Microchip Technology 27HC191L-45-K is a 16Kb (2K x 8) CMOS UVPROM memory device. This component features a 45ns maximum access time and operates from a 4.5V to 5.5V supply, with a nominal 5V operation. The memory organization is 2K words by 8 bits, providing a 16-bit data bus. It utilizes asynchronous operation and offers 3-state outputs. The device is packaged in a 28-lead Ceramic Quad Flat Pack (CQFP) with a window for UV erasure. Applications for this type of non-volatile memory include industrial control systems and legacy equipment requiring robust, reprogrammable storage. The 27HC191 series UVPROM is designed for applications demanding reliable data retention and reprogrammability.
