ARMv8 Processor
The 64-bit NXP™ i.MX8M Mini Quad Core ARM® Cortex™-A53 SoC processor
includes many peripherals for supporting secure network and multimedia processing
and connectivity in small embedded applications.
● Quad Cortex-A53 processing cores
● Core operating frequency of 1.6GHz
● DDR4 SDRAM supports up to 2133MTps data rate
● Interfaces include Gigabit Ethernet, PCIe Gen2, and USB 2.0
● Peripheral interfaces include eMMC, SPI, I2C, UART, and GPIO
● Integrated acceleration for security
● Integrated 2D & 3D GPU (1x shader, OpenGL®ES 2.0)
● MIPI Display DSI & Camera CSI
● 1080p60 Encoder and Decoder
● IEEE1588 precision stamp protocol support
DDR4 SDRAM
The SDRAM resides in one LPDDR4 device soldered directly to the board. This
architecture supports DDR4 memory capacities from 1GByte to 4GBytes. The 32-bit
DDR4 interface operates at up to 1500MHz for supporting fast data transfer rates. The
factory default includes 1GByte of LPDDR4.
System Flash
The System Flash supports eMMC memory capacities from 4GBytes to 64GBytes. The
8-bit data bus interface supports double data transfer rates. The default boot device is
the eMMC Flash. The factory default is 8GBytes.
Mini-PCIe Sockets
Mini-PCIe is a small form factor PCI card that uses the same signal protocol, electrical
specifications, and configuration definitions as conventional PCI Express. The board
includes Gen 2 capable Mini-PCIe sockets with the following enhancements to the PCI
Express standard.
● The 3.3V power for the socket is increased from a maximum of 3.3W to 8W for
accommodating higher power radios. The 8W limit is due to the 0.5A limit of the
individual socket pins.
● The PCIe reset for the socket is unique and under software control.
● Certain sockets support both PCIe and USB 2.0 signaling
USB Support
● Slot J6 Supports PCIe, USB 2.0, SIM

PCIe Socket Reset & WiFi Disable
The Mini-PCIe sockets support individual software programmable resets and shared
WiFi disable signals. The reset signal is controlled through the processor PCIe
interface and the WiFi disable signal is controlled through the Gateworks System
Controller.
Nano SIM Expansion
A Nano SIM socket extends the functionality of the SBC.
The Nano SIM (4FF) socket accepts 12.3 mm by 8.8 mm cellular SIM cards. The SIM
signals are routed to a single Mini-PCIe socket for cellular modem usage.
GbE Ethernet
The SBC supports Gigabit Ethernet. The Ethernet ports operate in a 10BASE-T,
100BASE-TX or 1000BASE-T configuration and include auto MDI/MDIX for
automatically switching data receive and data transmit pairs. Additional features include
full-duplex operation as well as support for auto- negotiation. The data interfaces
include direct-touch ESD protection that exceeds IEC61000-4-2-ESD. The Ethernet
MAC addresses are programmed into the Gateworks System Controller Configuration
EEPROM during automated factory testing.
The IEEE802.3 compliant Ethernet MAC Media Access Controllers are located in the
processor. The Gigabit Ethernet Port MAC communicates to an external PHY physical
layer device through an RGMII interface. The external PHY is reset under software
control using a processor digital I/O signal.
The RJ45 connector for the Gigabit Ethernet Port includes integrated status lights. The
green light is on for link and blinking for activity. The yellow status light indicates speed.
The yellow light is off for both 10Mbps and 100Mbps, and on for 1000Mbps.
The SBC input power can be provided through the Gigabit Ethernet Port jack in a
Passive Power over Ethernet architecture. This is discussed in greater detail at the end
of this section. The RJ45 connectors can be replaced with a header as an ordering
option.
USB Ports
The processor includes two USB ports. The default processor supports USB 2.0. Future
SOMs may support USB 3.0. One port is connected to a USB Type-C connector and the
other to a Mini-PCIe socket. The USB ports support low-speed 1.5Mbps transfers,
full-speed 12Mbps transfers, and high- speed 480Mbps transfers. The SBC is
configured as a Downstream Facing Port capable of sourcing 5V at 1.5A. The output
power is enabled through a CPU GPIO signal (GPIO[1]:DIO[12]) and the current fault
monitoring is monitored through another CPU GPIO signal (GPIO[1]:DIO[13]).
