Microchip Technology's 27HC291 series UVPROM, part number 27HC291-55I-SJ, offers a 16Kb memory density organized as 2K words by 8 bits. This CMOS device features a maximum access time of 55ns and operates asynchronously. The 24-pin ceramic dual in-line package (CDIP24) with a window facilitates in-system reprogramming via UV erasure. Designed for industrial temperature ranges from -40°C to +85°C, it operates from a nominal 5V supply, with a range of 4.5V to 5.5V. Applications for this component are found in industrial control systems, legacy equipment, and embedded systems requiring non-volatile program storage. The 27HC291-55I-SJ utilizes through-hole mounting and has common I/O characteristics with 3-state outputs.
