Renesas R5F526TFBGNE#50

Overview

R5F526TFBGNE#50 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 R5F526TFBGNE#50 datasheet, R5F526TFBGNE#50 pinout, R5F526TFBGNE#50 application, or R5F526TFBGNE#50 equivalent, key selection considerations include its 100-pin LFQFP package, 120 MHz PWM timing resolution (260 ps), IEC60730 safety support, on-chip FPU, and dedicated HRPWM channels for high-precision inverter gate driving.

Technical Context

The R5F526TFBGNE#50 implements the RXv3 CPU core with single-cycle instruction execution, 4-Gbyte linear address space, and 113 instructions including DSP and floating-point operations. Its clock system supports PLL multiplication of external 8–24 MHz crystals or internal HOCO (16/18/20 MHz) to achieve 120 MHz ICLK, while PCLKA/PCLKC run at up to 120 MHz for peripheral timing-critical modules like GPTWa and HRPWM.

It integrates two independent PWM subsystems: eight-channel 32-bit GPTWa supporting 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM; plus four-channel HRPWM delivering 260 ps minimum timing resolution for dead-time control and waveform edge fine-tuning. Both are synchronized to PCLKC and linked via ELC for CPU-free event-driven operation.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFBGNE#50?

The R5F526TFBGNE#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This reflects its RXv3 CPU core's optimized pipeline, single-cycle instruction execution, and efficient memory subsystem-enabling deterministic real-time response in motor control loops. The R5F526TFBGNE#50 sustains this performance with no wait states on both 512 KB code flash and 64 KB SRAM.

Does the R5F526TFBGNE#50 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFBGNE#50 includes hardware-assisted IEC60730 Class B compliance features: oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, self-diagnostic A/D and comparator functions, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and require no external components-making R5F526TFBGNE#50 suitable for certified safety-critical motor control designs.

What PWM resolution does the R5F526TFBGNE#50 deliver, and how is it achieved?

The R5F526TFBGNE#50 delivers a minimum PWM timing resolution of 260 ps using its four-channel HRPWM peripheral, which fine-tunes the edge timing of waveforms generated by GPTW0–GPTW3. This is achieved by leveraging the 120 MHz PCLKC clock domain and internal phase-shift logic-enabling precise dead-time control essential for SiC and GaN inverter designs. The R5F526TFBGNE#50 datasheet confirms this value under "High resolution PWM (HRPWM)" in Section 1.1.

Which communication interfaces does the R5F526TFBGNE#50 support for industrial networking?

The R5F526TFBGNE#50 supports CAN FD (ISO11898-1:2015), multiple SCI/RSCI channels (including LIN-capable RSCI9/RSCI11), I2C (RIICa, 400 kbps), I3C (RI3C, SDR mode), and dual RSPI interfaces. These enable robust industrial networking-CAN FD for high-speed actuator control, RSCI with Manchester encoding for home bus systems, and I3C for low-power sensor connectivity-all accessible simultaneously without resource conflict.

What is the package type and thermal specification of the R5F526TFBGNE#50?

The R5F526TFBGNE#50 uses the PLQP0100KB-B package: a 100-pin LFQFP with 14 × 14 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for the G-version operating temperature range of –40°C to +105°C, validated for continuous operation in industrial motor drive enclosures and automotive under-hood environments. This package is explicitly listed in the R01DS0407EJ0120 datasheet on page 1.
