Product details
Overview
R7FS124773A01CFL#AA0 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 2.0B, CTSU capacitive touch sensing, 14-bit ADC, 12-bit DAC, and dual analog comparators - deployed in industrial HMI control panels requiring secure, low-power, mixed-signal operation.
For engineers reviewing the R7FS124773A01CFL#AA0 datasheet, R7FS124773A01CFL#AA0 pinout, R7FS124773A01CFL#AA0 application, or R7FS124773A01CFL#AA0 equivalent, key selection considerations include its 48-pin LQFP package, –40°C to +105°C operating range, USB battery charging compliance, AES-128/256 support (note: AA0 suffix has AES restriction per TN-SY*-A024A/E), and CTSU-based touch interface scalability.
Technical Context
This MCU implements a single-core Arm Cortex-M0+ (Armv6-M, r0p1-00rel0) with SysTick timer driven by LOCO or ICLK, supporting up to 32 MHz operation. 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 error detection.
The peripheral set integrates dual clock domains: one for high-precision timing (MOSC, SOSC, HOCO/MOCO/LOCO with trim) and another for safety-critical functions (CAC for clock accuracy measurement, IWDT with independent oscillator, SRAM parity, register write protection). Communication includes three SCI modules (UART/IIC/SPI), two I2C buses, two SPI channels, one CAN controller (32 mailboxes, standard/extended frames), and USBFS with on-chip transceiver and 5-pipe buffer architecture.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS124773A01CFM#AA0 | 64-pin LQFP, 48 GPIO, higher pin count and I/O density; identical core/peripherals except CTSU electrode count (31 vs 23). | Preferred for designs requiring more analog inputs, CAN+USB+SCI concurrency, or future expansion headroom. | Select when board layout allows larger footprint and additional I/O is needed for complex HMI or multi-sensor integration. |
| R7FS124773A01CNE#AA0 | 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), same pinout mapping as CFL but different package type - no exposed pad in CNE variant per PWQN0048KB-A datasheet. | Better thermal performance and smaller footprint than LQFP; requires rework-compatible soldering process. | Choose for space-constrained designs where thermal management is critical and automated assembly is available. |
Compared with R7FS124773A01CFL#AA0, the CFM offers greater I/O scalability at the cost of board area, while the CNE delivers identical functionality in a thermally superior QFN package - both retain full USB/CAN/CTSU feature parity but differ in mechanical integration and thermal path design.
