About Macronix
Founded in 1989 and headquartered in Hsinchu, Taiwan, Macronix International Co., Ltd. operates its own 12-inch wafer fabrication facility and specializes in non-volatile memory technology. Macronix holds a significant global market share in serial NOR flash and has expanded into specialty NAND, 3D NAND, and innovative memory architectures.
Macronix's serial NOR flash (MX25L and MX25U series) covers densities from 512Kb to 2Gb with SPI, Dual-SPI, Quad-SPI, and OctaFlash (Octal DTR) interfaces — the fastest serial NOR solutions available for XIP (execute-in-place) applications. ArmorFlash (MX75 series) integrates hardware authentication, encrypted read/write, and monotonic counters for secure ADAS and automotive gateway firmware. The company also produces SLC NAND flash (MX30LF/MX35LF) for embedded storage in routers, set-top boxes, and industrial controllers.
