Drivers and software extension increase security for Profinet IRT

Host drivers and an upgrade of the software environment for the TPS-1 Profinet IRT Device Chip have been announced by Renesas.

The software, based on the latest Profinet standard, simplifies the certification process and speeds up the time-to-market for new Profinet developments, says the company. TPS-1 ready-to-use host drivers for the RX630 and RX231 microcontrollers will also be available, enabling a wider choice of ready-to-use host processors including host processors that support various IoT security features.

The TPS-1 Profinet IRT Device Chip was jointly developed by Phoenix Contact and Siemens for compact IO devices and drives. It is delivered with the bundled, royalty- free Prrofinet IRT stack and free-of-charge development tools from Phoenix Contact Software. It lowers the bill of materials cost for implementing a Profinet IRT interface and speeds time-to-market, says the company. It is will delivered with the latest version of the Phoenix Contact software kit consisting of protocol stack and development tools. Version 1.4 is based on the Profinet specification V2.31 to simplify the certification process. According to the company, the Device Chip achieves the Profinet implementation by dividing its roles between the application chip and the TPS-1 Profinet IRT Device chip.

The new host drivers are designed for the RX630 and RX231 microcontrollers which have low power consumption, suitable for industrial and healthcare devices. The RX231 was designed for IoT security and safety, offering hardware-based safety features for UL and IEC60730. Security features include Trusted Secure, that offers AES encryption, a hardware-based random number generator (RNG) and unique device ID, as well as an access management circuit to prevent unauthorised access to AES, TRNG and crypto-key.

The software kit and host drivers will be available in December and will be delivered with the TPS-1 Profinet IRT Device Chip.
