X-chip series - USB while you wait

With an enhanced offer of X-chip series USB chips, it´s possible to immediately choose a type suitable for your application.

This is an archive article published 07/12/2013. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

The family of X-Chip series USB chips we introduced to you in the article „New X-chip series will connect you to USB even easier and faster!“. Gradually these USB chips gain still more popularity thanks to a relatively very simple implementation into a target device. It can be said, that a concept of the X-Chip series is based on a direct conversion USB to a chosen serial interface. i.e. to an interface used in our device (UART, I2C, SPI...), we can choose a suitable chip supporting “our” serial interface. Naturally almost every version is available in various packages. For development and production in smaller quantities it is usually easier to work with packages like SSOP and similar, but for a bigger serial production it´s often more convenient to use a QFN package providing another space saving on a PCB. That´s why we enhance our stable stock offer with the FT230XQ-R chip in the QFN16 package.

For development support, you can find in our store also so called breakout modules providing the simplest way to begin working with X-chips. A novelty in our offer is the UMFT234XF module with the FT234XD chip. FT234XD is almost identical to FT230X, the difference is only in the package with a less pins count.

In case of interest in any FTDI component, please contact us at info@soselectronic.com.




















Advantages / Features of the X-Chip series:

  • USB to serial port interface chips with speeds up to 3.4Mbit/s
  • 13 chip/package options supporting: UART, FIFO, I2C, SPI, and FTDI FT1248 interface
