Overview
R5F526TBBDFM#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.
For engineers reviewing the R5F526TBBDFM#10 datasheet, R5F526TBBDFM#10 pinout, R5F526TBBDFM#10 application, or R5F526TBBDFM#10 equivalent, key selection criteria include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC), and dedicated motor-control peripherals including MTU3d, GPTWa, and HRPWM supporting real-time dead-time compensation and synchronous A/D triggering.
Technical Context
The R5F526TBBDFM#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in motor control interrupt routines. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator with main-clock oscillation stop detection.
Peripherals are partitioned across four peripheral clocks: PCLKA (up to 120 MHz) for MTU3d/GPTWa/HRPWM/CAN FD, PCLKB (up to 60 MHz) for TMR/CMT/SCI, PCLKC (up to 120 MHz) as counter reference for timers and HRPWM, and PCLKD (up to 60 MHz) for S12ADH ADC operation at 0.9 µs minimum conversion time.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBBDFM#10?
The R5F526TBBDFM#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 16-register bank save function, and on-chip 32-bit multiplier/divider-making it suitable for demanding real-time motor control loops where deterministic latency is critical. The R5F526TBBDFM#10 maintains this speed across its full 2.7–5.5 V supply range.
Does the R5F526TBBDFM#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBBDFM#10 includes dedicated hardware features required for IEC60730 Class B compliance: oscillation-stoppage detection, self-diagnostic A/D converter functions, clock accuracy measurement circuit, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, and CRCA. These are documented in the R01DS0407EJ0120 datasheet and do not require external components-enabling certified safety implementation with minimal software overhead. The R5F526TBBDFM#10 also supports register write protection to prevent accidental corruption of critical control registers.
What PWM configurations does the R5F526TBBDFM#10 support for 3-phase inverter control?
The R5F526TBBDFM#10 supports multiple complementary PWM modes essential for 3-phase inverter control: 10 output channels in single-phase complementary mode, 3 channels in 3-phase complementary mode (via MTU3d), and 2 channels in 5-phase complementary mode (via GPTWa). It also provides hardware dead-time insertion, non-overlapping waveform generation, and synchronous start/stop across all channels. The integrated HRPWM module adds 260 ps timing resolution to GPTWa outputs-enabling precise gate timing for SiC/GaN-based inverters operating above 100 kHz.
How many ADC channels does the R5F526TBBDFM#10 provide, and what is their sampling capability?
The R5F526TBBDFM#10 includes three 12-bit S12ADH ADC units totaling 22 channels: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each unit features dedicated sample-and-hold circuits (3 per unit for Units 0/1), programmable sampling time per channel, and simultaneous triggering via ELC. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz-enabling full 22-channel acquisition in under 20 µs for high-fidelity current/voltage sensing in FOC applications.
What communication interfaces are integrated into the R5F526TBBDFM#10 for industrial connectivity?
The R5F526TBBDFM#10 integrates CAN FD (ISO11898-1:2015 compliant, up to 5 Mbps), 4× SCI, 3× RSCI (with Manchester encoding and HBS), 1× I²C (RIICa, 400 kbps), 1× I³C (RI3C, SDR mode), and 2× RSPI (RSPId and RSPIA). These interfaces support multi-protocol fieldbus bridging, diagnostics over CAN FD, sensor interfacing via I²C/I³C, and high-speed SPI peripheral control-making the R5F526TBBDFM#10 suitable as a central controller in distributed industrial systems without requiring external protocol translators.
