High-Performance MXSMIO Flash Devices Now Compliant with ISO 26262 ASIL D Standard

HSINCHU, Jan. 5, 2026 /PRNewswire/ -- Macronix International Co., Ltd. (TSE: 2337), a leading integrated device manufacturer in the non-volatile memory (NVM) market, today announced the high-performance and efficiency MXSMIO™ family of flash memory has been expanded to include optimal-safety features for automotive applications. The MXSMIO flash devices, which feature multiple-I/O interfaces, are now compliant with the ISO 26262 ASIL D standard, requiring much higher levels of safety in vehicles' electronics.

Automotive Safety Integrity Level D (ASIL D) refers to the systems in vehicles that require current highest safety level. Many automotive-electronics applications come with high-risk functions, such as advanced driver assistance systems (ADAS), driver-monitoring systems and autonomous driving. ASIL D-compliant devices are designed to avoid those risks.

"Safety first; after that, all other necessities fall into place," said Roger Chen, safety manager at Macronix International. "The new MXSMIO members' primary focus – and this is something our automotive-electronics customers also prioritize – is safety, which we've 'baked into' the flash memory family. By now adhering to the ASIL D standard, we're ensuring automotive safety is addressed thoroughly and well in advance."

The MXSMIO family's ASIL D certification means that the flash memory is verified for the highest level of automotive safety as defined by ISO 26262 from the International Organization of Standards. ISO 26262 is an international standard with the title "Road Vehicles – Functional Safety." It was developed to ensure the safety of vehicles' electrical and electronic systems throughout their lifecycles, and to provide guidelines for designing those systems, including safety-related functions, processes, methods and tools.

The MXSMIO family provides two kinds of multi-I/O interfaces, giving designers broader flexibility in product development. The OctaFlash™  MX25/66_UM/LM/UW/LW series features the x8IO interface, whereas the QSPI MX25/66/U/L_G series uses a Quad I/O interface. The family's array of additional features includes:

• 3V or 1.8V operation for power efficiency
• OctaFlash or QSPI interface
• Error correction code (ECC) providing content protection
• Bus cyclic redundancy check (CRC), protecting data transmission during high frequency operation
• Real-time error correct signal and ECC/CRC status register, delivering error status to the host

Availability

The MX25/66_UM/LM/UW/LW and QSPI MX25/66/U/L_G series are available now. Please contact Macronix authorized representatives for pricing and volume information.

ArmorBoot MX76 Features Ultra-Fast Boot Times, High Performance, Integrated Authentication Protection, Data Integrity Verification, Secure Update, SPI Interface, Low-Power Options

HSINCHU, Aug. 6, 2025 /PRNewswire/ -- Macronix International Co., Ltd. (TSE: 2337), a leading integrated device manufacturer in the non-volatile memory (NVM) market, today announced ArmorBoot MX76, a robust NOR flash memory combining in a single device, the essential performance and an array of security features that deliver rapid boot times and iron-clad data protection. The newest member of Macronix's highly successful and widely deployed ArmorFlash™ family, ArmorBoot MX76 is a high-performance, highly secure flash memory designed for artificial intelligence (AI), Internet of Things (IoT), automotive electronics and other demanding applications that require ultra-fast boot times, integrated authentication protection, data integrity verification, secure flash updates, a Serial Peripheral Interface (SPI), power options of 3V or 1.8V, and capacities up to 1 Gb.

"We developed ArmorBoot MX76 to address specific challenges designers in the AI, IoT and automotive-electronics markets face: achieving fast boot times, enhanced security and seamless updates," said F.L. Ni, vice president of marketing at Macronix International. "Those, along with other rapidly growing markets – industrial automation, healthcare and wireless communications, for example -- represent broad spectrum of system and device manufacturers demanding the greater performance and heightened security that ArmorBoot MX76 provides. In an age when cybersecurity is no longer a luxury but a necessity, and boot times are increasingly consequential to products' success, Macronix is delivering the highest level of security and performance in flash memory."

ArmorBoot MX76's unique architecture sets it apart from previous secure NOR flash solutions in that it combines in-demand performance and security functions in a single device; no additional chips are needed to ensure required levels of data protection. During a system's critical startup or update phase, the memory's performance and security features kick in automatically and seamlessly. In addition to being a single-device solution for ultra-fast booting and robust security, ArmorBoot MX76's SPI interface enables smooth integration into new or existing systems.

Top worldwide manufacturers who've already designed ArmorFlash memories into their AI, IoT and automotive-focused solutions are presently evaluating ArmorBoot to expand their product portfolios to offer enhanced performance and secure-boot capabilities.
