FT2232H-56Q-TRAY

FT2232H-56Q-TRAY is FTDI’s dual-channel USB 2.0 Hi-Speed (480 Mbps) interface IC. It provides two independent channels that can operate as UARTs or be configured with the MPSSE (multi-protocol synchronous serial engine) for SPI, I2C, or JTAG, or used as FIFO/buffer interfaces. It acts as a USB-to-serial bridge, requiring FTDI drivers, and supports flexible I/O voltages via VCCIO for compatibility with 3.3V/5V logic. The “56Q” denotes the 56‑pin QFN package, while “TRAY” indicates shipping in tray form for OEM production. Typical uses include USB-to-UART adapters, USB-to-SPI/I2C bridges, in-circuit debugging, and test equipment. For exact electrical specs, pinout, timing, and programming details, consult the FT2232H datasheet and hardware user guide.

Direct drop-in equivalents to FT2232H-56Q-TRAY do not exist; it’s a dual-channel USB-to-serial/FIFO with MPSSE in a 56‑pin QFN. Closest options:
- FTDI: FT4232H (quad-channel, similar MPSSE capabilities), or other FT2232H packaging variants (same family).
- Non-FTDI: Silicon Labs CP210x (single UART), CH341x (multi-function USB-UART; not a direct dual-channel match).
Choose by required channel count and protocol support (UART, SPI/I2C/JTAG).

Here are the main features of FT2232H-56Q-TRAY:
- USB 2.0 Hi-Speed device (480 Mbps) with dual independent channels (A and B).
- Each channel can be configured as UART or FIFO; both can use the MPSSE engine for
SPI, I2C, JTAG, and other protocols.
- Flexible I/O: CBUS configurable pins and general-purpose I/O for handshaking, LEDs, etc.
- Supports independent baud rates on each UART channel; high data throughput.
- Integrated USB transceiver and clocking; no external MCU required.
- 56-pin QFN (56Q) package, supplied in tray packaging.
- Wide driver support (Windows, Linux, macOS) via FTDI drivers.
- Ideal for USB-to-serial adapters, SPI/I2C/JTAG adapters, and multi-protocol embedded interfaces.

- Pin count: 56 pins (QFN-56 package; FT2232H-56Q refers to the 56-pin version).
- Function: Dual-channel USB-to-serial/multi-protocol interface. Channels A and B can operate as UART/FIFO or use the MPSSE to implement I2C, SPI, JTAG, etc., via USB 2.0.

- Manufacturer: FTDI (Future Technology Devices International Limited).
- What kind of company: A semiconductor company that designs and manufactures USB connectivity ICs and USB interface solutions (e.g., USB-to-serial/UART bridge controllers). Based in Edinburgh, Scotland, UK.

Applications of FT2232H-56Q-TRAY:
- USB-to-dual UART bridges for microcontrollers/SoCs
- USB-to-SPI and USB-to-I2C master/slave interfaces
- JTAG and other debug interfaces via the MPSSE engine
- In-system programming and flashing of SPI flash or memory devices
- FPGA/ASIC development and probe/debug tools
- Custom parallel/bit-bang data I/O and data-acquisition interfaces
- USB-based programmers, logic/protocol analyzers, and test equipment
- Prototyping and lab instrumentation for embedded systems
Note: -TRAY denotes packaging; core capabilities come from FT2232H’s dual channels and MPSSE.

It uses a 56-pin QFN package (QFN56); the -TRAY suffix just indicates tray packaging.
