Product details
Overview
R7FS124763A01CFL#AA1 from Renesas is an Arm Cortex-M0+ microcontroller operating at up to 32 MHz, featuring 64 KB code flash, 16 KB SRAM, USB 2.0 Full-Speed with on-chip transceiver and BC1.2 compliance, CAN 2.0B interface, 14-bit ADC (18 channels), and capacitive touch sensing (CTSU) - deployed in industrial HMI control panels requiring low-power, secure, and mixed-signal integration.
For engineers reviewing the R7FS124763A01CFL#AA1 datasheet, R7FS124763A01CFL#AA1 pinout, R7FS124763A01CFL#AA1 application, or R7FS124763A01CFL#AA1 equivalent, this page delivers verified specifications, package mapping to 48-pin LQFP, functional pin roles, safety-certified peripherals (IWDT, CAC, SRAM parity), and two validated alternative parts for migration or sourcing flexibility.
Technical Context
The R7FS124763A01CFL#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. Its memory subsystem includes 64 KB code flash (with area protection), 4 KB data flash (100k erase/write cycles), and 16 KB SRAM with even parity error detection.
Peripherals are orchestrated via Event Link Controller (ELC) for CPU-free inter-module triggering, Data Transfer Controller (DTC) for interrupt-driven transfers, and dual watchdogs (WDT + IWDT) with independent clock sources - enabling fail-safe operation in temperature-monitored industrial nodes compliant with IEC 61508 functional safety requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 32 MHz max - enables deterministic real-time control with <10 ns interrupt latency for motor commutation timing. |
| Memory | 64 KB code flash / 4 KB data flash / 16 KB SRAM - sufficient for bootloader + secure firmware + sensor fusion algorithms in edge nodes. |
| Analog | 14-bit ADC (18 ch) + 12-bit DAC + 2× ACMPLP + TSN - supports precision current/voltage monitoring and closed-loop analog feedback. |
| Connectivity | CAN 2.0B (32 mailboxes), USB FS (BC1.2), 3× SCI, 2× IIC, 2× SPI - enables multi-protocol fieldbus bridging and PC-side configuration. |

Key Features
| Feature | Design Value |
|---|---|
| USB Battery Charging 1.2 support | Enables direct charging of connected devices (e.g., handheld tools) without external charger IC - reduces BOM count and board space. |
| Event Link Controller (ELC) | Hardware-triggered peripheral chaining (e.g., ADC conversion completion → DTC transfer → GPT PWM update) - eliminates CPU polling and jitter in time-critical loops. |
| Low-Power Analog Comparators (ACMPLP) | Configurable speed/power tradeoff (high-speed mode: <1 µs response, low-speed: <100 nA quiescent) - ideal for wake-on-event battery-powered sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS124773A01CFL#AA1 | 128 KB code flash, same 48-pin LQFP package, identical peripherals and pinout. | Supports larger firmware images (e.g., OTA update stack + dual-bank bootloaders) without layout change. | Select when future firmware growth or secure dual-bank updates are required; otherwise R7FS124763A01CFL#AA1 offers optimal cost for fixed-function deployments. |
| R7FA4M1AB3CFP#AA0 | Arm Cortex-M4F core, 48 MHz, 256 KB flash, 32 KB SRAM, no CTSU, different pinout (64-pin LQFP). | Higher compute throughput for DSP-intensive tasks (e.g., FFT-based vibration analysis), but requires PCB redesign and lacks integrated touch sensing. | Choose only if floating-point math or >64 KB code space is mandatory; not a drop-in replacement due to incompatible pin mapping and missing CTSU. |
