FT260 HID-CLASS USB TO UART/I2C BRIDGE IC

Version 1.1

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

Parameter

Default Value

Notes

GPIO Weak Pullup/Pulldown

Disable

Enable the weak pullup / pulldown resistor on the pins GPIO0,

GPIO1, GPIO2, GPIO3, GPIO4, and GPIO5. Default is disabled

(without any pull).

GPIO Slew Rate Enable?

Disable

Set the slew rate control for GPIO related pins GPIO0, GPIO1,

GPIO2, GPIO3, GPIO4, and GPIO5. Default is disabled

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.

Interrupt Trigger

Level-high

Define the interrupt trigger type when GPIO3 is set as

INTR/WAKEUP function. The possible settings are: rising edge,

falling edge, level-high, level-low.

Trigger Level Setting

30ms

Interrupt level width select. When the interrupt is set to level

trigger and it exceeds the specified level width, the interrupt

signal will be generated. The level width can be set as 1ms,

5ms and 30ms.

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.

Pin Status During Suspend

No change

During suspend , each digital I/O pin of the FT260 can be set

- No change, keep the original pin function

- tristate

- push low when suspend

- push high when suspend

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.

HID over I²C Option

Not supported

According to Microsoft HID over I²C Protocol Specification, the

following requests are optional:

GET_IDLE/ SET_IDLE supported or not

GET_PROTOCOL/ SET_PROTOCOL supported or not

SET_POWER supported or not

HID over I²C Subclass

No Subclass

The HID subclass description. It can be:

No Subclass

Boot Interface Subclass

HID over I²C Protocol

None

The HID protocol code description. It can be:

None

Keyboard

Mouse
