Dusseldorf, December 3, 2013 — Renesas Electronics Europe, a premier provider of advanced semiconductor solutions, and Langer EMV announced today that the RX100 microcontroller family is highly robust against environmental noise. Langer EMV, an independent testing company, acknowledges the exceptional electromagnetic compatibility (EMC) performance of the RX110 MCU. Renesas MCUs’ good EMC performance helps reduce development costs and bill of material cost, as the microcontroller no longer needs to be protected by a specific transient voltage surge suppressor or an expensive multilayer ceramic capacitor.
Langer EMV’s IC test engineer performed burst tests on each pin of the RX110 MCU and ascertained that the port pins’ immunity is high as it overcomes ±300V during the Pulse Voltage Test. The RX110 microcontroller is part of the robust RX microcontroller family, which pushed the testing threshold limit.
One of the most common sources of electrical noise in domestic white goods is inductive components - such as motors, induction rings or relays - through which a current is interrupted. The measurement system devised by Langer EMV enables comprehensive testing of the microcontroller’s response to Electric Fast Transient (burst) tests on each pin. The injected pulse disturbances and voltage spikes reach up +/-510V on the signal pins without disturbing the MCU. Langer EMV has tested the RX110 MCU, a member of the RX100 family, in a 64-pin package, and the test results show a high level of robustness for a microcontroller against spikes and fast transient.
Renesas Electronics Europe focuses on supplying microcontroller-based solutions for a wide range of applications within the digital home such as white goods, small appliances, utility, metering, in-home displays, HVAC, security, healthcare and audio visual. Vincent Mignard, Renesas’ Marketing Engineer for Smart Home, comments: “The electronic content of home appliances is continuing to grow and the environment in which they operate can be subject to a lot of electrical noise. Accordingly, white goods manufacturers are looking increasingly for MCUs that have robust protection against electro-magnetic interference (EMI). The Langer EMV burst tests confirm that the new RX110 microcontrollers are perfectly suited to such applications and are a strong solution to a noisy environment. To decrease on-chip power/ground noise interference, Renesas implemented separated internal power/ground lines. Sensitive MCU pins are equipped with analogue RC filters and the key digital input functions include programmable digital filters.”

About Langer EMV-Technik
Our experience in the field of electromagnetic compatibility (EMC) goes back to 1981. It has its roots in our practical work in the construction of power installations and plants and in the scientific field in close cooperation with the Technical University of Dresden. The company Ingenieurbüro G. Langer was established in 1993 and two years later, in 1995, re-established as Langer EMV-Technik. The company manufactures the newly developed pre-compliance measurement devices and IC-test equipment and sells these on five continents. New information and practical processes regarding EMC are brought to a wider audience through seminars and publications. Since 1990, around 20 German patents and utility models have been registered by engineering office G. Langer and four European patents registered on the general field of “Innovative measurement technology and processes in the area of EMC”. The company's philosophy is aimed at the target group of developers of electronic components and integrated circuits. Development-supporting measurement technology is required to remedy problems of electromagnetic disturbance emission or disturbance immunity in the automotive industry, consumer goods sector, medical technology and mechanical engineering. www.langer-emv.de.
