Additional Details:

The CY7C167-25PC operates at a supply voltage of 5V. It has separate data input and output pins, allowing for simultaneous read and write operations. The device is available in a 28-pin DIP package. It is commonly used in applications requiring high-speed memory access, such as cache memory in microprocessors and controllers. Rochester Electronics continues to supply this device, ensuring availability for legacy systems and new designs where this technology is still suitable. The operating temperature for the industrial version is from -40C to +85C.

The fast access time of this SRAM makes it ideal for applications that require immediate data retrieval, such as real-time data processing, signal processing, and high-speed buffering. The single-bit-wide organization is appropriate for applications where data is processed one bit at a time, such as digital signal processing. The low power consumption makes it suitable for battery-powered devices and other power-sensitive applications.
