New series of 3V multiple I/O serial NOR flash memory solutions

29-10-2021 | Alliance Memory | Semiconductors

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


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


The series devices support uniform 4KB or 32KB or 64KB erase, provide an 8/16/32/64byte wrap-around burst read mode, and offer program/erase suspend and resume. Advanced security features comprise block protection and 4K-bit secured OTP to protect content from hostile access and accidental programming and erasing.


With enhanced performance, the serial NOR flash memory products are intended to satisfy the demands of the computer, consumer, IoT, communications, and mobile markets. The devices are ideal for employment in chipsets for PCs, DVD and Blu-ray players, digital cameras, handheld GPS units, wireless LANs and cable modems, printers, LCDs, set-top boxes, mobile and wearable devices, smart meters, and more.
