Future Technology Devices

International Ltd

FT260

(HID-class USB to UART/I

Bridge IC)

FT260 is a HID-class USB to I

C/UART interface

Device Controller with the following advanced

features:



Single chip USB to UART/I

C bridge with

standard Human Interface Device (HID) class

support

USB2.0 compliant Full Speed device with entire

USB protocol handled on the chip.

Support

USB

HID

corresponding

the

interfaces, I C and UART

Interfaces,

each

on-chip

physical



Fully integrated oscillator PLL with no external

crystal required

On-chip eFUSE for USB Vendor ID (VID),

Product ID (PID), and other vendor specific

parameters.

Unique USB serial number generation engine

and programming path to external EEPROM.

Integrated 5V-3.3V-1.8V level converter for

USB I/O.

+5V USB VBUS detection engine

USB Power Configurations; supports bus-

powered, self-powered and bus-powered with

power switching.

USB2.0 Low operating and suspend current;

24mA (active-typ) and 385µA (suspend-typ).

True 3.3V CMOS drive output and TTL input.

(operates down to 1V8 with external pull-ups)

Multiple I/O operating voltage level +3.3V,

+2.5V, +1.8V

pin output drive strength; 4 mA(min) and 16

mA(max)

Integrated power-on-reset circuit.

USB Battery Charger Detection.

UHCI / OHCI / EHCI / XHCI host controller

compatible.

Extended operating temperature range; -40 to

85⁰C.

Available in compact Pb-free 28 Pin WQFN or

TSSOP packages (RoHS compliant).



Pin configuration of enabling HID interface for

variety of application

HID over I

C specification support

Configurable I

C Master Interface controller

conforming to I

C v2.1 and v3.0 specification.

Support 4 speed modes defined in I C-bus

Specification, standard mode (SM), fast mode

(FM), Fast mode plus (FM+), and High Speed

mode (HS)

Robust FTDI UART controller with hardware and

software flow control

Data transfer rate from 1.2 Kbuad to 12 Mbaud

(RS422, RS485, RS232) at TTL levels

Configurable GPIOs can be easily controlled by

software applications under HID class via the

USB bus
