Product details
Overview
R5F526TBDGND#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, integrated 512 KB code flash, 64 KB SRAM, 16 KB data flash, and hardware-accelerated 3-phase/5-phase complementary PWM generation. It features CAN FD, dual 12-bit A/D converters with simultaneous sampling, 6-channel analog comparators, and Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TBDGND#10 datasheet, R5F526TBDGND#10 pinout, R5F526TBDGND#10 application, or R5F526TBDGND#10 equivalent, this MCU delivers deterministic real-time motor control with 260-ps HRPWM timing resolution, IEC60730-compliant safety functions, and on-chip FPU for sensor fusion and field-oriented control (FOC) algorithms.
Technical Context
The R5F526TBDGND#10 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU - enabling high-efficiency motor vector math. Its clock system integrates PLL, 240-kHz LOCO, and 120-MHz HOCO, with independent PCLKA/PCLKC domains supporting concurrent 120-MHz peripheral operation (MTU3d, GPTWa, HRPWM) and 60-MHz A/D conversion (S12ADH).
Motor control is enabled by tightly coupled peripherals: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa offers 8-channel 32-bit PWM with synchronous start/stop and ELC-triggered A/D conversion; HRPWM refines GPTW0–GPTW3 outputs to 260-ps resolution. Safety is enforced via MPU, register write protection, CRCA, and oscillation-stop detection.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBDGND#10?
The R5F526TBDGND#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficiency in executing real-time motor control algorithms, including field-oriented control (FOC) loops and trigonometric calculations via the integrated TFUv2 unit. The R5F526TBDGND#10 sustains this performance with zero wait-state access to 512 KB on-chip flash and 64 KB SRAM.
Does the R5F526TBDGND#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBDGND#10 includes hardware features required for IEC60730 Class B compliance: memory protection unit (MPU), register write protection, oscillation-stop detection, CRC calculator (CRCA), independent watchdog timer (IWDT) with window function, and self-diagnostic A/D functions. These are documented in the R01DS0407EJ0120 datasheet and enable certified safety firmware development without external components. The R5F526TBDGND#10 itself is not certified, but provides the necessary building blocks.
What PWM resolution and channel count does the R5F526TBDGND#10 offer for motor control?
The R5F526TBDGND#10 delivers 32-bit GPTWa (8 channels), 16-bit MTU3d (9 channels), and 4-channel HRPWM with 260-ps minimum timing resolution at 120 MHz. This enables precise 3-phase, 5-phase, and single-phase complementary PWM generation with hardware dead-time insertion and synchronous start/stop. The HRPWM refines GPTW0–GPTW3 outputs, allowing nanosecond-level gate timing adjustments critical for SiC/GaN inverter efficiency - a capability confirmed in the RX26T Group datasheet section on HRPWM.
How many A/D converter channels and sample-and-hold units does the R5F526TBDGND#10 include?
The R5F526TBDGND#10 includes two 12-bit S12ADH units: Unit 0 (7 channels with 3 sample-and-hold circuits) and Unit 2 (8 channels), totaling 15 analog input channels. Simultaneous sampling across three sample-and-hold circuits allows acquisition of motor phase currents and DC-link voltage within one conversion cycle - essential for accurate torque estimation in FOC. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK, as specified in the R01DS0407EJ0120 datasheet.
What package type and pin count does the R5F526TBDGND#10 use?
The R5F526TBDGND#10 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package (LFQFP) with 14 × 14 mm body size and 0.5 mm pitch.
