MAXIM INTEGRATED / ANALOG DEVICES DS1225AD85 Nonvolatile SRAM
The DS1225AD-85+ is a 64K non-volatile SRAM in a 28-pin EDIP package. It provides 65,536 bits organized as 8,192 words by 8 bits. This fully static SRAM features an integrated lithium energy source and control circuitry that monitors VCC voltage. If a power loss is detected, the lithium battery automatically switches on to preserve data and enables write protection to prevent corruption. The device is compatible with standard 8K x 8 SRAM, replacing 8K x 8 static RAM or EEPROM in the same pinout, such as 2764 EPROM and 2864 EEPROM, facilitating seamless integration and improved performance. It supports unlimited write cycles without additional support circuitry for microprocessor interfacing. The SRAM operates with a supply voltage from 4.5V to 5.5V and a temperature range of 0°C to 70°C. It ensures data protection during power outages, offers read and write access times of 85ns, and employs low power CMOS technology. The lithium energy source remains disconnected until first use, maintaining freshness during storage. Ideal for embedded system design and development, this device provides reliable non-volatile memory storage with automatic data protection features.
