PPC/EPC-A8-070H-C

Version 1.0

Product Overview

The Cortex®-A8 series PPC/EPC-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 PPC/EPC-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 PPC/EPC-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.

Touch Screen

The PPC/EPC-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.

../../../../../_images/TS_CON.jpeg

Figure 584: 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:

  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 PPC/EPC-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.

  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.

Connectivity

There are many connectivity options available on the PPC/EPC-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, RS482, and CAN) are routed to a 12-pin 3.81mm terminal, as illustrated on the figure below.
