Overview
Description
As a CPU board usable in connection with the on-chip debugging emulators E2 and E2 Lite, the RL78/F22 (R7F122FGG) target board enables simple and easy evaluation of the RL78/F22 MCU.
Note: This board comes with two touch buttons for simple evaluation, but when designing an actual board, please check the Capacitive Sensor Microcontrollers CTSU Capacitive Touch Electrode Design Guide and use the RL78/F22 capacitive touch evaluation system (RSSK-RL78F22) for evaluation.
Features
- Incorporates RL78/F22 (R7F122FGG)
- 4MHz resonator and 32.768kHz resonator are mounted
- Equipped with universal area (2.54 mm pitch)
- Supports both flash memory programming and on-chip debugging (using TOOL0 pin)
- Highly extendable: peripheral board connectors are equipped with microcontroller pins
- Mounted with two touch buttons using capacitive sensor units

This application note provides the design principles and layout examples of touch electrodes for microcontrollers embedded with a Capacitive Touch Sensing Unit (CTSU). It outlines recommended design practices and considerations for both self‑capacitance and mutual‑capacitance methods, covering electrode geometry, routing, and shielding structures. In addition, it describes the application examples for each sensing method.
