Microchip Technology's 27HC256 is a 32K x 8 bit, CMOS One-Time Programmable (OTP) Read-Only Memory (ROM) device. Featuring a maximum access time of 55ns, this component operates asynchronously and offers common I/O with 3-state outputs. The 27HC256 series is designed for applications requiring non-volatile program storage, commonly found in industrial control systems, embedded computing, and legacy hardware designs. This particular variant, the 27HC256-55I-P, is supplied in a 28-lead PDIP (Plastic Dual In-line Package) with through-hole mounting. It operates within a temperature range of -40°C to +85°C and utilizes a supply voltage of 5V ±0.5V. The device requires a programming voltage of 13V.
