FTDI announced the availability of two serial interface converter cables that incorporate transceivers to facilitate connecting RS-422 or RS-485 based peripherals to a PC’s USB port. Using FTDI’s FT232RQ USB to asynchronous serial interface IC, the USB-RS485-WE converter cable includes an RS-485 transceiver while the USB-RS422-WE cable utilises a RS-42 transceiver. The far end of the 1.8m cables are wire ended (no connector). With the electronics encapsulated in the USB connector, these cables provide a quick, easy and completely transparent method of supporting these serial interface standards. With the complete USB protocol being managed within the FT232RQ device, there is no requirement for designers or end-customers to concern themselves with how to implement the USB standard.

Compact evaluation modules eases integration and development of USB 2.0 High Speed interfaces
 
 

Future Technology Devices International (FTDI) today 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.

FTDI announced the availability of their 5th generation of USB to UART/FIFO ICs. The two new devices support the 480 Mb/s USB 2.0 Hi-Speed specification. The FT2232H and FT4232H devices have the capability of being configured in a variety of industry standard serial or parallel interfaces such as UART or FIFO. The FT4232H offers four configurable interfaces and the FT2232H two configurable interfaces. Two of the FT4232H’s interfaces and both of the FT2232H’s interfaces can be configured as UART, JTAG, SPI, I2C or bitbang mode serial interfaces with independent baud rate generators.

Four Lane PCI Express-to-Local Bus Endpoint Bridge
 
 

The GN4124 is a four lane PCI Express to local bus bridge that is designed to work as a companion for low-cost FPGA devices to provide a complete bridging solution for general applications. In addition to a 4-lane PCI Express compliant PHY interface, the GN4124 also contains the data link and transaction layers, and an applications interface that is ideally suited to FPGA interfacing using a small number of pins.

Key benefits of the GN4124:

  • Supports true bi-directional traffic
  • Easy to use with a pin-efficient attachment interface to low-cost FPGA devices
  • Features an FPGA bitstream loader that enables configurable computing and in-field firmware upgrade
  • Live on power up without FPGA programming
  • Provided with royalty-free FPGA local bus IP
