Working Principles

The IDT7164S20YI is a static random-access memory (SRAM) device. It stores digital information using flip-flops, which are electronic circuits capable of storing a single bit of data. The memory cells within the IC are organized in an 8K x 8-bit configuration, allowing for the storage of 8,192 bytes of data.

To read data from the memory, the appropriate address is provided on the address input pins (A0-A7), and the chip enable (CE) and output enable (OE) pins are activated. The requested data is then available on the data input/output pins (I/O0-I/O7).

To write data to the memory, the desired address is provided along with the data to be written. The chip enable (CE), write enable (WE), and output enable (OE) pins are activated accordingly. The data is then stored in the specified memory location.

Detailed Application Field Plans

The IDT7164S20YI is commonly used in various applications that require fast and reliable data storage and retrieval. Some of the potential application fields include:

1. Embedded Systems: Used as a primary or secondary memory in microcontrollers and other embedded systems.
2. Communication Equipment: Utilized for buffering and storing data in networking devices, routers, and modems.
3. Industrial Automation: Employed in control systems, PLCs (Programmable Logic Controllers), and robotics for data storage and processing.
4. Medical Devices: Integrated into medical equipment such as patient monitors, imaging systems, and diagnostic devices.
5. Automotive Electronics: Used in automotive applications like engine control units, infotainment systems, and advanced driver-assistance systems (ADAS).
