Introduction

AI Translation

The FT2232D is a USB interface which incorporates the functionallity of two of FTDI’s second generation BM chips into a single device. A single downstream USB port is converted to two IO channels which can each be individually configured as a FT232BM-style UART interface, or a FT245BM-style FIFO interface, without the need to add a USB hub. There are also several new special modes which are either enabled in the external EEPROM, or by using driver commands. These include Synchronous Bit-Bang Mode, a CPU-Style FIFO Interface Mode, a Multi-Protocol Synchronous Serial Engine Interface Mode, MCU Host Bus Emulation Mode, and Fast Opto-Isolated Serial Interface Mode. In addition a new high drive level option means that the device UART / FIFO IO pins will drive out at around three times the normal power level, meaning that the bus can be shared by several devices. Classic BM-style Asynchronous Bit-Bang Mode is also supported, but has been enhanced to give the user
