Future Technology Devices International (FTDI) has launched two evaluation modules to support its recently announced FT2232H and FT4232H USB 2.0 High Speed devices.
 These 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 36 x 30 x 12mm. Each module is said to provide access to all the required signals through two 26 way (2 rows, 0.1" pitch) male headers measuring 32.9 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 way 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 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.
Each module is implemented with an FTDI USB 2.0 High Speed device which includes a +1.8 V LDO regulator, an integrated power on reset 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.
