The QB-V850ESJJ3-TB, or Quest Board V850ESJJ3-TB, is an evaluation board used for embedded MCU, DSP applications. It has a 32-bit processor and features a range of peripheral devices, including serial and timers. As an evaluation board, it is a great platform for developing and testing applications. In this article, we will take a look at the QB-V850ESJJ3-TB\'s application fields and working principle.

QB-V850ESJJ3-TB is a highly integrated evaluation board that supports many of the features of the V850ES processor. It is designed to interface with the V850ES processor via a 32-bit bus that supports two master devices, including the processor itself. It contains a variety of peripherals, which include Serial, Timers, and I/O interfaces. For the purposes of this article, we will focus on the peripheral devices included in the QB-V850ESJJ3-TB.

The first peripheral included in the QB-V850ESJJ3-TB is its Serial port. This is a universal asynchronous receiver/transmitter (UART), which can be used for serial communication between connected devices. It supports up to 8 data bits, one stop bit, and has a baud rate of up to 115,200 bps. The UART also has address and control lines for accessing the port and configuring it.

The QB-V850ESJJ3-TB also includes Timers. These are counter/timer devices that can be used for measuring elapsed time and for generating interrupts. The timers on the QB-V850ESJJ3-TB are 16-bit devices, with a maximum count of 65535. There are four timers, each of which can be independently configured. They can also be used for counting pulses and generating interrupts.

The board also has I/O interfaces that can be used for connecting to external devices. These include a parallel port, a keyboard port, and a video port. The parallel port can be used for connecting peripheral devices. It supports data transfer rates of up to 12 Mbps, and four address lines allow for up to 256 devices to be connected. The keyboard port supports standard PS/2 keyboards, and the video port supports video signals up to 1280x1024 resolution.

The QB-V850ESJJ3-TB evaluation board also includes two on-chip debuggers, which can be used for debugging the board\'s applications. The debuggers can be used to upload the board\'s applications, run them, and troubleshoot them. This is a great tool for those developing applications for the board.

The QB-V850ESJJ3-TB evaluation board is designed for use in embedded MCU and DSP applications, and as such it is an excellent choice for these applications. It is a highly integrated board, with a wealth of features and peripherals. It includes a UART, timers, I/O interfaces, on-chip debuggers, and much more. It is a great platform for developing and testing applications, and is a great choice for embedded MCU and DSP applications.
