The DS1211S by Analog Devices / Maxim Integrated is a Nonvolatile Controller x 8 Chip designed to convert CMOS RAMs into nonvolatile memories. It features a voltage operating range of 4.75V to 5.5V and an operating temperature range of 0°C to 70°C.
This controller is housed in a 20-SOIC package, suitable for surface mount applications. It monitors incoming power for out-of-tolerance conditions, inhibiting chip enables for write protection and switching to battery power to maintain RAM data. The device consumes less than 100 nA of battery current and can test battery conditions on power-up.
Key features include automatic switching to battery during power-fail events, a 3-to-8 decoder for controlling up to eight CMOS RAMs, and the capability for redundant batteries. The power-fail signal can interrupt the processor during power failures. Optional 5% or 10% power-fail detection is available.
This component is ideal for applications requiring data retention in CMOS RAMs even during power interruptions. Its design ensures precise voltage detection with low battery consumption, making it a reliable solution for nonvolatile memory systems.
