CY3240 USB-I2C Bridge Guide, Doc. # 001-66660 Rev.*B 17
3. Kit Operation
3.1 Introduction
This chapter provides key information regarding the CY3240 USB-I2C Bridge specifications. It also
gives a brief overview of how to verify that you have set up the kit correctly. The device meets the
requirements of the I2C Specifications for standard and fast speed I2C devices, and supports USB
human interface devices (HID). The bridge is powered by the USB and consumes less than 500 mA.
The device can be configured for several I2C clock rates such as 50 kHz, 100 kHz, and 400 kHz.
The number of devices that can be connected is constrained only by the I2C address limit and phys-
ical ability of the I2C bus. For more details, see the I2C Specifications.
The USB communication function uses two 64-byte packets: one for input data flow and the other for
output data flow. The maximum bandwidth of this configuration is 64 bytes. This is sufficient for most
USB-I2C bridge applications (Figure 3-1).
