FT260 HID-CLASS USB TO UART/I2C BRIDGE IC

Version 1.1

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

Parameter

Default Value

Notes

Power Source

Bus Powered

Define whether the power source is from the USB bus or a local

source.

Max Bus Power Current

100mA

The max power that will be drawn from VBUS when using bus

power. Range from 0~500mA. If the power source is defined as

self-powered, it must be set as 0mA.

Remote Wake Up

Enable

Define if the FT260 supports remote wake up or not.

GPIO2 Function

SUSPOUT_N

The GPIO2 pin can be set as one of the alternative functions:

- GPIO2

- PWREN# (low active), device ready indicator

- TX_LED, UART TX transferring indicator

- SUSPOUT_N, USB suspend low-active indicator.

GPIOA Function

TX_ACTIVE

The GPIOA pin can be set as one of the alternative functions:

- GPIOA

- TX_LED, UART TX transferring indicator

- TX_ACTIVE

GPIOG Function

BCD_DET

The GPIOG pin can be set as one of the alternative functions:

- GPIOG

- PWREN# (low active), device ready indicator

- RX_LED, UART RX receiving indicator

- BCD_DET, Battery Charger Detection indicator

UART Drive Strength

4mA

Adjustable drive strength for UART related pins TXD/RXD,

CTS/RTS, DTR/DSR, TX_ACTIVE. Drive strength can be set as

4mA, 8mA, 12mA and 16mA

GPIO Drive Strength

4mA

Adjustable drive strength for GPIO related pins GPIO0, GPIO1,

GPIO2, GPIO3, GPIO4, and GPIO5. Drive strength can be set as

4mA, 8mA, 12mA and 16mA

BCD_DET Function Disable?

Battery Charger Detection function can be disabled on

BCD_DET pin.

BCD_DET Drive Strength

4mA

Adjustable drive strength for BCD_DET pin. Drive strength can

be set as 4mA, 8mA, 12mA and 16mA

BCD_DET Polarity

Active-high

Set the polarity on BCD_DET pin for indicating battery charge

detected. Default is set as active-high.

Power Saving Mode

Enable

If power saving mode is enable and the FT260 is idle for 5

seconds, it will switch the system clock to 30KHz for saving

power.

HID over I²C address

The I²C slave address of the target HID-over-I²C device. The

address 0h means no HID-over-I²C device connected.

HID over I²C Descriptor

Address

The start address of the descriptor of the target HID-over-I²C

device.

HID over I²C Interrupt

Rising Edge

Define the interrupt trigger type of the target HID-over-I²C

device. It can be: rising edge, falling edge, level-high, level-

low.
