Renesas R8C/3NT Group Overview

Renesas R5F213N7TNBX R5F213N8TNBX R5F213NATNBX R5F213NCTNBX

Overview
The touch key microcontrollers (MCUs) of the R8C/3NT Group from Renesas Electronics are devices incorporating an electrostatic capacitive touch detector into the R8C/3x Series.

Renesas Electronics - R8C/3NT

By integrating on a single chip a touch sensor IC for touch detection and a microcontroller for controlling the system based on the signals received, the R8C/3NT Group specifically meets the following five customer needs:

  • More compact system size, and further smaller WPP package (3 mm × 3mm) for smaller devices
  • System control via I/O ports
  • Touch key connection via touch detection input pins (5-input)
  • Reduced power consumption
  • Improved noise tolerance
