An Evaluation and Demonstration Boards and Kits is a device designed to facilitate easier and faster development and evaluation of devices or modules used in embedded electronic and mechanical systems. AC320032-2 is a powerful and complex board belonging to this category, specially intended for application in industrial, automotive and medical industries. This board offers a wide range of applications, all of which relate to controlling a variety of devices, from medical electronic systems to automotive cabin systems.

A simplified version of the general schematic of the AC320032-2 board is shown in figure 1. The board includes two host controller areas, connected to several peripheral controllers. The first area, A, is based on an ARM Cortex-M3 processor, and contains a 32-bit user flash memory, three 66-pin expansion connectors, and a 16-bit analog-to-digital converter (ADC). Additionally, for enhanced communication and instrumentation, this board contains four Industrial Serial peripheral interfaces, two CAN2.0B, two UART, two I2C, one 1-Wire, one I2S and one SPI. All periphery controllers are coupled with each other by a low-speed subsystem consisting of multi-stage power supply, system clock and reset logic. The second area, B, is based on a PIC32MX core and includes a 10/100 Ethernet controller, an analog-to-digital converter (ADC), and a 400 MHz System on Chip (SoC) with full-duplex Ethernet, I2S, SPI, 1-Wire and CAN2.0B support.

The AC320032-2 board is mainly intended for two applications. Firstly, for providing a comprehensive solution for general embedded systems needs, developed for the industrial, automotive and medical industries. This includes developing low-cost solutions for devices such as motor controllers, valve controllers, and communication systems. Secondly, the board is also used in hobbyist projects and standalone products where the advanced features mentioned above can be used to increase system performance and add flexibility.

The working principle of the AC320032-2 board is based on the ARM Cortex-M3 processor as the core of the board. This processor is responsible for processing data received from peripheral controllers or from external devices, such as remote controllers. Depending on the received inputs, the processor is then responsible for sending the appropriate output signals to the peripheral controllers to operate different devices. Additionally, the Cortex-M3 processor can be used to execute user-specific code, for example to implement any specialized function required by the user. Finally, the system clock, reset logic and multi-stage power supply are all responsible for controlling the execution of the processor’s code and ensuring the system works as expected.

In conclusion, the AC320032-2 board is a powerful and complex Evaluation and Demonstration Boards and Kits, especially suitable for application in the industrial, automotive and medical industries. This board offers a wide range of applications, all of which are related to control and instrumentation, and can be used to develop low-cost solutions for a variety of devices. The board works mainly based on the ARM Cortex-M3 processor, responsible for controlling the peripheral controllers, executing user-specific code, and ensuring all the different parts of the board work as expected.
