1024k NV SRAM with Phantom Clock
The DS1248Y-70 is a nonvolatile static RAM (NVRAM) manufactured by Dallas Semiconductor. It is a 32-pin DIP package with a capacity of 8K x 8 bits. The DS1248Y-70 is a low-power NVRAM that combines the features of a static RAM and a nonvolatile memory. It is designed to retain data for an extended period of time, even when power is removed. The device is powered by a lithium battery, which is connected to the chip's VCC pin. The battery provides power to the chip during power-off periods, allowing the data stored in the chip to remain intact. The DS1248Y-70 is ideal for applications that require data to be retained for long periods of time, such as industrial controllers, medical equipment, and security systems. It is also suitable for applications that require frequent data updates, such as data logging, instrumentation, and process control.
