MYC-LMA35 System-On-Module

The MYC-LMA35 System-On-Module (SoM), a compact device measuring 37mm x 39mm, offers exceptional reliability for your upcoming embedded design projects. It's driven by the robust Nuvoton NuMicro® MA35D1 processor (MA35D16A887C), which boasts dual 64-bit Arm Cortex-A35 cores with speed up to 800 MHz, alongside a 180 MHz Arm Cortex-M4 core. This processor comes equipped with a BGA package incorporating 256MB DDR3L memory. The MYC-LMA35 SOM comes standard with either 256MB NAND Flash or 8GB eMMC storage, both of which be customized to suit your specific needs. A versatile 252-pin LGA expansion interface enables a wide range of peripheral and IO signals, maximizing the potential of the MA35D1 processor. With advanced and high-speed connectivity interfaces such as Gigabit Ethernet, SDIO3.0, USB 2.0 HS, and CAN FD, it is ideally suited for edge gateway and new energy applications. Additionally, the inclusion of an LCD display controller, a 2D graphics engine, and JPEG and H.264 decoders make it an excellent choice for HMI applications.
