Featured Products

MT25Q: Enhanced SPI Multiple I/O Solutions

See Products

Enhance read, erase, and program performance in your designs with our cost-effective 45nm MT25Q SPI NOR Flash devices—ideal for set-top boxes (STBs), networking infrastructure equipment (routers), industrial applications, and other embedded designs. The MT25Q enables you to read 512Mb of code in less than one second, perform sector erases dramatically faster than previous-generation devices, and program at industry-leading speeds of up to 2 MB/s.

N25Q: SPI Multi I/O Solutions

See Products

Our multi-I/O (single, dual, and quad) serial NOR line offers dramatic read performance (up to 54 MB/s), flexible memory partitioning (uniform 64KB and 4KB), small package size, and wide package support. Based on 65nm technology, N25Q is offered in both 1.8V and 3V power supplies, as well as an automotive-grade option. N25Q is compatible with the M25P and M25PX families.

RPMC N25Q: Improve Security for Ultrathins With Monotonic Counter Feature

See Products

We’ve partnered with Intel to provide one of the most advanced SPI NOR devices in the market. Our cost-effective 64Mb N25Q device with the replay-protected monotonic counter (RPMC) feature meets the security requirements of your ultrathin applications and is validated for future Intel® Ultrabook™ platforms.

M45PE/M25PE: Single I/O, Legacy SPI Page Erase

See Products

Our M45PE/M25PE serial NOR line offers a standard SPI protocol (up to 9 MB/s), page erase (uniform 256 bytes, 4KB, and 64KB), support for lower densities (<32Mb), and EEPROM command emulation. Each 256-byte page can be individually erased and programmed, with a write instruction that offers the ability to update data at the byte level. M45PE and M25PE are compatible with the M25P and M25PX families.

M25P: Legacy SPI Single I/O

See Products

The M25P series is legacy SPI family offers standard SPI protocol (9MB/sec max), sector erase (uniform 64kB), small package size—enabling even smaller PCB designs, low density support (<32Mb). The M25P line also features an automotive grade option.

M25PX: Legacy SPI Single I/O

See Products

Our dual-I/O (single and dual) serial NOR line offers high read performance (up to 19 MB/s), flexible memory partitioning (uniform 64KB and 4KB), and support for lower densities (<32Mb). M25PX delivers improved read speed compared to legacy M25P devices over the entire supply voltage range and also offers an extended temperature range, as well as an automotive-grade option. M25PX is compatible with the M25P family.
