7.2.2

Pull-Up Resistors for I2C

The circuit board designer is required to place external pull-up resistors (10 k

Ω recommended) on the

SDA & SCL signals (per SMBus 1.0 Specification) to Vcc in order to assure proper operation.

7.3

SMBus Slave Interface

The USB3613 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 K

Ω recommended) on both the SMBDATA and SMBCLK signals. To

disable the SMBus, a pull-down resistor of 10 K

Ω 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 24.

Note: All device configuration must be performed via the Pro-Touch Programming Tool. For additional

information on the Pro-Touch programming tool, contact your local Microchip sales

representative.
