  • Description

    The CY7C263-55WMB is a high-performance 8192-word by 8-bit CMOS PROM, which is a reprogrammable integrated circuit chip. It is equipped with an erasure window which allows the chip to be erased using UV light and then reprogrammed. The memory cells in the chip utilize EPROM floating-gate technology and byte-wide intelligent programming algorithms. The CY7C263-55WMB is available in two different package sizes: 300-mil-wide and 600-mil-wide. Unlike the CY7C261, the CY7C263-55WMB does not power down when deselected.
