EPC/PPC-A8-070H-C¶
Version 1.1
Product Overview¶
The Cortex®-A8 series EPC/PPC-A8-070H-C (PN: CS10600T070) is a high-quality industrial PC. It features a 7.0” five-point capacitive and four-wire resistive touch screen with a resolution of 1024 x 600 pixels and brightness of 500 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-A8-070H-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-A8-070H-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 711: 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-A8-070H-C Industrial PC uses a 5-point capacitive and resistive touch screen. The figure below shows the capacitive or resistive screen connected to the motherboard via the FPC connector.
Figure 712: Capacitive or Resistive Touch Connector¶
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 float 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 EPC/PPC-A8-070H-C Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.
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.
Connectivity¶
There are many connectivity options available on the EPC/PPC-A8-070H-C industrial PC. It has 2 x USB 2.0 Host (can be customized to Host or OTG), 1 x Channel 100M LAN (RJ45) Ethernet connector supporting up to 1 Gbps, and 5 x UART terminals (RS232/RS485).
RS232/RS485/CAN¶
The serial communication interfaces (RS485, RS232, and CAN) are routed to a 12-pin 3.81mm terminal, as illustrated on the figure below.

Note
The OTG Connector is defined as HOST by default. If customer needs it work as OTG (slave), please solder a 0Ω 0603 Package Resistor to R119 and R121 as shown in the above.
Warning
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 715: RJ45 LAN Connectors (embedded/enclosed PC version)¶
Note
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-A8-070H-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 716: 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.
Figure 717: WiFi+BT Antenna¶
Note
The product does not come shipped with the WiFi/BT module by default.
If the operator mounts the WiFi/BT module on the EPC/PPC-A8-070H-C industrial PC, the module uses the USB1 channel to communicate with CPU, so it will occupy the USB1 channel.
