Overview

The SIF-TMD card can provide serail communication function (USB to UART) to the motherboard, users can connect this daughter card to FPGA motherboard which equipped Terasic TMD connector or GPIO connector (use jump wire) to get the UART protocal feature.User only need to connect the Host to the SIF-TMD card through the USB cable to establish the serail data transmision between the FPGA and the Host. In addition, the SIF-TMD also provides I2C interface EEPROM and SPI interface FLASH, allowing users to use FPGA to access these memories to realize the features of data access.

Components

This chapter will introduce the hardware components of the SIF-TMD card.

USB to UART Inteface

The UART serial interface is designed to perform communication between the board and the PC, allowing a transmission speed of up to 2Mbps. This interface on the SIF-TMD card wouldn’t support HW flow control signals. The physical interface is done using UART-USB on-board bridge from a CH340E chip and connects to the host using a Mini-USB connector. For detailed information and host driver for the CH340 chip, please refer to the datasheet, which is available on the manufacturer’s website.
