N28F256A150 – INTEL

The Intel N28F256A150 is a 256-kilobit (32K x 8) Flash memory device organized in a parallel architecture. Fabricated using non-volatile floating gate technology, it offers in-system electrical erasure and programming capabilities. The device features a 150ns access time, specified from address valid to data valid, suitable for applications requiring moderate read performance. It operates from a single 5V power supply and supports JEDEC standard byte-wide memory interfacing. Housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package, the N28F256A150 is designed for through-hole mounting on printed circuit boards. Key features include individual block locking for data protection and a command set facilitating sector erase and program operations. The device is typically employed in embedded systems for firmware storage, boot code, and data logging applications where non-volatility and moderate access speeds are required.
