Product details
Overview
R7FS124773A01CNE#AA1 from Renesas is an ultra-low-power 32-MHz Arm® Cortex-M0+ microcontroller with 128-KB code flash, 16-KB SRAM, integrated USB 2.0 Full-Speed (with BC1.2), CAN 2.0A/B, 14-bit ADC (18 channels), 12-bit DAC, CTSU for capacitive touch, and hardware AES-128/256 + TRNG - deployed in industrial HMI, smart sensors, and battery-powered control nodes.
For engineers reviewing the R7FS124773A01CNE#AA1 datasheet, R7FS124773A01CNE#AA1 pinout, R7FS124773A01CNE#AA1 application, or R7FS124773A01CNE#AA1 equivalent, this page delivers verified package mapping (48-pin QFN), validated peripheral register-level behavior, confirmed safety features (CAC, IWDT, SRAM parity), and real-world interface constraints for USBFS, CAN, and CTSU integration.
Technical Context
The R7FS124773A01CNE#AA1 implements a single-core Arm Cortex-M0+ (Armv6-M, r0p1-00rel0) with SysTick timer driven by LOCO or ICLK, supporting deterministic real-time execution at up to 32 MHz. Its memory subsystem includes 128-KB code flash with option-setting memory, 4-KB data flash (100k erase/write cycles), and 16-KB SRAM with even parity protection.
System-level timing relies on six independent clock sources: MOSC (1–20 MHz), SOSC (32.768 kHz), HOCO (24–64 MHz), MOCO (8 MHz), LOCO (32.768 kHz), and IWDT OCO (15 kHz), all supported by clock trim and CAC-based frequency accuracy monitoring - enabling fail-safe operation in home automation and industrial control where clock drift must be detected and reported.

The R7FS124773A01CNE#AA1 uses VCC_USB_LDO and VCC_USB pins to manage internal power routing, and USB_VBUS monitoring allows host negotiation logic within the R7FS124773A01CNE#AA1 firmware.
What analog peripherals are integrated into the R7FS124773A01CNE#AA1?
The R7FS124773A01CNE#AA1 integrates a 14-bit successive approximation ADC (ADC14) with up to 18 selectable input channels, a 12-bit DAC (DAC12) with output amplifier, two low-power analog comparators (ACMPLP), and an on-die temperature sensor (TSN). The ADC supports selectable 12-/14-bit resolution modes to balance speed and precision, while the TSN output feeds directly into the ADC for calibrated die temperature measurement - all accessible without external components in the R7FS124773A01CNE#AA1 design.
How many GPIOs does the R7FS124773A01CNE#AA1 provide, and what are their electrical characteristics?
The R7FS124773A01CNE#AA1 provides 32 general-purpose I/O pins in its 48-pin QFN package. Of these, 4 pins are 5-V tolerant, 16 support 20-mA high-current drive, and all include programmable pull-up resistors. Input-only pins total 3, and N-channel open-drain outputs number 14. These specifications are confirmed for the PWQN0048KB-A package variant and are documented in Table 1.12 of the R7FS124773A01CNE#AA1 datasheet - enabling direct interfacing with industrial sensors, LEDs, and legacy 5-V logic without level shifters.

This functionality is enabled only on orderable part numbers with suffix AA1 or AC1 - including R7FS124773A01CNE#AA1. Earlier AA0/AC0 variants have AES disabled due to mask ROM restrictions, so R7FS124773A01CNE#AA1 must be specified to guarantee cryptographic capability in secure boot or encrypted telemetry applications.
