FT260S

Pin No.

Pin Name

(Function)

Type

Description

pin is a power input pin and should be connected to pin 23 / 27.

VCCIN

P **

+5.0V(or 3.3V) supply voltage In

Power source-in to embedded regulator.

AGND

Analog Ground

FSOURCE

+3.8V supply voltage In

Power source for programming embedded eFUSE. It should be kept

floating or 0V when not in programming mode

VBUS_DET

VBUS detection input. It is a +5.0V tolerant pin

DIO12

( BCD_DET/

RX_LED/

PWREN_N/

GPIOG )

I/O

DIO12, Digital Input/Output Pin 12.

This pin can be configured as one of the following three functions via

embedded eFUSE or external EEPROM.

BCD_DET is the default function as the battery charger detection

indicator output when the device is connected to a dedicated battery

charger port. Polarity can be defined.

RX_LED is as the LED driving source when data is received on UART

RX port.

PWREN_N is as the power enable indicator when FT260 is USB

enumerated. Low active.

GPIOG, General Purpose I/O, is another optional function.

DIO13

GPIOH/

DSRN

I/O

DIO13, Digital Input/Output Pin 13.

GPIOH, General Purpose I/O, is set as the default function

DSRN, Data Set Ready, can be enabled via USB command for UART

interface.

Table 3.1 FT260 Pin Description

**If VCCIN is supplied with 3.3V power input, then VOUT3V3 and VCCIO must also be driven with this

3.3V power source. For details refer to Section 7.3.
