IDT71V256SA20YGI is a specific type of integrated circuit, from the industrial giant IDT. It is a memory device, specifically a 256K x 16 -bit high-speed static RAM. It manifests itself as a 28-pin, 32-pin, and 44-pin DIP (dual inline package) as well as ball grid array and ceramic leadless chip carrier packages.

Application Field:

IDT71V256SA20YGI is highly suitable for buffer and data caching tasks in technical applications. It is designed to fit applications that require repetitive high-band memory fetch, such as those found in graphics workstations, and certain classes of microprocessor-based systems, like embedded systems and other consumer electronics.

Working Principle:

The basic working principle of the IDT71V256SA20YGI is simple. It consists of 256K x 16-bit of RAM. The RAM is used as a buffer to store data, which is to be processed subsequently. This data can be retrieved from the buffer RAM whenever required, resulting in a reduced memory latency and an increased memory bandwidth. Data can be stored into and retrieved from the RAM in two distinct ways - through asynchronous and synchronous access.

Synchronous access requires a clock signal to deliver data to the RAM. It is used for applications where data must be obtained through high-speed operations, such as graphics workstations. Asynchronous access allows data to be written and retrieved from the RAM without the need for a clock signal. It is ideal for applications where low-speed operations are required, such as embedded systems and consumer electronics.

The IDT71V256SA20YGI is designed to make sure that data fetched at high-speed will be delivered without errors. It is equipped with a multiple cycle burst capability that allows data to be sent and retrieved from the RAM in a series of short bursts, thus reducing the cycle time. Furthermore, it runs on a low power supply voltage, making it an efficient and viable solution for many applications operating on limited power sources.

The IDT71V256SA20YGI uses a variety of sets of control signals to read, write and reset the RAM. It also has built-in error protection and fault tolerant functions that can detect and correct any errors caused by electrical or mechanical disturbances. This ensures that data is accurate and reliable at all times.
