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.

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.
