Microchip Technology presents the 27HC64, a CMOS UVPROM with an 8K x 8 memory organization and a fast 45ns access time. This component, part number 27HC64-45-J, is housed in a 28-lead Ceramic Dual In-line Package (CDIP28) with a glass-sealed window for ultraviolet erasure. It features common I/O and 3-state outputs, operating asynchronously from a 4.5V to 5.5V supply. The 27HC64 series is well-suited for applications requiring reliable, non-volatile program storage, including industrial control systems, legacy computing platforms, and specialized test equipment where robust data retention and straightforward interfacing are critical design considerations. The through-hole terminal form factor and standard DIP package facilitate integration into established circuit designs.
