Product details

What the MXD1210CPA+ does on the board

The MXD1210CPA+ is a Nonvolatile RAM controller — it manages the transition between main system power and a backup battery for standard SRAM, converting it into nonvolatile memory that retains data when the main supply drops.

Supply, temperature, and package fit

Housed in an 8-DIP (0.300", 7.62mm) through-hole package with a 8-PDIP supplier device package designation, it mounts directly into a standard 0.300-inch wide DIP socket or solders into plated through-holes on a PCB.

Frequently asked questions

Does the MXD1210CPA+ require an external battery?

Yes — the controller manages the switchover to an external backup battery (typically a lithium coin cell or a capacitor) but does not include one on-chip. The battery connects to the controller's VBAT pin, and the controller gates it to the SRAM when the main supply drops below the threshold.

What is the difference between MXD1210CPA+ and DS1210?

The MXD1210CPA+ and the DS1210 are functionally equivalent Nonvolatile RAM controllers from the same design family. Both monitor a 5 V supply rail, write-protect the SRAM, and switch to battery backup on power loss. The MXD1210CPA+ is the Analog Devices-branded version in an 8-DIP package; the DS1210 was originally a Dallas Semiconductor part. The pinout and basic operating principle are the same, but the MXD1210CPA+ carries Analog Devices' current active-production status and ROHS3 compliance.
