Product details
Overview
R5F526TFDGFP#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control, featuring 120 MHz operation, 512 KB on-chip flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and high-resolution PWM with 260 ps timing resolution. It serves as the central real-time controller in brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) inverters.
For engineers reviewing the R5F526TFDGFP#10 datasheet, R5F526TFDGFP#10 pinout, R5F526TFDGFP#10 application, or R5F526TFDGFP#10 equivalent, key selection criteria include its 3-phase complementary PWM capability, dual-bank flash for safe firmware updates, IEC60730 safety features, and support for simultaneous sampling across three 12-bit A/D units - all critical for certified motor drive designs.
Technical Context
The R5F526TFDGFP#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 120 MHz timer and peripheral operation.
It integrates dedicated motor control peripherals: GPTWa (8-channel 32-bit PWM), MTU3d (9-channel 16-bit timer), HRPWM (4-channel 260 ps resolution), and S12ADH (three 12-bit A/D units with simultaneous sampling). Safety is enforced via MPU, Trusted Memory (TM), register write protection, CRCA, and oscillation-stop detection - all aligned with IEC60730 Class B requirements.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFDGFP#10?
The R5F526TFDGFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all verified in the official R01DS0407EJ0120 datasheet. The R5F526TFDGFP#10 sustains this speed across code flash and SRAM with zero wait states.
Does the R5F526TFDGFP#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFDGFP#10 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test assistance via DOC, clock frequency accuracy measurement, independent watchdog timer (IWDT) with windowing, A/D converter disconnection detection, and register write protection. These are documented in the R01DS0407EJ0120 datasheet Section 1.1 and do not require external components to implement basic self-test routines.
What package type and pin count does the R5F526TFDGFP#10 use?
The R5F526TFDGFP#10 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package (LFQFP) measuring 14 × 14 mm with 0.5 mm pitch. This matches the highest-pin-count variant of the RX26T Group and provides 82 general-purpose I/O pins, including 15 large-current outputs and 2 pins with 5-V tolerance - confirmed in Table 1.2 of the R01DS0407EJ0120 datasheet.
How many A/D converter units does the R5F526TFDGFP#10 integrate, and what is their sampling capability?
The R5F526TFDGFP#10 integrates three 12-bit S12ADH A/D converter units: two with 4 channels each (Units 0 and 1, each supporting 3 sample-and-hold circuits), and one with 14 channels (Unit 2). All units support simultaneous sampling triggered by MTU or GPTW events via the Event Link Controller (ELC), enabling synchronized current sensing across all three motor phases - a capability explicitly specified for the 64 KB RAM variant in the R01DS0407EJ0120 datasheet.
What is the resolution and application of the HRPWM module in the R5F526TFDGFP#10?
The HRPWM module in the R5F526TFDGFP#10 delivers a minimum timing resolution of 260 ps when operating at 120 MHz, applied to the GPTWa channels (GPTW0–GPTW3). This enables ultra-fine dead-time adjustment and reduced switching losses in high-frequency inverter designs. The feature is documented in the "High-resolution PWM waveform generation circuit (HRPWM)" section of the R01DS0407EJ0120 datasheet and is unique to the RX26T Group's motor control optimization.
