Analog Devices Inc. DS1645AB-120 is a 128K x 8 Non-Volatile SRAM featuring 120ns access time. This CMOS device, available in a 32-pin PDIP package (R-PDIP-T32), integrates battery-backed data retention capabilities within a standard SRAM interface. The DS1645 series offers a robust solution for applications requiring persistent data storage without the overhead of external battery management circuitry for basic operation. Its 1,048,576 bit density and 131,072 word count are suitable for industrial control, data logging, and embedded systems where data integrity is critical. The component operates within a 0°C to 70°C temperature range and utilizes a 5V supply voltage. The through-hole mounting, dual in-line package with a 2.54mm terminal pitch, facilitates integration into legacy and through-hole PCB designs. Typical applications include telecommunications, medical equipment, and point-of-sale systems.
