RX130 32-bit Microcontrollers Renesas Electronics RX130 32-bit Microcontrollers are low-power, highly-integrated RX MCUs with enhanced touch key function and 5V operation support. The RX130 MCUs integrate a 36-channel capacitive touch sensor offering advanced noise immunity, sensitivity, and water resistance. As a result, malfunctions have been reduced, and touch keys can now be applied to various materials, such as wood, other than the typical acrylic or glass. The RX130 Touch feature is ideal for consumer electronics applications used in wet environments such as the kitchen or bath.
