15 November 2023

Alliance Memory has expanded its offering of 3 V multiple input/output serial NOR flash memory products with new 4 Mb and 16 Mb devices in the SOP8 narrow body (150 mils) package. The 4 Mb AS25F304MD-10S1IN and 16 Mb AS25F316MQ-10S1IN combine fast read performance up to 104 MHz with fast program and erase times down to 1.1 ms and 2.6 ms, respectively.

The devices operate from a single 2.7 V to 3.6 V power supply over an industrial temperature range of -40° C to 85° C. The AS25F304MD-10S1IN offers support for single and dual serial peripheral interface (SPI) operation, while the AS25F316MQ-10S1IN adds support for the quad SPI mode. The solutions offer maximum erase/program currents down to 1.3 mA and maximum read currents down to 3.7 mA at 104 MHz, and they provide reliable, long-term performance with 100,000 program/erase cycles and 20-yearSource: Alliance MemorySource: Alliance Memory data retention.

The devices support uniform 4 KB or 32 KB or 64 KB erase and feature program/erase suspend and resume. The AS25F316MQ-10S1IN also offers an 8/16/32/64 byte wrap-around burst read mode. Advanced security features include block protection, 128-bit unique ID for each device, a discoverable parameters (SFDP) register, 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 and internet of things markets. The devices are ideal for use in chipsets for hard drives, DVD and Blu-ray players, wireless LANs and cable modems, printers, set-top boxes, LCD displays, digital cameras, Bluetooth devices, handheld GPS units, smart meters and more.

Samples and production quantities of the 3 V serial NOR flash memory products are available now, with lead times of 8 to 12 weeks. Pricing for U.S. delivery starts at $0.80 for the AS25F304MD-10S1IN and $0.90 for the AS25F316MQ-10S1IN.
