The Microchip Technology 27HC256T-90-L is a 4Mbit CMOS One-Time Programmable (OTP) Read-Only Memory organized as 256K words by 16 bits. This asynchronous device offers a maximum access time of 90ns, facilitating high-speed data retrieval. Operating from a nominal supply voltage of 5V, it features a 3-state output characteristic for efficient bus interfacing. The component utilizes a PQCC32 package with a 1.27mm terminal pitch, suitable for surface-mount applications. Its robust construction is designed for operation within a temperature range of 0°C to 70°C. This memory solution is commonly employed in industrial control systems, legacy equipment, and embedded applications requiring non-volatile program storage. The 27HC256 series provides a reliable and cost-effective option for applications demanding specific memory configurations and access speeds.
