The CY27C256-120JC is a high-performance, 256Kbit Electrically Programmable Read-Only Memory (EPROM) component designed and manufactured by Cypress. This component is particularly notable for its parallel interface, enabling rapid data access and manipulation. It comes packaged in a 32-pin Plastic Leaded Chip Carrier (PLCC), ensuring reliable connectivity and ease of integration into circuit designs. The device operates efficiently with a 120ns access time, a feature that enhances its suitability for high-speed microprocessor systems. Its storage capacity and quick access time make it an excellent choice for storing firmware or application code in a variety of electronic devices, ranging from automotive systems to industrial controls. As a product manufactured by Cypress, now part of Infineon following a strategic acquisition, the CY27C256-120JC benefits from the robust quality assurance processes and innovative technology development for which the brand is known. This makes it a reliable and durable choice for designers and engineers looking for memory solutions that require minimal power and offer substantial data retention capabilities.
