MAXIM INTEGRATED / ANALOG DEVICES DS1220AD100 Non-volatile SRAM
The DS1220AD-100+ is a 16K (16,384 bit) non-volatile static RAM (NVSRAM) in a 24-pin EDIP package. It features organized memory of 2,048 words by 8 bits each, and includes a self-contained lithium energy source with control circuitry that monitors the supply voltage (VCC) for out-of-tolerance conditions. In such events, the lithium battery is automatically activated to preserve data integrity, and write protection is enabled to prevent data corruption. The battery is electrically disconnected when not in use to maintain its freshness until the device is powered on. This NVSRAM can directly replace existing 2K x 8 SRAMs in 24-pin DIP packages, and its pinout matches 2716 EPROM and 2816 EEPROM devices for seamless substitution. It offers unlimited write cycles and requires no additional circuitry for microprocessor interfacing. Operating on a supply voltage range of 4.5V to 5.5V and functioning within 0°C to 70°C, it provides a minimum of 10 years data retention without external power. The device supports data protection during power loss, uses low-power CMOS technology, and has a read/write access time of 100ns. Write protection is enabled at a voltage of 4.37V, and the input/output capacitance is approximately 5pF.
