Alliance Memory Introduces New Series of 3V Multiple I/O Serial NOR Flash Memory Solutions


AS25F Series Devices Provide Supply Continuity for Micron Technology’s Discontinued N25Q Line

Alliance Memory today announced a new line of 3V multiple input/output serial NOR flash memory products designed to provide supply continuity for Micron Technology customers utilizing discontinued N25Q series devices. Offering support for single, dual, and quad SPI modes, the AS25F series combines fast read performance up to 104MHz with fast program and erase times of 0.3ms and 40ms typical, respectively.

Available in 8-pin SOP Wide Body (209mils) and 8L WSON (6x5mm) packages, the devices released today operate from a single 2.7V to 3.6V power supply over an industrial temperature range of -40°C to +85°C. The solutions offer typical erase/program currents of 20mA and maximum read currents of 25mA at 104MHz, and they provide reliable, long-term performance with 100,000 program/erase cycles and 10-year data retention.

AS25F series devices support uniform 4KB or 32KB or 64KB erase, offer an 8/16/32/64byte wrap-around burst read mode, and feature 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 their enhanced performance, the serial NOR flash memory products are designed to meet the demands of the computer, consumer, communications, IoT, and mobile markets. The devices are ideal for use in chipsets for PCs, DVD and Blu-ray players, wireless LANs and cable modems, printers, set-top boxes, LCD displays, mobile and wearable devices, digital cameras, handheld GPS units, smart meters, and more.
