Microchip Technology's 27HC256-90I-SP is a 4096-bit (1K x 4) CMOS One-Time Programmable (OTP) ROM. Featuring a fast 45ns access time, this component is organized as 1K words, each 4 bits wide. It operates asynchronously with a nominal supply voltage of 5V. The 27HC256-90I-SP is housed in a 28-lead PDIP package with through-hole mounting and a 2.54mm terminal pitch. Its operating temperature range is -40°C to +85°C, making it suitable for industrial applications. This device is commonly found in legacy systems, automotive controls, and industrial automation where fixed program storage is required. The 3-state outputs and parallel interface streamline integration into existing designs.
