The Context: With their enhanced performance — including fast read performance up to 104MHz;  fast program and erase times down to 1.1ms and 2.6ms, respectively; maximum erase/program currents down to 1.3mA; and maximum read currents down to 3.7mA at 104MHz — Alliance Memory’s new 4Mb and 16Mb 3V multiple input/output serial NOR flash memory products are designed to meet the demands of the computer, consumer, communications, and IoT markets. The 4Mb AS25F304MD-10S1IN offers support for single and dual SPI operation, while the 16Mb AS25F316MQ-10S1IN adds support for the quad SPI mode. Both devices provide reliable, long-term performance with 100,000 program/erase cycles and 20-year data retention.

The flash memory products support uniform 4KB or 32KB or 64KB erase and feature program/erase suspend and resume. The AS25F316MQ-10S1IN also offers an 8/16/32/64byte 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.

Availability: Samples and production quantities of the 3V serial NOR flash memory products are available now, with lead times of 8 to 12 weeks.
