9 / 61 page  Copyright © Future Technology Devices International Limited 9 FT260 HID-CLASS USB TO UART/I2C BRIDGE IC Version 1.1 Document No.: FT_001272 Clearance No.: FTDI#484 3.3 Pin Description FT260Q Pin No. FT260S Pin No. Pin Name (Function) Type Description 1 5 DEBUGGER I/O Debugging pin. Should be reserved and tied to high 2 6 STEST_RSTN I Chip reset input for test mode. Active low. Should be reserved and tied to high. 3 7 RESETN I Chip reset input. Active low. Can be tied to high if external reset function is not required. 4 8 DCNF0 I Device Interface Configuration Selection bit-0 for the HID interface selection. Refer to Section 5.1 5 9 DCNF1 I Device Interface Configuration Selection bit-1 for the HID interface selection. Refer to Section 5.1 6 10 VCCIO P ** +3.3V/2.5V/1.8V supply voltage. This is the supply voltage for all the I/O ports. This pin shall be connected to VOUT3V3(pin 22/26) when I/O ports are working at 3.3V 7 11 DIO0 ( TX_ACTIVE / TX_LED / GPIOA ) I/O O O I/O DIO0, Digital Input/Output Pin 0. This pin can be configured as one of the following three functions via embedded eFUSE or external EEPROM. TX_ACTIVE is set as the default function to indicate the UART transmitting is active.- TX_LED is set as the LED driving source when data is transmitted on UART TX port. GPIOA, General Purpose I/O. GPIOA is another optional function. 8 12 DIO1 ( GPIOB / RTSN ) I/O I/O O DIO1, Digital Input/Output Pin 1. GPIOB, General Purpose I/O. is set as the default function. RTSN, Request To Send Handshake, can be enabled via a USB command for the UART interface. 9 13 DIO2 ( GPIOE / CTSN ) I/O I/O I DIO2, Digital Input/Output Pin 2. GPIOE, General Purpose I/O. is set as the default function. CTSN, Clear To Send Handshake, can be enabled via a USB command for the UART interface. 10 14 DIO3 ( RXD / GPIOC ) I/O I I/O DIO3, Digital Input/Output Pin 3. RXD, Receive Asynchronous Data Input, is set as default function when the UART interface is selected via {DCNF1, DCNF0}. GPIOC, General Purpose I/O, is set as the default function when UART interface is not configured. 11 15 DIO4 ( TXD / GPIOD ) I/O O I/O DIO4, Digital Input/Output Pin 4. TXD, Transmit Asynchronous Data Output, is set as default when the UART interface is selected via {DCNF1, DCNF0}. GPIOD, General Purpose I/O, is set as default when the UART interface is not configured. 12 16 DIO5 I/O DIO5, Digital Input/Output Pin 5. |
