Myon II

Documentation version 1.2

Introduction

The Myon II is the second module based on the Myon SOM standard.

The Myon II is powered by NXP i.MX 8M Mini processor, which is designed to meet the latest

market requirements of connected streaming audio/video devices, scanning/imaging devices and

various devices demanding high-performance and low-power.

The i.MX 8M Mini family of processors features advanced implementation of a quad ARM®

Cortex®-A53 core, which operates at speeds of up to 1.8GHz (consumer version) and 1.6GHz

(industrial version). A general purpose Cortex®-M4 core processor is for low-power processing. A

32-bit LPDDR4 is used for memory.

There are a number of i.MX 8M Mini interfaces for connecting peripherals, such as displays,

cameras, GPS and sensors, which are extended by module components such as a stereo, hi-fi

quality audio-codec.

Additional peripherals may be added through two 100pin Hirose DF40 connectors. The pinning of

both connectors is to a large extent compatible to Myon I.

The main differences are:

+ an additional USB2.0 port

+ a second SDIO card interface

+ PCIE

+ RGMII Gbit Ethernet interface

+ SPDIF and Stereo Line-In

+ a mounting option for +3V3 or 1.8V IO-voltage.

It misses the following Myon I features:

- Li-Ion Battery charger.

- second 2ch MIPI-Camera port.

- on-board wireless chipset.

Evaluation-Version

Version with LVDS Display interface, size 48,5 x 32,5 x 4.2 mm (size of 2 SD-Cards):

1 Pin-Description

The Myon II got two Hirose DF40C-100DP-0.4V pin-headers J70 and J71.

These can be mated with following receptibles:

DF40C-100DS-0.4V (1.5mm stack height)

DF40C-3.0-100DS-0.4V (3.0mm stack height)

All signals needed for operation are placed on the main connector J70.

Note on Display-Interface:

The module can be configured for Mipi-DSI or LVDS display-output by mounting option.

Note on VDD_IO:

VDD_IO can be configured by mounting options either to +3V3 or +1V8.

Note on VDD_ENET:

VDD_ENET can be controlled by LDO5 of BD71847 PMIC. U-Boot defaults to set this to VDD_IO

voltage level. A mounting option exist to supply this voltage externally through J70-50.

2. Interfaces This chapter includes a short description of all interfaces of the Myon II.

Please consult the processor datasheet for detailed information.

2.1 Power Supply

There are two main power supply scenarios. Battery power supply and external power supply.

The Myon II got two power-inputs which are treated equal (VBUS and VBAT) through an ideal OR

diode. In comparison to the Myon I, the Myon II does not have a battery-charger.

For cost savings a mounting option exist to override the ideal OR diode.

Name Description

VBAT Main power input.

VBUS Auxiliary power input.

VDD_SPEAKER 2.5V .. 5.5V Audio Speaker Supply.

+3V3 +3.3V power output (max. 600mA)

VDD_1V8 +1.8V power output (max. <50mA)

Note that this regulator also supplies on-board

peripherals. So the current available for use by the

baseboard is less than 50mA.

VDD_ENET +1.8V...+3.3V power output (max. 300mA)

VDD_IO +1.8V or +3V3 power output (max. <300mA)

Note that this regulator also supplies on-board

peripherals. So the current available for use by the

baseboard might be less than 300mA. If possible the

IO-voltage of the baseboards peripherals should be

connected to this supply.

2.2 Control-Signals

Name Description

ONOFF Connect to power-on/off button. The signal got a

pull-up to an internal voltage. Only pull signal to

ground by external circuit.

RESET_IN_N Negated reset input. 0: reset device, 1: normal

operation.

RESET_OUT_N Negated reset output. 0: device in reset, 1: normal

operation.

JTAG_MODE Leave unconnected for JTAG Native Mode / normal

operation.

Connect to VDD_IO for JTAG Boundary Scan testing.

USB1_VBUS Connect to VBUS(+5V) of USB-OTG-connector. Used

by software to detect if USB-Slave cable got

connected.

USB2_VBUS Connect to VBUS(+5V) of USB-OTG-connector. Used

by software to detect if USB-Slave cable got

connected.

2.3.1 GPIO

GPIO pins may be configured as input or outputs and with pull-up, pull-down or no pull, hysteresis,

open-drain –behavior. The pins have a programmable drive-strength and slew-rate settings.

Please view the i.MX 8M Mini datasheet on which settings are possible for each individual pin.

2.15 Realtime Clock

If it is needed, it is recommended to use an external Realtime-Clock i.e. EPSON RTC-8564JE to

keep the time during low-power or power-off -modes.

3. Specifications

3.1 Absolute Maximum Ratings

Absolute maximum ratings reflect conditions that the module may be exposed outside of the

operating limits, without experiencing immediate functional failure. Functional operation is only

expected during the conditions indicated under “Recommended Operating Conditions”. Stresses

beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the

module. Exposure to absolute-maximum rated conditions for extended periods may affect device

reliability.

Supply current (typ.) Measured on i-PAN M7.

Power consumption dramatically depends on the usage scenario.

This includes things like if the processors operating point (frequency) can be set to a lower level; if the GPU can be used by an application; the selected display-resolution or if the module supplies external peripherals i.e. a speaker.

We recommend to use a 2A voltage-regulator to supply the module.

temperature The chip temperature of processor or LPDDR4 might get hotter. The max. case temperature of i.MX 8M Mini is specified with +95°C (consumer) and +105°C (industrial).

A higher refresh-rate-setting is needed when case temperature of LPDDR4 is expected to rise above +85°C.

Temperature of eMMC influence the achievable Data Retention.
