There´s only one original, even though with a fake, it´s possible to “gain” also something unwanted - hours of debugging and costs for exchange.
The FTDI FT2232H Mini-Module and FT4232H Mini-Module are miniature USB 2.0 high-speed evaluation modules that support the new FT2232H and FT4232H USB 2.0 high-speed devices that can be configured in a variety of industry standard serial or parallel interfaces such as UART or FIFO. The module PCB measures just 36mm (L) x 30mm (W) x 12mm (H including connector pins). The Multi-Protocol Synchronous Serial Engines (MPSSE) are capable of speeds up to 30Mbits/s and provide flexible interface configurations. The entire USB protocol is on a chip with integrated LDO regulator and PPL. Each FTDI Mini-Module provides access to all required signals through two 26 way (2 rows, 0.1" pitch) male headers measuring 32.9mm x 5.08mm. The pin length is 6mm. These products allow customers to quickly evaluate the FT2232H and FT4232H device and drivers prior to commencing their own design.
FTDI has announced the release of two new ICs - the FT2232H Hi-Speed USB Dual UART/FIFO IC and the FT4232H Hi-Speed USB Quad UART IC.
Both of these new ICs are USB 2.0 Hi-Speed devices operating at 480Mbps. In addition to the standard UART and FIFO modes, each of these devices supports FTDI's bit-bang modes and contains two multi-protocol synchronous serial engines (MPSSEs) to allow communication using JTAG, I2C and SPI protocols. They are the 5th generation of USB devices and have the capability of being configured in a variety of industry standard serial or parallel interfaces.
The FT2232H and FT4232H are available in Pb-free (RoHS compliant) 64-pin LQFP and QFN packages.
