DS1244Y-70, 256Kbit (32K x 8) Nonvolatile SRAM with Phantom Real-Time Clock, EDIP-28

The DS1244Y-70 is a 256Kbit (32K x 8) Non-Volatile SRAM (NV SRAM) with an embedded Phantom Clock, designed for applications requiring fast, battery-backed memory with integrated real-time clock functionality. This DIP-28 packaged device is an ideal solution for industrial control, telecommunications, automotive, and embedded systems where secure data retention and real-time tracking are essential.

The Phantom Clock provides timekeeping for hundredths of seconds, minutes, hours, days, months, and years, with automatic leap year correction up to the year 2100. It operates in either 12-hour or 24-hour format, ensuring flexibility for various system designs.

The embedded lithium energy cell guarantees over 10 years of data retention and seamless transition between power loss and normal operation. The memory and real-time clock operate transparently, preventing data corruption during power failures.

The DS1244Y-70 supports high-speed 70ns access times, making it suitable for demanding applications. The device functions as a drop-in replacement for conventional SRAM, requiring no additional circuitry for data retention or clock operation.

Available in a DIP-28 package, the DS1244Y-70 is JEDEC standard compliant, making it an excellent choice for legacy computers, industrial automation, data logging, and security systems.
