Microchip Technology's 27HC256T-90I-SO is a 1 Megabit (1Mx8) CMOS One-Time Programmable (OTP) ROM. This device offers an asynchronous access time of 110ns and operates from a nominal 3.3V supply. The 27HC256 series is designed for applications requiring reliable, non-volatile data storage. Its 8-bit output width and parallel interface are suitable for various embedded systems. The component is housed in a 28-lead PDSO (Plastic Dual Small Outline) package with a 1.27mm terminal pitch. Operating over an industrial temperature range of -40°C to +85°C, this OTP ROM finds utility in industrial control, consumer electronics, and automotive applications where fixed program code or data is essential. The 3-state output characteristic allows for bus-sharing configurations.
