The RX140 MCUs feature the latest capacitive touch sensing units, offering customers an enhanced user experience (UX) and user interface (UI). The MCUs fulfill the IEC EN61000-4-3 level 4 (radiated) and EN61000-4-6 level 3 (conducted) capacitive touch noise tolerance requirements. This proves they are less susceptible to electromagnetic noise, allowing the MCUs to detect changes in water level by directly measuring changes in capacitance through high-precision sensing. Built-in multi-scan functionality and automated sensing enable customers to improve sensitivity through simultaneous measurement using multiple electrodes. This allows for automatic touch detection even in standby mode, making it easier for customers to develop interfaces quickly and easily utilizing touchless operation or proximity sensing. As part of Renesas’ RX capacitive touch MCU lineup, the RX140 MCUs allow customers to develop reliable, high-end capacitive touch systems for applications in a variety of environments. These include home appliances such as microwave ovens, refrigerators, and induction heat cooking stoves, as well as manufacturing equipment, building control panels, and devices that can detect remaining quantities of water or powder on surfaces.
“The RX100 Series of ultra-low power MCUs is gaining popularity for the superior scalability it offers as the entry-level model for the RX Family,” said
The RX140 MCUs also features improved peripheral functions. For example, the number of I/O ports has been increased to allow control of more sensors or external components, and CAN communication support for real-time operation has been added. A built-in AES encryption accelerator and true random number generator (TRNG) reduce the risks of security threats such as data leakage or manipulation.
Designed for scalability, the new RX140 MCUs also maintain pin compatibility with the RX130, enabling customers to upgrade while continuing to make use of existing design resources.
