MAXIM INTEGRATED / ANALOG DEVICES DS1220AB200 Nonvolatile SRAM
The DS1220AB-200+ is a 16K (16,384-bit) non-volatile SRAM enclosed in a 24-pin EDIP package. It features a fully static organization of 2,048 words by 8 bits. Incorporating an integrated lithium energy source and control circuitry, it monitors VCC for out-of-tolerance conditions and automatically switches on the battery backup, enabling write protection to secure data. The lithium source remains disconnected until power is first applied, conserving battery life. Compatible with standard 2K x 8 SRAMs, it matches the pinouts of 2716 EPROM and 2816 EEPROM chips, supporting unlimited write cycles without extra circuitry, ideal for microprocessor systems needing high data retention reliability.
