The DS1210 from Analog Devices / Maxim Integrated is a CMOS controller chip designed to convert standard CMOS RAM into nonvolatile memory. It monitors incoming power and automatically switches to battery backup when the supply voltage drops out of tolerance, ensuring data integrity.
Key features include unconditional write protection when VCC is out-of-tolerance and automatic switching to battery power during power-fail events. The device consumes less than 100nA of battery current and includes a battery condition test on power-up. It offers optional 5% or 10% power-fail detection and a low forward voltage drop on the VCC switch.
Available in space-saving 8-pin PDIP or 16-pin SO packages, the DS1210 is suitable for applications requiring nonvolatile data storage. The 8-pin PDIP package measures 0.300 inches (7.62mm) and is designed for through-hole mounting.
This controller chip is ideal for systems where data retention is critical, such as data loggers, embedded systems, and point-of-sale devices. Its robust design ensures reliable operation by protecting against power fluctuations and providing battery backup.

The DS1210 operates within a voltage range of 4.75V to 5.5V.
The DS1210 has an operating temperature range of 0°C to 70°C.
The DS1210 is available in an 8-PDIP package.
When the incoming power supply (VCCI) goes out of tolerance, the DS1210 automatically switches to battery power to supply the RAM and inhibits chip enable to prevent writes.
The DS1210 consumes less than 100nA of battery current.
