The FT4222HQ-T integrated circuit is part of the FT4222 family and is a high-performance multi-interface controller solution. It’s a single channel four port device that combines USB Type-C and PCIe data interfacing as well as I2C/SPI, GPIO, and mixed-signal circuitry.

The FT4222HQ-T is intended for applications connecting a wide range of peripheral devices that require both USB and PCIe connections. It offers automotive grade products, improved industrial temperature operation and integrated ESD protection, allowing customers to leverage the technology they need while maximizing system performance.

FT4222HQ-T integrates USB-C Type-C port controller, PCIe SSD controller and I2C/SPI interface into one device, and can support four independent functions. It is mainly used in various entertainment devices such as automotive multimedia systems, audio systems, TV sets, etc. It helps developers quickly and easily implement a variety of digital connection protocols, such as USB3.1/3.0 Type-C and PCIe Gen3 x4.

The FT4222HQ-T interfaces with four connectors consisting of two USB Type-C ports and two PCIe ports. The two USB ports can be configured to serve as USB host or device ports each. The two PCIe ports can be configured as an x4 PCIe Gen3 host, x4 PCIe Gen3 device, x4 PCIe Gen2 host, or X4 PCIe Gen2 device. It also includes an I2C/SPI master and slave controller, a set of two multi-function GPIO pins, and two sets of analog inputs with programmable gain or attenuation.

The FT4222HQ-T’s USB Type-C ports can be used to connect with Type-C powered peripheral devices, such as the latest smartphones or tablets, as well as a wide range of USB-C digital displays with resolutions up to 4K and beyond. The USB ports are also backward compatible with traditional USB wiring, allowing users to leverage existing USB devices in their systems.

The PCIe ports provide a high-speed connection to internal or externalNVMe SSDs and other peripherals such as a display connector, Gigabit Ethernet, eMMC/UFS, and general purpose Serial Peripheral Interfaces. The FT4222HQ-T also supports high-speed packet-based transaction protocol which enables faster data transfers and lower power consumption.

In addition , FT4222HQ-T can also include mixed-signal circuitry which offers customers a technical flexibility when incorporating advanced system features, such as overcurrent/over-temperature tolerance, power-on reset detection, control over multiple power domains, ESD protection, and more.

FT4222HQ-T provides a low power solution to dramatically reduce system operating power consumption. It supports a low-power sleep and standby mode that provides the flexibility needed to meet the requirements of any system.

In terms of performance, FT4222HQ-T provides outstanding data rates and performance, such as up to 32Gb/s with PCIe Gen3 devices, up to 10Gb/s with USB 3.1 Type-C devices, and up to 5Gbps with USB 2.0 Type-C devices. This offers customers a significant performance boost over slower devices and non-Type-C connections.

Overall, the FT4222HQ-T integrated circuit offers developers a fast, flexible, and cost-effective solution for connecting peripheral devices with their system. It combines the functionality of multiple individual components into a single device to significantly reduce system complexity and cost.
