FTDI Chip FT4222H USB 2.0 to Quad SPI / I2C Bridge IC
FTDI Chip FT4222H USB 2.0 to Quad SPI / I2C Bridge IC provides a highly advanced, feature-rich single-chip bridging solution with support for multiple data lines and a wide variety of configurations to maximize design flexibility. The FT4222H's SPI configurable interface allows the device to serve as an SPI Master/Slave interface controller and support all 4 SPI modes. The device delivers single, dual, and quad data width transfer with total data rates of up to 27Mbit/s. The integrated configurable I2C Master/Slave interface controller conforms completely with both I2C v2.1 and v3.0 specifications.The FT4222H supports 100kbit/s standard mode (SM), 400kbit/s fast mode (FM), 1Mbit/s fast mode plus (FM+) and 3.4Mbit/s high speed mode (HS). Additionally, the FT4222H supports server 2008 R2, 2012 R2, Windows 7, 8, 8.1, and 10 (32 and 64-bit) drivers. The device also allows designers to control configurable general-purpose IOs (GPIOs) using software applications via the USB bus. In addition, the FT4222H includes 128 Bytes one-time-programmable (OTP) memory space for storing vendor-specific information.
The FTDI Chip FT4222H USB 2.0 to Quad SPI / I2C Bridge IC is available in a compact, Pb-free VQF-32 package.
