MAXIM INTEGRATED / ANALOG DEVICES DS1225AB70IND Non-volatile SRAM
The DS1225AB-70IND+ from Maxim Integrated is a 64K non-volatile SRAM housed in a 28-pin EDIP package. It features 65,536 bits organized as 8,192 words of 8 bits each. This SRAM includes a built-in lithium energy source and control circuitry that monitors VCC voltage, automatically switching on the power source and enabling write protection during voltage out-of-tolerance conditions to prevent data loss. It can replace standard 8K x 8 SRAMs, EPROMs, or EEPROMs with a compatible pinout, offering improved performance without additional interface circuitry. The device supports unlimited write cycles, operates from 4.75V to 5.25V, and functions reliably in temperatures from -40°C to +85°C. It provides fast access times of 70ns, uses low power CMOS technology, and automatically protects data during power interruptions. The lithium battery remains disconnected until first power-up, ensuring data freshness. Key features include automatic power-fail safeguard, no restrictions on write cycles, and simple microprocessor interfacing.
