Microchip Technology 27C256-17B-UA is a 32768 word by 8-bit (32K x 8) electrically programmable read-only memory (EPROM) device. This CMOS component features a maximum access time of 170ns, enabling efficient data retrieval. The 27C256 series offers a common I/O type and 3-state output characteristics. Encased in a 32-terminal ceramic chip carrier (CQCC32) package with a rectangular shape and quad terminal positions, it is designed for surface mounting. The device operates asynchronously with a nominal supply voltage of 5V and boasts a wide operating temperature range from -55°C to +125°C. Applications for this component span industrial control systems, telecommunications infrastructure, and legacy system upgrades where reliable, non-volatile program storage is critical. Its robust construction and adherence to military screening standards (38535Q/M; 38534H; 883B) underscore its suitability for demanding environments.
