For the quickly expanding IO-Link market, Renesas Electronics Corporation unveiled two semiconductor solutions: the ZSSC3286, a dual-channel resistive sensor signal conditioner IC that is IO-Link ready, and the CCE4511, a four-channel IO-Link master IC.
CCE4511 Four-Channel IO-Link Master IC
With a 500mA driving current per channel, Renesas’ new CCE4511 is reportedly the first four-channel master integrated circuit (IC) for the IO-Link protocol. It offers a number of benefits over two-channel master devices. Compared to rival products, it uses less energy, has a smaller PCB, and needs fewer external components.
The CCE4511 Offers:
- A high-voltage interface along with overvoltage detection and over-current protection.
- To improve application performance, an integrated IO-Link Frame Handler is provided, which automates most of the lower layer communication tasks.
- Reduces the microcontroller (MCU) loads significantly, thus gaining more performance for other tasks, and/or allowing designers to use a less expensive MCU.
- The CCE4511 has an ambient operating temperature of up to 125º C for harsh industrial environments.
- It also supports detection of ready pulses from IO-Link devices, which is required to fulfill the newly defined IO-Link Safety System Extension.
ZSSC3286 Ready, Dual-Channel Resistive Sensor Signal Conditioner IC
For extremely precise amplification, digitization, and sensor-specific correction of sensor signals, the ZSSC3286 is a dual path sensor signal conditioning integrated circuit (SSC). With an integrated IO-Link stack that runs the IO-Link Smart Sensor Profile for digital measuring and switching sensors.
The device works with external voltage-source components and bridge and half-bridge sensors. A 32-bit Arm-based math core that runs a correction algorithm using calibration coefficients kept in a non-volatile, reprogrammable memory is used to digitally compensate for the sensor offset, sensitivity, temperature drift, and non-linearity.
A wide variety of sensors can be applied optimally for a wide range of applications thanks to the customizable, integrated sensor front-end.
The first sensor signal conditioner with an integrated stack that complies with IO-Link is the ZSSC3286. The stack has traditionally been operated by a separate microprocessor. By replacing the MCU, the ZSSC3286 saves money and board space. Additionally, it provides a measurement scheduler for optimal performance, two parallel ADCs with up to 24-bit resolution, and sophisticated system diagnostic features.
IO-Link Sensor Winning Combination
Renesas combining the CCE4511 and ZSSC3286 with additional products from its extensive range of embedded processing, analog, power, and connectivity solutions.
In order to bring an optimized low-risk design to market more quickly, winning combinations are technically tested system designs from devices that are compatible with one another.
To help customers expedite the design process and launch their products faster, Renesas provides over 400 Winning Combinations with a variety of products from the Renesas portfolio.

Growing Popularity of IO-Link
The most common use of the digital communication protocol IO-Link is in applications related to industrial automation. It facilitates smooth communication between sensors, actuators, and other automation system components because it is a standardized technology.
Because of its ease of use, compatibility with current systems, and capacity to deliver real-time data and diagnostics, this technology has grown in popularity in recent years. Additionally, it improves data availability, controls and minimizes wiring, and provides remote configuration and monitoring.
According to market research firm Infogence Global Research, this market is expected to increase at a rate of more than 20 percent annually, reaching approximately USD 34 billion by 2028. Renesas, an instrumental player in industrial automation systems, is dedicated to offering clients cutting-edge IO-Link solutions.
Key Comments
“Our large base of industrial customers has asked us for new solutions to take advantage of the IO-Link protocol,” said Leopold Beer, VP, Connectivity Sensor Division for Renesas. “These two new products both provide industry-leading performance and functionality for IO-Link applications, and we anticipate further offerings for this important market.”
