New X-chip series will connect you to USB even easier and faster!


X-chip USB series from FTDI brings even higher functionality on a chip, including battery charging detection. Speeds-up development, saves space and decreases power consumption.

USB solutions specialist Future Technology Devices International Limited - FTDI has supplemented its portfolio of USB to serial interface products with new X-Chip series. X-Chip series consisting of 13 chips (7 types in various package options) complements the existing FT-R and FT-H series. New series supports a broad selection of interface types, such as basic UART, full UART, FIFO and I2C, as well as FTDI’s proprietary FT1248 I/O (including enhanced SPI).

Advantages / Features:

  1. USB to serial port interface chips with speeds up to 3.4Mbit/s
  2. 13 chip/package options supporting: UART, FIFO, I2C, SPI, and FTDI FT1248 interface
  3. speed-up of development and minimum external components required
  4. battery charging detection (BCD, DCP) function
  5. internal clock generation, extended clocking features
  6. Low power – typically 8mA active / 125uA suspend
  7. low pin count and small footprints
  8. Configurable CBUS pins for BCD, driving LED, clock-out, or GPIO
  9. Internal 2KB MTP memory, programmable via USB and I2C
  10. Internal 3.3V level converter
  11. Supports Bus-Powered (5V) or Self-Powered (3.3V) applications
  12. -40 °C to +85 °C extended operational temperature range

Through X-Chip, engineers are provided with a feature-rich USB 2.0 interface solution with a smaller size and a lower pin count. High level of integration, including integrated crystal and MTP (Multi-time programmable) memory for configuring and storing the device descriptors and an internal clock source, solves major board level concerns, such as better space utilization and reduced power consumption. Devices in the series are capable of data rates of up to 3.4 Mbits/s, while maintaining low power consumption, <8mA (typical) when fully active and <125 μA (typical) while in suspend mode

With recent amendments being made to the USB specification regarding more rapid charging of portable electronics devices, the X-Chip has built-in functionality to detect a charging port (battery charging detection – BCD, dedicated charging port – DCP) and cause a logic to switch from data transfer to charging mode. This feature means that detection does not have to be carried out by the system’s microcontroller, thereby allowing it to focus fully on its core activities. The end result is a simpler detection process and the capability to charge at a higher current level which shortens the time required for battery charging.

 The devices in the X-Chip series are offered in compact SSOP, QFN and DFN packages. Each has an operational temperature range of -40 °C to +85 °C. X-chip series has an internal 3.3V converter and supports 1.8 to 3.3V I/O voltages. As all the necessary USB support and bridging intelligence has been integrated into these devices and pre-validated, the expense, time and engineering resource needed to bring Full Speed USB connectivity into system designs is markedly reduced. FTDI provides support and royalty-free downloads for a wide selection of OS: Windows, Android, Mac OS, and Linux.

Overview of all new types will provide you the attached table, X-chip brochure and X-chips overview. Available are 7 basic types - FT200XD, FT201X, FT220X, FT221X, FT230X, FT231X and FT240X. FT200XD is the smallest one, in a tiny 10-pin DFN package. All other types are available in SSOP and QFN packages. Detailed description will provide you FT200XD, FT201X, FT220X, FT221X, FT230X, FT231X and FT240X datasheets. An example of an easy to use I2C/USB slave converter illustrates the picture below. Further details about battery charging you can find in the AN_175 application note.

Together with these chips, FTDI has released a wide-selection of development modules. Also available are so-called breakout modules, providing the simplest method to connect to a USB host. You can choose from 4 types of breakout modules – UMFT200XD, UMFT201XB, UMFT220XB a UMFT230XB. Evaluation modules are larger than breakout modules, but provide access to all pins.
