Additional Details:

The TC55257DTRL-85L is available in a variety of packages, including DIP and SOIC. The specific package type affects the overall dimensions and pinout of the device. This SRAM is commonly used in embedded systems and other applications where high performance and low power consumption are essential. The 85ns access time allows for rapid data retrieval, enhancing overall system responsiveness. The 'L' suffix typically indicates a low-power version of the SRAM.

The memory cell is designed to minimize its area and current consumption. The static design means that data is retained as long as power is applied, without the need for refresh cycles. This significantly simplifies the memory controller logic and reduces system overhead. It's used where fast and reliable data storage is needed, such as in networking equipment, industrial controllers, and various consumer electronics.
