Figure 2. i.MX 8M Nano UL DDR3L EVK board overview
Type-C Port2 is the only power supply port, and it must be always supplied for system running.
i.MX 8M Nano EVK is not a typical use case of the PD device. It is supplied by the PD charger only, but with a power
switch. When the switch keeps OFF for more than 5.5 seconds after adapting the PD charger, the charger (Source)
will repower EVK (Sink) after the system initiates the PD software. See Section 6.5.7 in the
Universal Serial Bus
Power Delivery Specification Revision 2.0. There are two ways to avoid repower:
• The power switch must always be in the ON position before attaching the PD charger.
• Change the software to disable the PD function, and make it Type-C supply only.
NOTE
2.1 Processor
The i.MX 8M Nano UltraLite applications processors represent NXP Semiconductor’s latest achievement in high performing,
scalable, and cost optimized solutions. These applications processors can enable the growing market of smart, secure, connected
devices. The i.MX 8M Nano UL applications processors feature NXP’s advanced implementation of the Quad Arm
®
Cortex
®
-A53+
Arm Cortex-M7 cores, which operate at speeds up to 1.4 GHz and 750 MHz respectively. Each i.MX 8M Nano UL device provides
a 16-bit LPDDR4/DDR4/DDR3L memory interface and other interfaces for connecting peripherals, such as MIPI Camera, WLAN,
Bluetooth
™
, Ethernet, Digital Mic, and multi-sensors.
