MYIR Unveils i.MX91-Based SOM to Power Next-Gen Smart Devices

Shenzhen, China – MYIR today announces the launch of its latest embedded computing solution, the MYC-LMX91 System-on-Module (SoM), powered by NXP’s energy-efficient i.MX 91 processor. This compact, high-performance module maintains full pin compatibility with MYIR’s existing MYC-LMX9X (i.MX93) series, allows customers to scale their designs without hardware redesigns.

The MYC-LMX91 features a compact design, measuring just 37mm by 39mm, and utilizes the i.MX 91 Cortex-A55 MPU. It comes equipped with 1GB LPDDR4 RAM, 8GB eMMC storage, 32KB EEPROM, and a Power Management IC (PMIC), providing a solid foundation for your next embedded project. Leveraging the the full potential of the i.MX 91 SoC, the MYC-LMX91 supports a diverse range of peripherals, including 2x USB 2.0, 2x Gigabit Ethernet, 2x CAN-FD interfaces, 8x UART, 8x SPI, and RGB display interfaces, through a 218-pin LGA expansion interface. It is capable of running the Linux Operating System, making it perfect for applications such as EV Charging Stations, HMIs, Smart Home & Building Automation, Industrial Gateways, and Medical Platforms.
