FT260 HID-CLASS USB TO UART/I2C BRIDGE IC

Version 1.1

Document No.: FT_001272 Clearance No.: FTDI#484

The UART provides a transmitter enable control signal (TX_ACTIVE) on the pin DIO0 to assist with

interfacing to RS485 transceivers. The UART can support baud rates from 1.2 Kbaud to 12 Mbaud.

UART in the FT260 functions include:



Full RS232 support



7 or 8 data bits, an optional parity bit and 1 or 2 stop bits support



Baud rate from 1.2 Kbaud to 12 Mbaud support



Baud rate accuracy within +-1.5%



Optional hardware flow control via RTS / CTS and DTR / DSR



Optional software flow control via XON / XOFF characters

I2C Master Controller. I2C (Inter Integrated Circuit) is a multi-master serial bus invented by Philips. I2C

uses two bi-directional open-drain wires called serial data (SDA) and serial clock (SCL). Common I2C bus

speeds are the standard mode (SM) with bit rate up to 100 Kbit/s, fast mode (FM) with the bit rate up to

400 Kbit/s, Fast mode plus (FM+) with the bit rate up to 1 Mbit/s, and High Speed mode (HS) with the bit

rate up to 3.4 Mbit/s. Refer to the I2C specification for more information on the protocol.

The FT260 device can operates as I2C master, and the major functions include:



Fully compatible to v2.1 and v3 specification



7-bit address support



Support 4 speed configurations defined in I2C-bus specification



Support bit rate up to 3Mbit/s



Clock stretching support

GPIOs. The FT260 contains 14 digital function pins. Each pin can be set as I2C/UART related function or

GPIO (General Purpose Input/Output). Some GPIO functions are implemented in the FT260 for various

applications like TX_ACTIVE, TX_LED, RX_LED for UART; SUSPOUT_N, WAKEUP for USB; PWREN and

BCD_DET indicator for power management. GPIO functions can also be directly controlled by applications

over USB via the Control pipe. The drive strength, slew rate control and pull high/low resistors can be

configured in the Vendor Specific Parameters defined in embedded eFUSE or external EEPROM by

FT_PROG.

GPIO functions for each pin in the FT260 include:



DIO0 (pin 7 @ WQFN28) can be configured as TX_ACTIVE, TX_LED, GPIOA



DIO1 (pin 8 @ WQFN28) will be set as GPIOB function by default



DIO2 (pin 9 @ WQFN28) will be set as GPIOE function by default



DIO3

(pin 10 @ WQFN28) will be set as GPIOC function by default when the UART interface in

not enabled



DIO4 (pin 11 @ WQFN28) will be set as GPIOD function by default when the UART interface in

not enabled



DIO5

(pin 12 @ WQFN28) can be set as GPIO0 function when the I2C interface and external

EEPROM are not supported



DIO6

(pin 13 @ WQFN28) can be set as GPIO1 function when the I2C interface and external

EEPROM are not supported



DIO7 (pin 14 @ WQFN28) can be configured as SUSPOUT_N, SUSPOUT, PWREN_N, GPIO2
