Introduction
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).

FT4222H Features and Enhancement
Functional Integration: The FT4222H is a USB 2.0 Hi-Speed (480Mbits/s) to flexible and configurable
SPI/I2C interfaces device. The FT4222H includes an integrated +1.8V and +3.3V Low Drop-Out (LDO)
regulator and a 12MHz to 480MHz PLL. It also includes Power-On-Reset (POR), VBUS detection with
5V-tolerance and 128 bytes one-time-programmable (OTP) memory which simplifies external circuit design
and reduces external component count.
USB2.0 Hi-Speed Device Controller: The FT4222H integrates a USB protocol engine which controls the
physical Universal Transceiver Macro cell Interface (UTMI) and handles all aspects of the USB 2.0 Hi-Speed
interface. The device contains one control endpoint and 4 IN and OUT endpoint pairs. These endpoints can be
configured to implement up to 4 independent interfaces/applications mapped to I2C+GPIO or SPI+GPIO.
Highly Integrated USB2.0 to Configurable SPI Bridge: The FT4222H provides the bridge function
between a USB2.0 and SPI Master/Slave.
The support library, LibFT4222, based on FTDI’s D2XX driver, enables easy configuration of the SPI as a
master or slave. Operating clock frequency on the SPI bus, clock phase and polarity, transfer data bit width
mode, and the number of slave selection controls are also configurable.
The max SPI interface operating clock can be set up to 30MHz in master mode and 20MHz in slave mode. With
quad mode (4-bits) data bus width, the max data transfer throughput can be up to 28Mbps.
USB to Configurable I2C Controller: The FT4222H also provides the bridge function between a USB2.0 and
an I2C Master/Slave.
The support library, LibFT4222, based on FTDI’s D2XX driver, enables easy configuration of the I2C as either
a master or slave, including target operating speed and bus protocol on I2C bus.
The device can run at common I2C bus speeds, 100kbit/s standard mode (SM), 400 Kbit/s fast mode (FM), 1
Mbit/s Fast mode plus (FM+), and 3.4 Mbit/s High Speed mode (HS). Clock stretching is also supported to
conform to v2.1 and v3.0 of the I2C specification.
Configurable GPIOs: The GPIOs in the FT4222H can be fully controlled by an application utility over USB.
There are 4 GPIO pins that can be configured for different purposes, such as a suspend indicator output, and
remote wake up input.
The signal drive strength and slew rate can be configured via USB vendor commands for different design
needs.
Embedded OTP memory: The internal OTP memory in the FT4222H is used to store USB Vendor ID (VID),
Product ID (PID), device serial number, product description string and various other USB configuration
descriptors. With this embedded OTP memory, the device can store vendor specific information and save BOM
cost. The descriptors can be programmed using the FTDI utility software called FT_PROG, which can be
downloaded from FTDI Utilities on the FTDI website (www.ftdichip.com).
Power management: Fully supports USB2.0 suspend/resume and remote wakeup. The PHY will be put to a
power saving mode and the clock to most of the digital circuits will be stopped when the device is suspended.
Source Power and Power Consumption: The FT4222H is capable of operating at a voltage supply +3.3V or
+5.0V with a nominal operational mode current of 68mA and a nominal USB suspend mode current of 375µA.
This allows greater margin for peripheral designs to meet the USB suspend mode current limit of 2.5mA. An
integrated level converter within the FT4222H allows the interface logic to run at +1.8V, 2.5V or +3.3V. (Note:
External pull-ups are recommended for IO
