HID-Class USB controller chip gets dedicated development support

June 23, 2016 // By Graham Prophet
To add support for implementing USB into embedded systems, FTDI Chip has introduced two development and programming, board level products, as well as a new IC.

The UMFTPD3A programmer module is designed for use with the company’s development hardware and ICs containing either internal one-time programmable (OTP) memory or eFUSE logic (which are both used to store USB vendor ID, product ID product description data, etc.), namely the FT260 and FT4222H offerings. It offers assistance to engineers as they carry out programming of the OTP/eFUSE directly through FTDI Chip’s proprietary FT_Prog programming package and provides an external programming voltage (VPP) that covers 1.5 to 6.5V. The on-board micro USB-B type connector facilitates connection of this module to the host system via a standard USB A to micro B cable.


The UMFT260EV1A is a development module that relates to the company’s recently announced FT260Q, HID-class USB bridging IC (which has I ²C and UART bus conversion capabilities). This module will present engineers with a resource for adding connectivity to human machine interfaces and other computing peripherals. It fits a standard 20.32 mm (0.8-inch) wide 24-pin DIP socket, with pins on a 2.54 mm (0.1-inch) pitch. Like the UMFTPD3A, this product has a micro USB-B connector allowing a standard USB A to micro B cable connection to the host systems. In addition to the UMFT260EV1A module, to further expand the scope of the FT260 series, FTDI Chip has also introduced a 28-pin TSSOP packaged version of the IC that will make it more convenient for pick-and-place procedures. The FT260S is USB 2.0 Full Speed compliant (supporting 12 Mbps data rates). It has four I ²C bus speed modes, plus USB battery charger detection. As both the FT260S and FT260Q rely on standard class drivers the installation of vendor-specific drivers can be avoided.
