Product details
Overview
R5F526TBCGFM#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 PWM generation with dead-time control.
For engineers reviewing the R5F526TBCGFM#50 datasheet, R5F526TBCGFM#50 pinout, R5F526TBCGFM#50 application, or R5F526TBCGFM#50 equivalent, this MCU delivers deterministic real-time motor control with simultaneous sampling across three 12-bit A/D units, 260 ps HRPWM timing resolution, IEC60730-compliant safety features, and Trusted Secure IP Lite encryption - all in a 100-pin LFQFP package rated for –40°C to +105°C operation.
Technical Context
The R5F526TBCGFM#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. Its clock system integrates PLL, 240-kHz LOCO, and 16/18/20-MHz HOCO oscillators, enabling independent scaling of ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains.
Motor control is enabled by tightly coupled peripherals: GPTWa (8-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) support complementary PWM output with automatic dead-time insertion, phase counting, and synchronous A/D trigger generation; HRPWM provides 260 ps fine-tuning of GPTW0–GPTW3 outputs; and ELC enables event-driven inter-module coordination without CPU intervention.

FAQ
What is the maximum operating frequency and CPU architecture of the R5F526TBCGFM#50?
The R5F526TBCGFM#50 features a 32-bit RXv3 CPU core operating at up to 120 MHz, delivering 709 CoreMark performance. It supports single-cycle instruction execution, IEEE 754-compliant single-precision floating-point unit (FPU), and collective register bank save for rapid context switching - all essential for deterministic real-time motor control loops. The R5F526TBCGFM#50 achieves this performance with no wait states on its 512 KB code flash and 64 KB SRAM.
Does the R5F526TBCGFM#50 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBCGFM#50 includes dedicated hardware features required for IEC60730 Class B certification: oscillation-stop detection, A/D converter disconnection monitoring, clock frequency accuracy measurement, independent watchdog timer (IWDT) with window function, CRC calculator (CRCA), memory protection unit (MPU), and register write protection. These functions are documented in Renesas Application Note R01AN3999JJ0100 and enable certified self-test without external components. The R5F526TBCGFM#50 leverages these to reduce safety validation effort.
What PWM capabilities does the R5F526TBCGFM#50 offer for 3-phase inverter control?
The R5F526TBCGFM#50 provides comprehensive 3-phase inverter control via MTU3d (9-channel 16-bit) and GPTWa (8-channel 32-bit) timers, supporting complementary PWM with automatic dead-time insertion, phase-counting mode, and synchronous A/D triggering. It delivers up to 3 independent 3-phase PWM outputs (6 channels), plus HRPWM with 260 ps edge placement resolution on GPTW0–GPTW3 - enabling precise gate driver timing and harmonic mitigation. The R5F526TBCGFM#50 also integrates POEG pins for hardware-fault shutdown.

The R5F526TBCGFM#50 supports 22 total 12-bit A/D channels across three independent S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). All units support simultaneous sampling with dedicated sample-and-hold circuits (3 per unit for Units 0 and 1), 0.9 µs minimum conversion time at 60 MHz ADCLK, and flexible trigger sources including MTU/GPTW events via ELC. This architecture enables synchronized current, voltage, and temperature acquisition critical for FOC algorithms. The R5F526TBCGFM#50 uses this to achieve sub-µs sampling jitter.
