Interface & Connectivity



IO-Link is a standardized, serial, bidirectional point-to-point connection for signal transmission and power supply under any networks, fieldbuses or backplane buses. The CCE4510 is a highly integrated IO-Link Master Phy IC providing two IO-Link compliant channels with 1A peak driving current. The built-in IO-Link hardware frame handler significantly improves application performance by automating most of the lower layer communication tasks. By reducing the microcontroller load, CCE4510 frees up valuable processing bandwidth enabling developers to add greater value by running additional processor-intensive tasks without the need for higher performance microcontrollers. Alternatively, developers can reduce system costs by using less capable microcontrollers without reducing overall performance.

CCE4510 supports a wide supply voltage range from 8V to 32V with integrated overvoltage detection as well as high current and temperature protection. Flexible configuration options are available with a QFN-48 7mm x 7mm package.

CCE4510 provides the perfect solution for 2, 4, 8, and 16-port IO-Link master applications connecting IO-Link compliant industrial sensors and actuators.

For a complete end-to-end system solution, Renesas also provides the CCE4502 IO-Link Device Phy.
