1 Introduction 1.1 Product Overview FSS MB9BF506R EV-Board (PN: FSSDC-9B506-EVB) provides an economical and simple means for study usage for MB9B506 series MCU. The board compatible with both 3.3 and 5V system contains abundant external resources (LCD, buttons, UART, Nand Flash, CAN…) to demonstrate MCU periphery function. It also provides standard 20 pin JTAG interface, which is both compatible with IAR and Keil debug tool. In addition, it allows On-board programming with both USB
