Hello, Welcome to Dasenic

The FT2232H is a USB 2.0 Hi-Speed (480 Mbps) interface IC that provides a bridge between USB and peripheral devices such as UART, I2C, SPI, and JTAG. This chip contains two independent serial interfaces and is widely used in applications requiring USB communication. Functions - USB Interface: Provides a high-speed USB 2.0 interface. - Dual Mode Operation: Can operate in two independent serial modes - MPSSE (Multi-Protocol Synchronous Serial Engine) mode for synchronous serial communications and asynchronous serial port (UART) mode. - Flexible Interface Options: Supports various protocols including UART, I2C, SPI, JTAG, and GPIO. - Integrated EEPROM: Allows configuration of device parameters. - Multiple Chip Selects: Supports multiple devices on the same bus and can drive different peripheral devices. Applications - Embedded Systems: Used in designs that require USB connectivity for microcontrollers and processors. - Industrial Automation: Facilitates communication between PCs and industrial devices. - Development and Prototyping: Commonly used in development boards for program debugging and interface testing. - Data Acquisition Systems: Interfaces with sensors and other hardware components. - USB-to-Serial Converters: Used in devices requiring conversion between USB and TTL/serial communications. Alternative Parts - FT232H: A similar USB to UART/I2C/SPI interface chip, but with single channel operation. - FT2232D: An older version that lacks some of the high-speed features of the FT2232H. - CP2102: A USB to UART bridge that may serve similar purposes in simpler designs. - CH340: A cost-effective USB to serial converter that can be used in place of FTDI products for some applications. Embedded Modules - FTDI USB Development Modules: These modules incorporate the FT2232H chip for rapid development and prototyping. - USB-Serial Adapter Modules: Many commercial USB-serial adapters utilize FTDI chips for reliable performance and compatibility. - Mikroelektronika Chips: Some Mikroelektronika development boards include FT2232H for enhanced USB connectivity.
