For engineers reviewing the R7FS124763A01CFL#BA1 datasheet, R7FS124763A01CFL#BA1 pinout, R7FS124763A01CFL#BA1 application, or R7FS124763A01CFL#BA1 equivalent, this page delivers verified package mapping (LQFP-100), confirmed peripheral set (USB, SPI, I²C, UART, ADC, PWM), power supply range (2.7–3.6 V), and real-world selection guidance for embedded control applications with USB interface requirements.
Technical Context
The R7FS124763A01CFL#BA1 implements a single-core Arm Cortex-M0+ CPU with TrustZone-enabled memory protection unit (MPU), integrated USB 2.0 FS PHY with internal transceiver, and supports both internal FLL and external crystal oscillator (1–20 MHz) for clock generation. It includes a 12-bit ADC with 16 channels and hardware-accelerated AES-128 encryption.
System-level features include a configurable watchdog timer (IWDT), low-power modes (SNOOZE, DEEP-SLEEP), and on-chip debug via SWD interface compliant with ARM CoreSight™. The MCU integrates Renesas' Synergy Software Package (SSP) middleware stack for USB device class support (CDC, HID, MSC) and secure boot verification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications with USB device capability.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FS124773A01CFL#BA1 | Same S124 family, but with 1 MB Flash and 128 KB SRAM - no change in USB or peripheral set. | Required where larger firmware image size exceeds 512 KB or dual-bank OTA requires >256 KB per bank. | Select only if memory headroom is insufficient; identical pinout and software compatibility via SSP. |
| R7FA4M1AB3CFM#AA0 | RA4M1 series (Arm Cortex-M4F), 256 KB Flash, 32 KB SRAM, USB FS device - lacks hardware AES and has lower analog integration (no DAC). | Suitable for cost-sensitive USB HID or CDC applications where floating-point math or higher CPU throughput is needed, but security and analog features are secondary. | Choose when M4F performance or lower unit cost outweighs need for AES acceleration and dual DACs. |
Compared with R7FS124763A01CFL#BA1, the R7FS124773A01CFL#BA1 offers scalable memory without design changes, while the R7FA4M1AB3CFM#AA0 trades security and analog capability for M4F compute density - making the former ideal for secure industrial gateways and the latter better suited for basic USB peripheral controllers.

FAQ
Does R7FS124763A01CFL#BA1 support USB host functionality?
No, R7FS124763A01CFL#BA1 supports USB 2.0 Full-Speed device mode only - it lacks a USB host controller, OTG transceiver, or VBUS sensing circuitry. The R7FS124763A01CFL#BA1 USB peripheral is strictly device-side and requires connection to a USB host (e.g., PC or embedded Linux host). For host capability, consider the S3 or S5 series MCUs within the Synergy platform.
What is the maximum allowed crystal frequency for R7FS124763A01CFL#BA1 USB operation?
The R7FS124763A01CFL#BA1 requires a crystal between 12 MHz and 20 MHz for USB Full-Speed operation to meet the ±0.25% accuracy tolerance specified in the USB 2.0 specification. A 12 MHz crystal is commonly used and validated in Renesas reference designs; frequencies below 12 MHz do not satisfy USB timing stability requirements.
Is R7FS124763A01CFL#BA1 pin-compatible with other S124 group MCUs?
Yes, R7FS124763A01CFL#BA1 is pin-compatible with all LQFP-100 variants in the S124 group (e.g., R7FS124753A01CFL#BA1, R7FS124773A01CFL#BA1), sharing identical pin assignments, power domains, and peripheral mappings. This allows memory-size scaling without PCB redesign - only flash/SRAM configuration and software build settings require adjustment.
Does R7FS124763A01CFL#BA1 include a hardware TRNG?
No, R7FS124763A01CFL#BA1 does not integrate a True Random Number Generator. It relies on software-based entropy sources (e.g., jitter RNG using system timers) or external entropy injection for cryptographic key generation. For hardware TRNG, consider the S3A7 or RA6T2 series MCUs, which include dedicated TRNG modules compliant with NIST SP 800-90B.
What debug interfaces are supported by R7FS124763A01CFL#BA1?
R7FS124763A01CFL#BA1 supports ARM Serial Wire Debug (SWD) only - using SWDIO and SWCLK pins. It does not support JTAG. Debugging is fully compatible with Renesas E2 Studio, IAR Embedded Workbench, and SEGGER J-Link tools. SWD enables full breakpoint, watchpoint, and memory inspection capabilities at run-time without impacting application performance.
