Analog Devices Inc. DS1645AB-85 is a 128K x 8 non-volatile static random-access memory (SRAM) device. This CMOS component offers an access time of 85 ns and operates from a 5V supply. The DS1645 series memory utilizes a battery-backed SRAM with a built-in Real-Time Clock (RTC) and a lithium energy source, providing data retention without external power. It is packaged in a 32-lead PDIP (Plastic Dual In-line Package) with through-hole termination. This device is suitable for applications requiring persistent data storage and timekeeping, commonly found in industrial control systems, metering, and data logging equipment. The memory organization is 131,072 words by 8 bits.
