Working Principles

The IDT7164S20TP is a static RAM chip that stores and retrieves digital data. It operates by using an address bus to select a specific memory location and read or write data to/from that location. The chip is enabled by the CE (Chip Enable) pin, and the OE (Output Enable) and WE (Write Enable) pins control the direction of data flow.

When the CE pin is active and the OE pin is enabled, the chip outputs the data stored at the selected memory location onto the data bus. Conversely, when the CE and WE pins are active, data from the data bus is written into the selected memory location.

Detailed Application Field Plans

The IDT7164S20TP can be used in various applications that require random access memory, such as:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Communication devices
4. Industrial automation systems
5. Medical equipment
6. Automotive electronics
