FT260 - HID class USB to UART / I2C Master IC

FTDI's FT260 is an ideal bridge between USB and either UART or I2C peripherals for sensor or human interface peripheral applications. The I2C mode of operation also supports the HID over I2C protocol defined by Microsoft with Windows 8.

Leveraging the advantages of using a standard USB HID class driver which will be already installed in most OS (our other devices are Vendor Class), the FT260 provides an ideal, fast to implement, bridge between USB and either UART or I2C peripherals. The I2C mode of operation will also support the HID over I2C protocol defined by Microsoft with Windows 8 or above.

The FT260 is offered in a small 28 pin (TSSOP or WQFN) package.

Key Features:

  • Full speed HID class USB device
  • I2C Master interface supporting Standard Mode (SM), Fast Mode (FM), Fast Mode Plus (FM+) amd High Speed mode (HS)
  • UART interface supporting 1200-12MBaud
  • 1.8V to 3.3V IO levels supported
  • No external crystal required

FTDI's UMFT260EV1A is a development module for FTDI's FT260, HID-class USB to UART/I²C Bridge IC and is ideal for functionality evaluation and fast development.

The UMFT260EV1A is designed to plug into a standard 0.8" wide 24 pin DIP socket and connects to a host system is via a Micro USB-B connector.

The UMFTPD3A Universal Programmer Module is used to provide an external programming voltage (Vpp) that covers 1.5 to 6.5V to program FTDI development modules and ICs with internal OTP memory or eFUSE (electrical poly-fuse).

The embedded OTP memory or eFUSE in the FTDI chips is used to store USB Vendor ID (VID), Product ID (PID), device serial number, product description string and chip configuration information. Users can store this vendor specific information in the OTP or eFUSE and save the cost of an external EEPROM from the BOM.

The UMFTPD3A assists the user in programming the OTP memory or eFUSE directly through a USB host controller with FTDI's programming software tool, FT_Prog.

The UMFTPD3A is compatible with the FT260/UMFT260EV1A and the FT4222H/UMFT4222EV chips and modules.
