As we all know, NXP has introduced iMX8 chips for a long time. There are more and more iMX8 families, and there are iMX8, iMX8M, iMX8M Mini and i.MX8M Nano4 chip application processors at present. Recently, I have taken time to understand the core board and development board of Mir Electronics iMX8 series. Now I would like to share the information of these two card chips:

Introduction of i.MX8M Chip

(Mir MYC-JX8MX core board and development board design chip)

NXP's i.MX8M family of application processors are based on Arm ®Cortex ®- A53 and Cortex-M4 cores with industry-leading audio, voice and video processing capabilities for a wide range of applications ranging from consumer home audio to industrial building automation and mobile computers.

The i.MX8M processor has the following characteristics:

 multicore processing: Quad Arm Cortex-A53; Cortex-M4F  GPU: OpenGL/ES 3.1, OpenGL 3.0, Vulkan, OpenCL 1.2  dual independent display interface: MIPI-DSI (4 channels) HDMI 2.0a  video playback: 4Kp60 high dynamic range (H.265, VP9), 4Kp30 (H.264), 1080p60 (MPEG2, MPEG4p2, VC1, VP8, RV9, AVS/AVS+, h.263 and DiVX) and MJPEG-8x8  audio: 6x I2S/SAI (20 + channels, 32 bits per channel @ 384 KHz); SPDIF Tx/Rx DSD512  dual camera interface: MIPI-CSI (each 4 channels)  external memory interface: LPDDR4, DDR4, DDR3L; Quad SPI  with XIP dual USB 3.0 C  with PHY provides dual PCIe in L1 sub-state, fast wake-up function from low power mode  has Gigabit Ethernet controller  operating system: Linux OS, Android, FreeRTOS  temperature: consumer electronics (0 °C to 95 °C Tj) Industrial control (- 40 °C to 105 °C Tj)  package: FCBGA,0.65 mm spacing

Introduction of i.MX 8m Mini Chip

(MYC-C8MMX core board and development board chip)

The i.MX 8m Mini series is based on a high-performance, 2x or 4x Cortex-A53+ Cortex-M4 core processor that runs up to 1.8GHz and supports 16ram 32-bit LPDDR4 / DDR4/ DDR3L. It integrates power management, security unit and rich interconnection interface, with high performance, low power consumption, flexible memory options and high-speed interface, as well as industry-leading audio and video functions. It provides a safe and high-performance solution for the application of the Internet of things.

The structure of i.MX 8m Mini chip is as follows:
