Product details
Overview
R5F526TBAGFN#50 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 complementary PWM with dead-time control - deployed in HVAC compressors, servo drives, and BLDC motor controllers.
For engineers reviewing the R5F526TBAGFN#50 datasheet, R5F526TBAGFN#50 pinout, R5F526TBAGFN#50 application, or R5F526TBAGFN#50 equivalent, key selection criteria include its 120 MHz real-time PWM timing resolution (260 ps minimum), dual-bank flash for safe firmware updates, IEC60730-compliant safety features (IWDT, oscillation-stop detection, CRC, MPU), and support for simultaneous sampling across three 12-bit A/D units.
Technical Context
The R5F526TBAGFN#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching - enabling deterministic response in closed-loop motor control. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator for fail-safe timing.
Peripheral coordination is managed via Event Link Controller (ELC), allowing 183 internal event signals to trigger timer starts, A/D conversions, or PWM updates without CPU intervention - critical for synchronized multi-axis motion control. The GPTWa timer supports 8-channel 32-bit PWM with synchronous start/stop and phase-counting mode, while HRPWM refines edge placement down to 260 ps at 120 MHz.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBAGFN#50?
The R5F526TBAGFN#50 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. The R5F526TBAGFN#50 sustains full-speed operation across its entire voltage range (2.7–5.5 V) and temperature range (–40°C to +105°C), ensuring consistent timing behavior in demanding inverter applications.
Does the R5F526TBAGFN#50 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBAGFN#50 includes dedicated hardware features required for IEC60730 Class B certification: independent watchdog timer (IWDT) with window function, main clock oscillation-stop detection, CRC calculator (CRCA), memory protection unit (MPU), register write protection, and self-test assist functions for RAM and A/D converters. These are implemented in silicon and documented in the R01DS0407EJ0120 datasheet - no external components are needed to meet baseline Class B requirements.
What PWM resolution does the R5F526TBAGFN#50 achieve, and how is it used in motor control?
The R5F526TBAGFN#50 achieves a minimum PWM edge resolution of 260 ps using its HRPWM circuit, which refines the timing of GPTWa-generated waveforms at 120 MHz. This resolution allows precise dead-time adjustment and gate driver timing calibration - directly reducing electromagnetic interference and torque ripple in 3-phase inverter stages. The R5F526TBAGFN#50 uses this capability in single-phase, 3-phase, and 5-phase complementary PWM modes for PMSM, BLDC, and induction motor drives.
How many A/D converter channels does the R5F526TBAGFN#50 support, and what sampling capability does it offer?
The R5F526TBAGFN#50 supports up to 22 channels across three independent 12-bit A/D units (S12ADH): Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), all with sample-and-hold circuits. It enables simultaneous sampling across all three units - critical for capturing phase currents and DC-link voltage at identical timestamps in field-oriented control. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz, and triggers can be sourced from MTU, GPTW, or ELC events.
What package type and pin count does the R5F526TBAGFN#50 use, and is it RoHS compliant?
The R5F526TBAGFN#50 uses the PWQN0064KF-A package: a 64-pin HWQFN with 9 × 9 mm body, 0.5 mm pitch, and exposed thermal pad. It is lead-free and RoHS compliant per Renesas' standard manufacturing process.
