Working Principles

The IDT71256L35YI is a static random access memory (SRAM) chip. It stores and retrieves digital data using a matrix of memory cells. The address inputs determine the location of the data to be accessed, while the write enable (/WE) and output enable (/OE) signals control the read and write operations. The data is stored in the memory cells as electrical charges, which can be quickly accessed and modified.

Detailed Application Field Plans

• Embedded Systems: Used in microcontrollers, industrial automation, and IoT devices for data storage and processing.
• Communication Systems: Employed in networking equipment, routers, and switches for buffering and caching purposes.
• Consumer Electronics: Integrated into gaming consoles, set-top boxes, and digital cameras for temporary data storage.

Alternative Models

• IDT71256SA15YI: 256 kilobit SRAM with a faster access time of 15 nanoseconds.
• IDT71256LA20YI: 256 kilobit SRAM with a lower power consumption of 20 milliwatts.
• IDT71256TA25YI: 256 kilobit SRAM with an extended operating temperature range of -55°C to +125°C.
