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.

The MCU in this series incorporates an energy-efficient Arm Cortex®-M23 32-bit core that is particularly well suited for

cost-sensitive and low-power applications, with the following features:

● Up to 128-KB code flash memory

● 16-KB SRAM

● USB 2.0 Full-Speed module (USBFS)

● USB Type-C interface (USBCC)

● 12-bit A/D Converter (ADC12)

● Security features

Functional description

Operating modes

Two operating modes:

● Single-chip mode

● SCI boot mode

Resets

The MCU provides 12 resets (RES pin reset, power-on reset, independent watchdog timer reset,

watchdog timer reset, voltage monitor 0/1/2 resets, SRAM parity error reset, bus master/slave

MPU error resets, CPU stack pointer error reset, software reset).

Low Voltage Detection (LVD)

The Low Voltage Detection (LVD) module monitors the voltage level input to the VCC pin. 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 pin. LVD registers allow your application to configure detection of VCC changes

at various voltage thresholds.
