DS1248Y-70+ Description

Short technical summary and product information.

The DS1248Y-70+ is a 1024K NV SRAM with a phantom clock, organized as 128K words by 8 bits, featuring a built-in real-time clock. It includes an embedded lithium energy cell that maintains calendar operation and retains RAM data, even in the absence of power, offering over 10 years of data retention.

 

This component operates with a voltage supply range of 4.5V to 5.5V and consumes a maximum of 10mA at 5V for timekeeping. It features a parallel interface and supports both HH:MM:SS:hh (12/24 hr) time formats and YY-MM-DD-dd date formats. The device is designed for through-hole mounting and comes in a 32-EDIP package.

 

Key features include automatic leap year compensation valid up to 2100 and a watch function that is transparent to RAM operation. The DS1248Y-70+ is UL recognized and is suitable for applications requiring reliable timekeeping and non-volatile data storage.
