It is functionally similar to other variants like the DS1210S+ but distinguished by its extended industrial temperature rating and specific package configuration.

Controllers Replacement Considerations

Direct replacements include the DS1210N+ (8-pin PDIP, industrial temp) or DS1210S+ (16-pin SO, commercial temp). Verify pinout compatibility and thermal resistance differences when substituting packages.
