The CY7C263-25WC is a high-performance CMOS programmable logic device (PLD) from the CY7C263 family, designed for applications requiring reconfigurable digital logic. It typically features multiple input and output pins, providing flexibility in implementing custom logic circuits without the need for multiple discrete components. The "-25" in its name indicates a speed rating, denoting a 25ns maximum propagation delay, which is suitable for various digital applications requiring rapid processing speeds.
This device is usually packaged in a compact form factor, making it appropriate for space-constrained designs. The CY7C263-25WC is programmed using specialized hardware programmers, allowing designers to define and implement complex logic functions tailored to specific project requirements.
Applications for the CY7C263-25WC can range from simple logic gate replacements to more complex combinational and sequential logic designs in fields like telecommunications, consumer electronics, and industrial automation. As a member of the CMOS family, it offers advantages such as low power consumption and high noise immunity, contributing to reliable and efficient performance in a wide array of digital systems.

The CY7C263-25WC is housed in a 24-pin Windowed Ceramic Dual In-line Package (CerDIP). This type of package features a ceramic body with a transparent lid, allowing for exposure to ultraviolet light for erasing the EPROM content, if applicable.

The CY7C263-25WC is a 64K-bit PROM (Programmable Read-Only Memory) device developed by Cypress Semiconductor. It features a 16K x 4 organization, meaning it has 16,384 memory locations, each capable of storing 4 bits. This device has a 24-pin configuration.
The primary function of the CY7C263-25WC is to store data permanently, which can be used in various digital applications, including microcontroller systems, where non-volatile storage is required. Once programmed, the data remains intact even when the power is turned off. The device operates with a 5V supply voltage.
Key pins often include address lines, data lines, chip enable, and output enable, among others. The -25 in its designation indicates an access time of 25 nanoseconds, meaning it can quickly retrieve stored data, making it suitable for high-speed applications. This PROM is typically used in situations where data does not need to be frequently updated but requires reliable retention.

The CY7C263-25WC is manufactured by Cypress Semiconductor Corporation. Cypress Semiconductor is a technology company that specializes in designing and producing a wide range of semiconductor products, including memory chips, microcontrollers, and various types of integrated circuits.
