The DS1213C is a nonvolatile memory chip manufactured by Dallas Semiconductor. It is a 28-pin DIP (dual in-line package) device that is used to store data in a nonvolatile manner. The DS1213C is a 2Kb CMOS static RAM (SRAM) with a built-in nonvolatile controller. The controller is used to store the contents of the SRAM in a nonvolatile manner, allowing the data to be retained even when power is removed from the device. The device also features a built-in watchdog timer, which can be used to reset the device if it becomes unresponsive. The DS1213C is commonly used in applications such as industrial control systems, automotive systems, and medical devices. It is also used in embedded systems, where it can be used to store configuration data or other data that needs to be retained even when power is removed. (For reference only)
