Figure 1-3 Bottom side connectors of development kit

WB10-AT i.MX8M SOM is a high-performance System on Module (SOM) which is

designed based on NXP® i.MX 8M Quad processor. The i.MX 8M Quad integrates four

ARM® Cotex-A53 up to 1.5GHz and one Cotex-M4 cores to provide industry-leading

audio voice and video processing for applications that scale from consumer home audio

to home & building automation, voice assistance & machine vision, healthcare industry,

etc. It supports video quality with full 4K Ultra HD resolution and supports the highest

levels of pro audio fidelity with more than 20 audio channels each @384KHz as well.

WB10-AT SOM module offers a wide range of interfaces - GPIOs, PWM, I2C, SPI, CSI, DSI,

HDMI, UART, USB 3.0 and synchronous audio interface (SAI) that supports full duplex

serial interfaces with frame synchronization, such as I2S, AC97, TDM, and codec/DSP

interfaces. Moreover, this module features an Ethernet PHY on the module to support

Gigabits Ethernet Transceiver with HP Auto-MDIX.

It targets a wide range of embedded products such as medical devices, industrial

automation, Human Machine Interfaces (HMI), data acquisition, and much more.

2.1 CPU

The i.MX8M family of applications processors based on ARM® Cortex®-A53 and Cortex-

M4 Cores provide industry-leading audio, voice and video processing for applications.

The features of the i.MX8M family of processors include the following:

•4xARM Cortex-A53 plus ARM Cortex-M4

•L1 Instruction Cache

32 KB L1 Instruction Cache for A53

www.innocomm.com

16 KB L1 instruction Cache for M4

•L1 Data Cache (each core)

32 KB L1 Data Cache (A7)

16 KB L1 Data Cache (M4)

•The ARM Cortex-A53 Core complex shares

General interrupt controller (GIC)

Global timer

Snoop control unit (SCU)

Unified instruction and data (1MB)

2.2 Memory

WB10-AT i.MX8M SOM is available with up to 3GB of LPDDR4 memory. The default

configuration is 1GB LPDDR4.

2.3 Power Management IC

WB10-AT i.MX8M SOM features Rohm BD7183MWV power management IC.

BD7183MWV is a programmable power management IC that integrates 8 buck

regulators and 7 LDOs to provide all power rails required by SoC and peripherals.

For system management, it provides the following features,

Support software shutdown or hardware power off

External wakeup source

Output monitor

PWROK signal for reset or power off

OVP, UVLO, TSD

2.4 eMMC Storage

The onboard eMMC device is connected on the SD1 pins of the i.MX8M processor in an 8-

bit width configuration.
