PPC-A9-121-U-C Product Overview
Chipsee IPC Page 4 of 19

Automotive applications
ATM…
The PPC-A9-121-U-C Industrial Panel PC is based around the powerful CS-SOM-iMX6Q
System on Module (SoM), powered by the i.MX6Q Arm Cortex -A9 quad-core Application
Processor (APU). The i.MX6Q APU represents the latest achievement in integrated
multimedia applications processors, delivering high-performance computing, an abundance
of integrated peripherals, and high power eciency.
This product also features a broad range of connectivity options, providing a high level of
scalability for various use cases. It is the perfect solution for power-constrained applications
on the Edge, acting as a robust control unit for collecting, processing, and aggregating eld
data. The i.MX6Q APU is part of NXP’s EdgeVerse™ edge computing platform.
The NXP i.MX6UL APU does not generate extensive heat, so even the thin aluminum
housing on PPC version delivers sucient thermal dissipation. With its junction temperature
from -40 to +125°C, the APU itself is well suited for extended temperature range in both
automotive and factory environments.

Attention
A capacitive touch screen is susceptible to power noise and Electromagnetic Radiation (EMR). It may cause LCD ripples
or even capacitive touch malfunction. If using a capacitive multi-touch test application, you might notice the touch
points oat erratically across the display. There are several solutions to this problem:
Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.
Make sure that the PPC-A9-121-U-C Power Input connector (pin 3) is properly connected to the Power System
Ground to provide sucient EMI shielding and eliminate the problem entirely.
Bad GND problem can also be conrmed by touching pin 3 of the Power Input connector with one hand while
operating the capacitive touch screen with the other hand. In this case, the operator’s body acts as the Power
System Ground.
