Overview

The MCU integrates multiple series of software- and pin-compatible Arm®-based 32-bit cores that share a common set of

Renesas peripherals to facilitate design scalability and efficient platform-based product development.

The MCU in this series incorporates a high-performance Arm Cortex®-M33 core running up to 80 MHz with the following

features:

● Up to 512 KB code flash memory

● 64 KB SRAM

● Quad Serial Peripheral Interface (QSPI)

● USBFS

● Capacitive Touch Sensing Unit (CTSU)

● Analog peripherals

● Security and safety features

Functional description

Operating modes

Two operating modes:

● Single-chip mode

● SCI/USB/SWD boot mode

Resets

The MCU provides 13 resets.

Low Voltage Detection (LVD)

The Low Voltage Detection (LVD) module monitors the voltage level input to the VCC and

EXLVD pins. The detection level can be selected by register settings. The LVD module consists

of three separate voltage level detectors (LVD0, LVD1, LVD2). LVD0, LVD1, and LVD2 measure

the voltage level input to the VCC and to the EXLVD pins for LVD2. LVD registers allow your

application to configure detection of VCC changes at various voltage thresholds.
