Evaluation and Demonstration Boards and Kits could help users easily evaluate and demonstrate electronic designs, CDKWM8956-S-1 is a board in this type products, and its application field and working principle are discussed as following.

CDKWM8956-S-1 is an evaluation and demonstration board based on Single-Chip MCU, 8-bit W7600P MCU from WIZnet. It is composed of WIZnet board, S-1 board, W7600P MCU board and the jumper wires and pin parts. This board is not only applicable to W7600P MCU, but also applicable to any standard UART debug adapter, so users are free to test and evaluate the performance of W7600P MCU, ARM Cortex-M4 MCU, or any MCU with UART debug adapter.

The primary communication interface between CDKWM8956-S-1 and W7600P MCU is UART, and it is also equipped with I2C, SPI and GPIO asynchronous interface. The signal level is 5V. Moreover, CDKWM8956-S-1 provides the DC power supply, which supports the current up to 3A. The CDKWM8956-S-1 works as an independent power source for the debugging hardware and the upper MCU. Besides, users can swich between the on-board power supply and the external power supply just by welds a jumper.

CDKWM8956-S-1 has various applications, such as ZigBee communication and control system, IoT system, the home and commercial environment monitoring or control system and so on. It can be used to develop and debug WIZnet products, such as W7600P MCU, W5500 Ethernet module and W7500P MCU. Generally, the key point of CDKWM8956-S-1 is that it supports the development of applications that require long time operations.

The working principle of CDKWM8956-S-1 is based on the combination of main board and daughter board. The main board of WIZnet is a motherboard with independent power supply, debug adapter, display, etc., and the daughter board can be connected to any MCU equipment by plugging in the pins. The WIZnet debugging adapter is the bridge between the development platform and the MCU. The CPU executes a series of instructions and conveys the instructions to the CPU core through the debugger. The debugging adapter is compatible with the Ac6 STM32 debug adapter, which can be configured as a UART, I2C and other serial bus communication, and can be programmed through the debugger. In the debugging mode, all of the eight channels of UART can be used. In other multi-channel communication mode, users can choose to activate or deactivate different channels of UART as they want.

In short, CDKWM8956-S-1 is an evaluation and demonstration boards and kits that suitable for various applications, and its working principle is based on the combination of main board and daughter board. The main board provides power, debugger, display, etc., and the daughter board can connect to any MCU equipment. In addition, it supports the development of applications that require long time operations and users can configure the channels of UART as they needed.
