The SMARC-iMX8M offers high-performance processing for a low-power System-on-Module. It perfectly fits various embedded products, the growing market of connected and portable devices and segment for connected streaming audio/video devices, scanning/imaging devices and various devices requiring high performance but low-power applications.
The product is based on the NXP i.MX8M Dual/Quad Lite/Quad family of multi-purpose processors, featuring an ARMR CortexTM-A53 up to 1.5GHz with an additional 266MHz ARM Cortex-M4 core.
This heterogeneous multicore processing architecture enables the device to run an open operating system like Linux on the Cortex‚ÄźA53 core and an RTOS like FreeRTOSTM on the Cortex-M4 core for time and security critical tasks. The module connector has 314 edge fingers that mate with a low profile 314 pin 0.5mm pitch right angle connector.
Featuring NXP's i.MX8M System-on-Chip, Embedian's SMARC-iMX8M offers single- or dual-channel 18-bit/24-bit LVDS LCD, Gigabit Ethernet, HDMI/DP, SDHC, USB 2.0, USB USB 3.0, UARTs, CAN bus, PCIe and many peripheralinterfaces in a cost effective, low power, miniature package. Embedian's SMARC-iMX8M thin and robust design makes it an ideal building block for reliable system design with a wide range of products in target markets requiring high-performance processing with low power consumption, compact size and a cost-effective solution.
The SMARC-iMX8M is also a 100% SMARC 2.0 specification compliant module from Embedian.
