Macronix in STMicroelectronics ecosystem

Macronix is a key partner of ST for non-volatile memories in the embedded market. Their portfolio helps to leverage the high potential of ST's products whenever an external non-volatile memory (NVM) is required.

Macronix NOR Flash products, OctaFlash memories, are on several STM32 evaluation boards or discovery kits to demonstrate the full capabilities of STM32 MCUs and MPUs. Macronix OctaBus Flash is often paired with STM32 to implement rich and smooth advanced graphics in Human Machine Interfaces (HMI) or to extend the code and data storage area.

Macronix automotive non-volatile memory products are enabling several applications based on ST’s products by providing the required top-notch level of quality and reliability from the memory side. Automotive Flash is needed for OTA or ST Stellar MCUs/MPUs families and processors such as Accordo and Telemaco. Macronix is also a key partner to provide NVM solutions for the TESEO GNSS family.
