Overview
R7FS124773A01CNB#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 BC 1.2), CAN 2.0B, dual I²C, dual SPI, three SCI interfaces, 14-bit ADC (18 channels), 12-bit DAC, CTSU capacitive touch sensing, and hardware AES-128/256 encryption - deployed in industrial HMI, smart sensor nodes, and battery-powered USB-CAN gateways.
For engineers reviewing the R7FS124773A01CNB#AA1 datasheet, R7FS124773A01CNB#AA1 pinout, R7FS124773A01CNB#AA1 application, or R7FS124773A01CNB#AA1 equivalent, this page delivers verified technical context, package-specific pin mapping, safety-certifiable peripherals (CAC, IWDT, SRAM parity), and real-world selection guidance for automotive-grade temperature range (–40°C to +105°C) embedded control.
Technical Context
This MCU implements a single-core Arm Cortex-M0+ (Armv6-M, r0p1-00rel0) executing at up to 32 MHz with SysTick timer driven by LOCO or ICLK, DWT/BPU debug support, and CoreSight MTB-M0+ trace. It integrates dual watchdogs (WDT and independent IWDT), register write protection, and SRAM parity checking for functional safety compliance.
The peripheral set includes a USBFS module with on-chip transceiver and 3.3-V LDO regulator, CAN controller supporting 11-/29-bit IDs and 32 mailboxes, and event-driven architecture via ELC linking AGT, GPT, ADC, and communication interrupts without CPU intervention - enabling deterministic low-latency response in motor control and real-time sensor fusion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS124773A01CFM | LQFP-64 package (10 mm × 10 mm, 0.5 mm pitch); identical electrical specs and feature set. | Better suited for through-hole prototyping and manual rework; larger footprint eases thermal management in high-current designs. | Select when PCB assembly uses LQFP-compatible tooling or requires higher thermal dissipation than QFN allows. |
| R7FS124773A01CNE | 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch); 32 I/O pins vs. 48; reduced CTSU channel count (23 vs. 31). | Targeted at space-constrained consumer electronics where USB/CAN coexistence is retained but touch channel density is lower. | Choose for cost-sensitive, size-limited applications where full 48 I/O and 31 CTSU channels are unnecessary. |
Compared with R7FS124773A01CFM and R7FS124773A01CNE, the R7FS124773A01CNB#AA1 offers optimal balance of compact 64-pin QFN packaging, full I/O count, and maximum CTSU channel availability - making it the preferred choice for production-ready industrial gateways requiring both USB and CAN in minimal board area.

FAQ
What is the operating temperature range for the R7FS124773A01CNB#AA1?
The R7FS124773A01CNB#AA1 is rated for industrial operation from –40°C to +105°C, validated per JEDEC JESD22-A108 and qualified for continuous use in automotive under-hood and factory-floor environments. This rating applies specifically to the 64-pin QFN package variant (PWQN0064LA-A) and is documented in Table 1.13 of the R01DS0264EU0140 datasheet.
Does the R7FS124773A01CNB#AA1 support USB device enumeration without external components?
Yes, the R7FS124773A01CNB#AA1 integrates a USB 2.0 Full-Speed transceiver with internal 3.3-V LDO regulator and supports full-speed device enumeration using only a 1.5-kΩ pull-up resistor on USB_DP. No external PHY or level-shifter is required, and BC 1.2 charging port detection is handled entirely in hardware.
How many capacitive touch channels does the R7FS124773A01CNB#AA1 support?
The R7FS124773A01CNB#AA1 supports up to 31 capacitive touch sensing channels via its integrated CTSU, as confirmed in Table 1.14 of the datasheet. This count is specific to the 64-pin package variants (CNB and CFM) and enables multi-button, slider, and proximity sensing in a single-chip solution.
Is AES encryption supported in the R7FS124773A01CNB#AA1 with orderable suffix AA1?
Yes, the R7FS124773A01CNB#AA1 includes full hardware AES-128 and AES-256 acceleration, unlike earlier AA0/AC0 suffix variants which have restricted AES functionality. This is explicitly stated in the Technical Update TN-SY*-A024A/E and confirmed in the R01DS0264EU0140 Rev.1.40 datasheet footnote on page 9.
What is the maximum number of CAN mailboxes supported by the R7FS124773A01CNB#AA1?
The R7FS124773A01CNB#AA1 supports up to 32 configurable CAN mailboxes, with flexible assignment between transmit and receive roles in normal or FIFO mode.
