DS1210S Description

Short technical summary and product information.

The DS1210S from Dallas Semiconductor is a CMOS nonvolatile controller chip that enables the conversion of standard CMOS RAM into nonvolatile memory. This functionality is crucial for applications requiring data retention even when primary power is lost.

The chip monitors incoming power and automatically switches to battery backup when a power-fail condition is detected. This ensures uninterrupted power to the RAM, preventing data corruption. It features unconditional write protection when VCC is out-of-tolerance, safeguarding data integrity during power fluctuations.

Key features include extremely low battery current consumption of less than 100nA, making it suitable for battery-powered applications. It also offers optional power-fail detection at 5% or 10% tolerance and an optional industrial temperature range of -40°C to +85°C for demanding environments. The DS1210S is available in space-saving 8-pin PDIP or 16-pin SO packages, facilitating integration into various PCB designs.

By combining the DS1210S with a CMOS memory and batteries, designers can achieve reliable nonvolatile RAM operation. The low forward voltage drop on the VCC switch and the ability to test battery condition on power-up further enhance its utility in embedded systems.
