UMFT4222EVUSB2.0 to QuadSPI/I2C Bridge Development Module

Future Technology Devices International Ltd.

The UMFT4222EV is a development module which uses FTDI’s FT4222H, a Hi-Speed USB2.0 to QuadSPI/I2C Bridge in compact 32-pin QFN package. FT4222H requires an external Crystal (12MHz) for the internal PLL to operate. It supports multi-voltage IO, 3.3V, 2.5V or 1.8V. It also provides 128 Bytes one-time-programmable (OTP) memory space for storing vendor specific information. The FT4222H contains SPI/ I2C configurable interfaces. The SPI interface can be configured as master mode with single, dual, or quad bits data width transfer or slave mode with single bit data width transfer. The I2C interface can be configured as master or slave mode.

The UMFT4222EV is supplied as a small PCB which is designed to plug into a standard 0.8” wide 24 pin DIP socket. All components are Pb-free (RoHS compliant).

The UMFT4222EV has the following features:

• Single Hi-Speed USB2.0 chip (FT4222H) to flexible and configurable SPI/I2C interfaces.
• SPI interface support for Single / Dual / Quad SPI Master Mode with configurable target operating speed.
• Up to 28Mbps data transfer rate in SPI mode with quad data mode.
• Support up to 4 slave selection control pins in SPI master mode.
• Support Single SPI Slave Mode with SCK operating frequency up to 20MHz.
• SCK can support up to 40MHz in SPI master.
• I2C interface support 7-bits address and fully compatible to v2.1 and v3 specification for I2C Master/Slave Mode with configurable target operating speed for 100kbit/S standard mode, 400kbit/S fast mode 1Mbit/S Fast mode plus and 3.4Mbit/S high speed mode.

• Configurable GPIOs controlled by application software via USB bus.
• Fully support USB2.0 suspend/resume and remote wakeup.
• Support Battery Charger Detection.
• OTP memory inside for USB Vendor ID (VID), Product ID (PID), device serial number, product description string and various other vendor specific data.
• USB Power Configurations; bus-powered and self-powered.
• On board jumper for FT4222H configuration mode, USB power configuration and VCCIO source selection.
• Integrated power-on-reset circuit.
• True 3.3V CMOS drive output and TTL input. (operates down to 1.8V with external 1.8V power input to VCCIO.
• USB2.0 Low operating and suspend current; 68mA (active-typ.) and 375uA (suspend-typ).
• Configurable I/O pin output drive strength: 4 mA(min) and 16 mA(max).
• UHCI / OHCI / EHCI / XHCI host controller compatible.
• FTDI’s royalty-free Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
• Supplied PCB designed to fit a standard 20.2mm (0.8”) wide 24 pin DIP socket. Pins are on a 2.54mm (0.1”) pitch.
• On board USB Micro-B receptacle allows module to be connected to a PC.

1.1 Driver Support
Royalty free D2XX Direct Drivers are available for the following Operating Systems (OS):
• Windows
• Linux
• Mac
• Android (J2xx / D2xx only)

See the following website link for the full driver support list including OS versions and legacy OS.

Drivers - FTDI

D2XX Direct Drivers allow direct access to the USB device through a DLL. Application software can access the USB device through a series of DLL function calls. A support library for FT4222H, LibFT4222, must be used in conjunction with D2XX and provides high-level and convenient APIs (Application Programming Interface) to speed up user application development. For further details refer to AN_329 User Guide for LibFT4222.

User Guide for LibFT4222

Example code is also provided with the LibFT4222 download. Some D2xx direct functions can be used too. Refer to Appendix B – D2XX API support of AN_329 User Guide for LibFT4222 and reference the D2XX Programmer’s Guide document for details of those APIs which is available from the Documents section of our website.
