Introduction

FT4222H is a USB2.0 to Quad-SPI/I²C interface Device Controller with the following advanced features:

• Single chip USB2.0 Hi - speed to SPI/I²C bridge with a variety of configurations
• Entire USB protocol handled on the chip. On - chip OTP memory for USB Vendor ID (VID), Product ID (PID), device serial number, product description string and various other vender specific data.
• Configurable industry standard SPI Master/Slave interface controller. Support configurable data width with single, dual, quad data width transfer mode in SPI master
• SCK can support up to 30MHz in SPI master
• Up to 53.8Mbps data transfer rate in SPI master with quad mode transfer
• Support single bit data transfer with full - duplex transfer in SPI Slave. Support up to 4 channels slave selection control pins in SPI master application
• Configurable I²C Master/Slave interface controller conforming to I²C v2.1 and ×3.0 specification. Support 4 speed modes as defined in the I²C bus Specification, standard mode (SM) up to 100Kbit/s, fast mode (FM) up to 400Kbit/s, Fast mode plus (FM+) up to 1Mbit/s, and High Speed mode (HS) up to 3.4 Mbit/s
• Configurable GPIOs can be easily controlled by software applications via USB bus
• USB Battery Charger Detection.
• Device supplied pre - programmed with unique USB serial number. USB Power Configurations; supports bus - powered, self - powered and bus - powered with power switching.
• +5V USB VBUS detection engine
• Integrated 5V - 3.3V - 1.8V regulators.
• True 3.3V CMOS drive output and TTL input. (operates down to 1V8 with external pull - ups)
• Configurable I/O pin output drive strength; 4 mA(min) and 16 mA(max)
• Integrated power - on - reset circuit.
• USB2.0 Low operating and suspend current; 68mA (active - typ) and 375μA (suspend - typ). UHCI / OHCI / EHCI / XHCI host controller compatible. FTDI’s royalty - free Direct (D2XX) drivers for Windows eliminate the requirement for USB driver development in most cases.
• Extended operating temperature range; - 40°C to 85°C.
• Available in compact Pb - free 32 Pin VQFN packages (RoHS compliant).
