Alliance Memory AS25F Serial NOR Flash Memory

Alliance Memory AS25F Serial NOR Flash Memory combines fast read performance up to 133MHz with fast program and erase times. Available in 8-pin SOP Wide Body (209mils) and 8L WSON (6.0mm x 5.0mm) packages, the devices operate from a single 1.6V to 3.6V power supply over an industrial temperature range of -40°C to +85°C. The solutions offer support for single, dual, and quad SPI modes, and provide reliable, long-term performance with 100,000 program/erase cycles and 10-year data retention. Alliance Memory AS25F Serial NOR Flash Memory supports uniform 4KB or 32KB, or 64KB erase, offers an 8/16/32/64byte wrap-around burst read mode, and features program/erase suspend and resume. Advanced security features include block protection and 4K-bit secured OTP to protect content from hostile access and inadvertent programming and erasing.

With enhanced performance, the AS25F series is designed to meet the demands of the computer, consumer, communications, IoT, and mobile markets. These devices are ideal for use in PCs, wireless LANs and cable modems, printers, set-top boxes, LCD displays, mobile and wearable devices, digital cameras, handheld GPS units, smart meters, and more.
