Version 1.1

Product Overview

The Cortex®-A8 series EPC/PPC-A8-097-C (PN: CS10768T097) is a high-quality industrial PC. It features a 9.7” resistive touch screen with a resolution of 1024 x 768 pixels and brightness of 350 cd/m2.

It is available both as an embedded solution and as a device hosed in an aluminum casing with bezels, thus facilitating different installation options:

  • Installation on an industrial cabinet

  • Integration with the existing equipment

The EPC/PPC-A8-097-C Industrial PC is based around the powerful CS-SOM335X-V3 System on Module (SoM), powered by the AM3354 Arm® Cortex®-A8 microprocessor unit (MPU). The AM33554 MPU is enhanced with image, graphics processing, peripherals and industrial interface options such as EtherCAT and PROFIBUS. The devices support high-level operating systems (HLOS).

The microprocessor unit (MPU) subsystem is based on the ARM Cortex-A8 processor and the PowerVR SGX™ Graphics Accelerator subsystem provides 3D graphics acceleration to support display and gaming effects.

The AM33554 MPU does not generate extensive heat, so even the thin aluminum housing on PPC version delivers sufficient thermal dissipation.

Power Input

The EPC/PPC-A8-097-C Industrial PC can be powered by a wide range of input voltages: From 6V to 42V DC. The power input connector is a 3-pin, 3.81mm terminal. The polarity and the pinout is clearly marked on the housing of the PPC version, as well as on the PCB itself of the EPC version, as shown in the figure below.


Figure 736: Power Input (embedded/enclosed version)

Note that the “+” sign represents the positive power input, and it is printed both at the casing and as a silk-screen on a PCB of the embedded version. The “-” terminal is shorted to the ground.

Touch Screen

The EPC/PPC-A8-097-C Industrial PC uses a 5-point capacitive touch screen screen. The figure below shows the capacitive or resistive screen connected to the motherboard via the FPC connector.


Figure 737: Capacitive or Resistive Touch Connector


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 float erratically across the display. There are several solutions to this problem:

  1. Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.

  2. Make sure that the EPC/PPC-A8-097-C Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.

  3. Bad GND problem can also be confirmed 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.


There are many connectivity options available on the EPC/PPC-A8-097-C industrial PC. It has 3 x USB 2.0 Host, 1 x USB OTG (can be customized to 2 x Host), 1 x Channel 100M LAN (RJ45) Ethernet connector supporting up to 1 Gbps, and 5 x UART terminals (RS232/RS485).


The serial communication interfaces (RS485, RS232, and CAN) are routed to a 12-pin 3.81mm terminal, as illustrated on the figure below.

USB Connectors

There are 4 x Type A USB HOST connectors onboard, as shown on the figure below.


Figure 739: USB HOST Connectors (embedded/enclosed PC version)


The USB Connectors are defined as HOST by default. If customer needs it work as OTG (slave), please solder a 0Ω 0603 Package Resistor to R140 and R138.


Be careful not to touch surrounding electronic components accidentally while plugging in USB devices into the embedded Industrial PC version.

LAN Connectors

LAN (RJ45) connector provides Ethernet connectivity over standardized Ethernet cables as shown the figure below. The integrated Ethernet interface supports up to 1 Gbps data throughput.


Figure 740: RJ45 LAN Connectors (embedded/enclosed PC version)


Use CAT5 or better cables to achieve full data throughput over maximum distance defined by the 1000BASE-T standard (100m).

WiFi & BT Module

The EPC/PPC-A8-097-C Industrial PC is equipped with the popular Realtek RTL8723 WiFi/BT module that supports BT/BLE 4.0 (with backward compatibility), as well as 802.11bgn 2.4 GHz Wireless LAN (WLAN).


Figure 741: RTL8273 WiFi/BT Module

The enclosed (PPC) variant of the product also includes an SMA connector for an external WiFi/BT antenna, as illustrated in the figure below.

  1. The product does not come shipped with the WiFi/BT module by default.

  2. If the operator mounts the WiFi/BT module on the EPC/PPC-A8-097-C industrial PC, the module uses the USB1 channel to communicate with CPU, so it will occupy the USB1 channel.

3G/4G/LTE Module

The EPC/PPC-A8-097-C Industrial PC is equipped with a mini-PCIe connector that can connect to a 3G/4G/LTE module. The customer will also need a SIM Card Holder and a 3G/4G/LTE Antenna Connector to ensure 3G/4G/LTE works on the EPC/PPC-A8-097-C.

  • The GPIO has been Opt-Isolated and it uses the 24V Logic by default. The GPIO is driven by the on board VDD, you do not need an external isolated power input.

  • The 4 output channels can drive at most 500mA current on each channel.

  • The operator can use the power input that connects to Power Input Connector, if the operator doesn’t want to use an isolated power input.

  • Also, you can use the 5V voltage on-board as power input. The operator must solder a 0Ω resistor on R292 & R293 then you can connect the 5V voltage onboard to the Isolated Power Input Pin.

TF Card Slot

The EPC/PPC-A8-097-C Industrial PC features 1 x TF Card (micro SD) slot. It can address up to 32GB of memory.

The product does not come shipped with the TF Card by default.

Audio Connectors

The EPC/PPC-A8-097-C Industrial PC features some audio peripherals, as well. It has 1 x 3.5mm audio input jack and 1 x 3.5mm audio output jack.

On the embedded panel PC version, the pink connector is the audio input jack (line-in) and the blue connector is the audio output jack (line-out, typically around -10 dBV). On the enclosed panel PC version, both audio input and audio output are clearly marked on the figure below.
