Hardware Design Overview

The detachable DUT board can be separated from the provided MCU board for connection to a user-supplied alternate microprocessor or FPGA board. The inter-board headers are located on 0.1” (2.54 mm) grid for compatibility with generic prototyping boards. All host interface signals go through the inter-board headers. Numerous configuration pins are controlled by DIP switches on the upper DUT board; these signals are not available on the inter-board headers.


The lower ARM Cortex M3 board is based on the flash-programmable Atmel AT91SAM3U-EK microprocessor. A 4-signal Serial Peripheral Interface (SPI) connects to the HI-3210 DUT. A UART-based serial port provides RS-232 console I/O (optional). An uncommitted USB 2.0 port is available for future expansion. Two pushbuttons are available for software interaction. A RESET pushbutton resets the ARM microprocessor, which in turn controls the DUT Master Reset signal.


The ARM Cortex M3 board includes “J-Link On Board” debug interface, licensed from, providing out-of-box readiness without having to buy a costly JTAG debug cable. The kit includes a simple USB cable for connecting the board’s debug interface to your computer. (For users already owning an ARM debug interface with ribbon-cable connector, an ARM-standard 2x10 debug connector provides debug connectivity. In this case, jumper JP2 on the bottom of the lower board should be soldered closed to disable “J-Link On Board”).
