SMBus Slave Interface

The USB84604 includes an integrated SMBus slave interface, which can be used to access internal device run time

registers or program the internal OTP memory. SMBus detection is accomplished by detection of pull-up resistors

(10 kΩ recommended) on both the SMBDATA and SMBCLK signals. To disable the SMBus, a pull-down resistor of

10 kΩ must be applied to SMBDATA. The SMBus interface can be used to configure the device as detailed in Section

6.1, "Configuration Method Selection," on page 27.

The application note AN 26.18 SMBus Slave Interface for the USB253x/USB3x13/USB46x4 [ 7] provides additional

information about register definitions. Refer to the product page of the USB84604 on our web site at www.micro-

Note:

All device configuration must be performed via the Microchip Protouch Programming Tool. For additional

information on the Protouch Programming Tool, contact your local Microchip sales representative.
