Product details
Overview
R5F526TBDDFL#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 resolution.
For engineers reviewing the R5F526TBDDFL#10 datasheet, R5F526TBDDFL#10 pinout, R5F526TBDDFL#10 application, or R5F526TBDDFL#10 equivalent, this MCU delivers deterministic real-time motor timing, IEC 60730-compliant safety features, dual-bank flash for safe firmware updates, and simultaneous sampling across three 12-bit ADC units - critical for field-oriented control (FOC) and sensorless BLDC commutation.
Technical Context
The R5F526TBDDFL#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 during interrupt-driven motor control loops. Its clock system supports PLL-synthesized 120 MHz ICLK with independent PCLKA/PCLKC domains enabling concurrent high-speed peripheral operation - GPTWa timers and HRPWM run at 120 MHz while ADC uses dedicated PCLKD up to 60 MHz.
Motor-specific peripherals include eight 32-bit GPTWa channels supporting single-/3-/5-phase complementary PWM with programmable dead time, nine-channel MTU3d for position capture and encoder interfacing, six-channel analog comparator with reference selection, and three independent 12-bit ADC units (S12ADH) capable of synchronized sampling across 22 total channels - all coordinated via the Event Link Controller (ELC) to eliminate CPU intervention during waveform generation and current sensing.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBDDFL#10?
The R5F526TBDDFL#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, single-cycle instruction execution, and on-chip FPU acceleration - essential for real-time field-oriented control algorithms. The R5F526TBDDFL#10 maintains this performance across its full operating temperature range (–40°C to +85°C).
Does the R5F526TBDDFL#10 support CAN FD, and what standard does it comply with?
Yes, the R5F526TBDDFL#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables data rates exceeding 5 Mbps in the flexible data-rate phase, making the R5F526TBDDFL#10 suitable for high-bandwidth diagnostics and real-time control messaging in automotive and industrial networks.
How many ADC units does the R5F526TBDDFL#10 include, and what is their sampling capability?
The R5F526TBDDFL#10 includes three independent 12-bit S12ADH ADC units totaling 22 input channels, with minimum conversion time of 0.9 µs at 60 MHz ADCLK. Units 0 and 1 each provide three sample-and-hold circuits for simultaneous multi-channel acquisition - a key capability for accurate current sensing in 3-phase motor control. This architecture is confirmed in the R01DS0407EJ0120 datasheet for 64 KB RAM variants like the R5F526TBDDFL#10.
What PWM resolution does the R5F526TBDDFL#10 offer, and how is it achieved?
The R5F526TBDDFL#10 delivers 260 ps minimum resolution via its four-channel High-Resolution PWM (HRPWM) circuit, which fine-tunes the rising/falling edges of waveforms generated by GPTW0–GPTW3. This resolution is achieved at 120 MHz operation and enables precise dead-time control and gate driver delay compensation - critical for SiC and GaN-based inverter designs. The R5F526TBDDFL#10's HRPWM operates independently of main PWM timing, allowing dynamic adjustment without disrupting base carrier frequency.
Is the R5F526TBDDFL#10 qualified for IEC 60730 compliance, and which safety features does it include?
Yes, the R5F526TBDDFL#10 includes dedicated hardware features for IEC 60730 Class B compliance: oscillation-stoppage detection, independent watchdog timer (IWDT) with window function, CRC calculator (CRCA), memory protection unit (MPU), register write protection, and self-diagnostic support for ADC and comparator circuits.
