Evaluation modules ease integration and development of USB 2.0 High Speed interfaces

Future Technology Devices International (FTDI) has announced the availability of two evaluation modules to support their recently announced FT2232H and FT4232H USB 2.0 High Speed devices, which have the capability of being 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). Each module provides access to all the required signals through two 26 way (2 rows, 0.1” pitch) male headers measuring 32.9mm x 5.08mm. The pin length is 6mm.

The FT2232H_mini-module provides two independent configurable interfaces while the FT4232H_mini_module offers four such channels.

Aimed at system developers, the modules provide a convenient method of integrating a USB 2.0 High Speed interface to a number of asynchronous serial interfaces (UART, JTAG, I2C, SPI or customised serial interfaces) or parallel (FIFO) ports. Using a dual (FT2232H) or quad (FT4232H) device, the modules offer the ability to quickly evaluate, model or prototype systems that require USB 2.0 High Speed connectivity, while implementing the complete USB 2.0 protocol with no additional firmware required. There is no need for users to understand any low level USB 2.0 protocols.

Each module is implemented with the a highly integrated FTDI USB 2.0 High Speed device which includes a +1.8 V LDO regulator, an integrated power-on reset (POR) function and an on-chip clock multiplier PLL (12 MHz to 480 MHz). A USB mini-B type connector (socket) on the PCB provides easy USB connectivity.

Drivers for the modules are the same as those used for the FT4232H and FT2232H.
