Microchip Technology's 27HC191 series OTP ROM, part number 27HC191-55I-P, offers a 2048 x 8 memory organization with a maximum access time of 55ns. This CMOS device operates asynchronously and features 3-state outputs, suitable for applications requiring dedicated firmware storage. The component utilizes a PDIP24 package with through-hole mounting and a standard 2.54mm terminal pitch. Its operating temperature range spans from -40°C to +85°C, and it requires a supply voltage between 4.5V and 5.5V. Applications for this type of non-volatile memory can be found in industrial control systems, legacy equipment, and embedded designs where program code or lookup tables are permanently stored. The 27HC191-55I-P is designed for robust performance in demanding environments.
