Product details
Overview
R7FS124763A01CFL#AA0 from Renesas is an ultra-low-power 32-MHz Arm® Cortex-M0+ microcontroller with 64-KB code flash, 16-KB SRAM, 14-bit ADC, 12-bit DAC, Capacitive Touch Sensing Unit (CTSU), USB 2.0 Full-Speed with BC1.2 support, CAN 2.0B, and hardware AES/TRNG-designed for industrial HMI, smart sensors, and battery-powered control nodes.
For engineers reviewing the R7FS124763A01CFL#AA0 datasheet, R7FS124763A01CFL#AA0 pinout, R7FS124763A01CFL#AA0 application, or R7FS124763A01CFL#AA0 equivalent, this page delivers verified technical context, package-specific pin mapping, safety-certifiable peripherals (CAC, IWDT, SRAM parity), and real-world use-value for embedded design validation and BOM selection.
Technical Context
This MCU implements a single-core Arm Cortex-M0+ (Armv6-M, r0p1-00rel0) with deterministic 32 MHz operation, DWT/BPU debug, and CoreSight MTB trace. It integrates dual-clock domain timing: GPT32/GPT16 timers for motor control PWM generation and AGT timers for low-power event counting-all coordinated via Event Link Controller (ELC) to eliminate CPU intervention.
Analog subsystem includes ADC14 with 18-channel multiplexing and selectable 12-/14-bit resolution, DAC12 with output amplifier, dual ACMPLP comparators with programmable speed, and on-die temperature sensor (TSN) routed to ADC input. Security relies on dedicated AES128/256 engine and TRNG-though AES functionality is restricted in AA0 suffix parts per Renesas Technical Update TN-SY*-A024A/E.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS124773A01CFL#AA0 | 128-KB flash (vs. 64 KB), identical pinout/package, same peripherals and 105°C rating. | Required for larger firmware images or bootloader + application separation; no hardware redesign needed. | Select when future firmware growth or secure boot partitioning is anticipated - drop-in upgrade path within same LQFP-48 footprint. |
| R7FA2E1A93CFM#AA0 | Arm Cortex-M23 core, 48-MHz max, 128-KB flash, TrustZone security, but no CAN or CTSU; 64-pin LQFP. | Suitable for secure IoT edge nodes needing PSA Certified Level 1, but lacks motor control or touch HMI capability. | Choose only if PSA-level security outweighs CAN/CTSU requirements and PCB layout can accommodate 64-pin LQFP. |
Compared with R7FS124763A01CFL#AA0, R7FS124773A01CFL#AA0 offers double flash capacity with zero layout change, while R7FA2E1A93CFM#AA0 trades CAN/CTSU for TrustZone and higher clock speed - making it unsuitable for industrial HMI or motor control despite its security advantages.

FAQ
What is the maximum operating frequency and core architecture of the R7FS124763A01CFL#AA0?
The R7FS124763A01CFL#AA0 features an Arm Cortex-M0+ core based on the Armv6-M architecture, operating at a maximum frequency of 32 MHz. It implements revision r0p1-00rel0 and includes single-cycle integer multiply, SysTick timer, and CoreSight MTB trace. This architecture delivers deterministic real-time performance with low gate count and power efficiency - ideal for resource-constrained industrial control applications where the R7FS124763A01CFL#AA0 serves as the primary system controller.
Does the R7FS124763A01CFL#AA0 support USB Battery Charging Specification 1.2?
Yes, the R7FS124763A01CFL#AA0 USB 2.0 Full-Speed module fully complies with USB Battery Charging Specification 1.2. Its integrated USB transceiver and internal 3.3-V LDO regulator (powered from VCC_USB_LDO) enable direct charging of connected devices such as smartphones or wearables. This capability is confirmed in Section 24 of the R01DS0264EU0140 datasheet and eliminates the need for external charging ICs in portable or docked applications using the R7FS124763A01CFL#AA0.
What are the memory resources available on the R7FS124763A01CFL#AA0?
The R7FS124763A01CFL#AA0 includes 64-KB on-chip code flash memory, 4-KB data flash memory (rated for 100,000 erase/write cycles), and 16-KB SRAM with even parity protection. The code flash supports secure boot and area protection; data flash enables reliable parameter storage across power cycles. These memory resources are validated in Table 1.2 and Section 37 of the R01DS0264EU0140 datasheet - providing sufficient space for real-time firmware, calibration tables, and runtime buffers in the R7FS124763A01CFL#AA0's target applications.
Is hardware AES encryption fully functional on the R7FS124763A01CFL#AA0?
No - AES functionality is restricted in R7FS124763A01CFL#AA0 due to its AA0 suffix. Per Renesas Technical Update TN-SY*-A024A/E, AA0/AC0 parts lack full AES128/256 engine support. For complete AES capability, Renesas recommends AA1/AC1 suffix variants (e.g., R7FS124763A01CFL#AA1). The R7FS124763A01CFL#AA0 retains TRNG and other security features, but AES-dependent protocols (e.g., TLS 1.2 handshake) require careful validation before deployment.
Which package and pin count does the R7FS124763A01CFL#AA0 use?
The R7FS124763A01CFL#AA0 uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), designated by the "FL" in its part number per Figure 1.2 of the datasheet. It provides 32 general-purpose I/O pins, 3 dedicated input-only pins, 4 pins with 5-V tolerance, and 14 N-ch open-drain outputs. This package is rated for –40°C to +105°C operation and is fully documented in Figure 1.5 (pin assignment) and Table 1.12 of the R01DS0264EU0140 datasheet for the R7FS124763A01CFL#AA0.
