Microchip Technology's 27HC256L-55I-SP is a 32,768-word by 8-bit (256 Kbit) CMOS One-Time Programmable (OTP) ROM. This asynchronous memory device features a maximum access time of 55ns and operates from a nominal 5V supply. The 27HC256 series is designed for applications requiring reliable, non-volatile program storage. Its 8-bit parallel interface and 3-state outputs facilitate integration into various system architectures. The component is housed in a 28-lead PDIP package with through-hole mounting, a standard 2.54mm terminal pitch, and an operating temperature range of -40°C to +85°C. Applications for this OTP ROM include embedded systems, industrial control, and legacy equipment where stable code storage is essential.
