The Microchip Technology 27HC64-70-K is a 65536-bit (8K x 8) CMOS ultraviolet erasable programmable read-only memory (UVPROM). This component offers a maximum access time of 70ns, enabled by its high-speed CMOS technology. Featuring a parallel interface with common I/O, it operates asynchronously and provides 3-state output characteristics. The device is housed in a 32-terminal ceramic leadless chip carrier (CQCC32) package with a window for UV erasure. Typical applications include firmware storage and data buffering in industrial automation, telecommunications infrastructure, and legacy system upgrades where non-volatile, reprogrammable memory is required. The 27HC64 series utilizes a 5V supply and supports a programming voltage of 12.5V.
