Renesas has introduced the CCE4511 four-channel IO-Link master IC and the ZSSC3286, an IO-Link-ready sensor signal conditioner IC. Widely used in industrial automation, the IO-Link digital communication protocol enables seamless communication between sensors, actuators, and other devices in an automation system.
The CCE4511 four-channel master transceiver delivers 500 mA of drive current per channel. It integrates an IO-Link frame handler to offload lower-layer communication tasks, reducing microcontroller loads. This high-voltage interface IC offers both overvoltage and overcurrent protection and operates at ambient temperatures up to 125°C. It also detects ready pulses from IO-Link devices, supporting the IO-Link Safety System Extension.
With its embedded IO-Link compliant stack, the ZSSC3286 dual-path sensor signal conditioner eliminates the need for an external microcontroller for stack operation. It accurately amplifies, digitizes, and corrects sensor signals, supporting most resistive bridge sensors and external voltage-source elements. A 32-bit Arm-based math core handles digital compensation for offset, sensitivity, temperature drift, and nonlinearity, using a correction algorithm with calibration data stored in reprogrammable nonvolatile memory.
Both the CCE4511 and ZSSC3286 are available now from Renesas and authorized distributors.
