Additional Details

The LH52256N-70L is often found in applications where battery life or low power consumption is a critical design parameter. The "-70L" suffix typically indicates the access time and package type. SRAMs like this offer a good balance between speed, power consumption, and cost, making them a popular choice for a wide range of digital systems. Data is retained as long as the chip is powered. Package types can vary (e.g., DIP, SOJ), so physical dimensions need to be confirmed with a datasheet before integrating the component into a design.
