FTDI X-Chip Series Interface ICs & Modules

FTDI's X-Chip Series Interface ICs & Modules target a wide range of interfaces, including basic and full UART, FIFO, I2C, SPI and FTDI's FT12485, allowing engineers to easily incorporate USB connectivity into their systems. X-Chip Series Interface ICs are USB 2.0 full speed chips which join the USB 2.0 high-speed, H Series of devices and the popular R Series of integrated circuits already in production today. Besides offering an expanded, world class feature set, these FTDI X-Chip Series Interface ICs offer reduced pin counts. Whether the engineer needs a leaded, SSOP package or a leadless QFN package, pin-outs have been minimized and range from a 10 pin DFN package for the FT200XD I2C solution to 24 pins for a FIFO to USB bridge. X-Chip Series Modules help engineers integrate FTDI's X-Chip Series Interface ICs into new and existing designs.
