Hardware Specification

The MYC-LD25X System-on-Module (SOM) mounted on the MYD-LD25X Development Board uses the 14 x 14mm, 0.5mm ball pitch, 424-ball VFBGA packaged 1.5 GHz ST STM32MP257D microprocessor (STM32MP257DAK3). This processor belongs to the ST STM32MP25xA/D product line, which features a dual-core Arm Cortex-A35 (operating at up to 1.5 GHz) and a single-core Arm Cortex-M33 (running at up to 400 MHz). Additionally, it includes a neural processing unit (NPU) with 1.35 TOPS and a 3D graphics processing unit (GPU). The processor is further enhanced with an integrated video encoder and decoder. A rich set of interfaces is supported by the processor, such as three Ethernet ports with switch and TSN capabilities, FD-CAN, PCIe/USB3.0, and others. It also supports Parallel and MIPI CSI-2 for camera connections and Parallel, LVDS, and MIPI DSI for display connectivity. These features make STM32MP25xA/D devices well-suited for a wide range of consumer, industrial, white goods and medical applications.
