Renesas R5F526TBCGFL#10

Overview

R5F526TBCGFL#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, 512 KB on-chip flash, 64 KB SRAM, and integrated 3-phase/5-phase complementary PWM generation. It features CAN FD, dual-bank flash, 12-bit ADC with simultaneous sampling across three units, and hardware-accelerated trigonometric functions (TFUv2) for real-time field-oriented control.

For engineers reviewing the R5F526TBCGFL#10 datasheet, R5F526TBCGFL#10 pinout, R5F526TBCGFL#10 application, or R5F526TBCGFL#10 equivalent, key selection criteria include its 120-MHz GPTWa timer with 10-channel single-phase complementary PWM, 260-ps HRPWM resolution, IEC60730 safety support, and 100-pin LFQFP package with 82 general-purpose I/O pins including 5-V tolerant inputs.

Technical Context

The R5F526TBCGFL#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 deterministic real-time motor control loops. Its clock system integrates PLL-synthesized 120-MHz ICLK, independent IWDT oscillator (120 kHz), and configurable peripheral clocks (PCLKA/PCLKC up to 120 MHz, PCLKB/PCLKD up to 60 MHz).

Motor timing is managed by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both synchronized to PCLKC, with ELC-driven event linking eliminating CPU intervention for PWM-triggered ADC conversions, dead-time compensation, and phase-counting modes - critical for space-vector modulation in 3-phase inverters.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCGFL#10?

The R5F526TBCGFL#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, single-cycle instruction execution, and on-chip memory bandwidth - enabling deterministic real-time control loops essential for motor drive applications. The R5F526TBCGFL#10 sustains this performance with no wait states across its 512 KB flash and 64 KB SRAM.

Does the R5F526TBCGFL#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TBCGFL#10 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, register write protection, independent watchdog timer (IWDT) with window function, and self-diagnostic A/D converter disconnection detection. These are implemented in silicon and documented in the R01DS0407EJ0120 datasheet - no external components needed for baseline compliance.

What PWM configurations does the R5F526TBCGFL#10 support for 3-phase inverter control?

The R5F526TBCGFL#10 supports 3-phase complementary PWM using both MTU3d (2-channel output) and GPTWa (3-channel output), with automatic dead-time insertion and non-overlapping waveform generation. Its HRPWM circuit provides 260-ps edge timing resolution on GPTW0–GPTW3 outputs, enabling precise gate-drive synchronization and reduced electromagnetic interference in high-frequency inverter designs.

How many analog-to-digital converter channels does the R5F526TBCGFL#10 have, and what is their sampling capability?

The R5F526TBCGFL#10 includes three 12-bit S12ADH units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This enables simultaneous sampling across up to 7 channels (Units 0 + 1), critical for real-time current/voltage measurement in 3-phase motor control. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK.

What communication interfaces are integrated into the R5F526TBCGFL#10 for industrial networking?

The R5F526TBCGFL#10 integrates CAN FD (ISO 11898-1:2015 compliant), RIICa (400 kbps I²C/SMBus), RI3C (I3C SDR), RSPId (30 Mbps SPI), and four SCI/RSCI channels with LIN and Manchester encoding support. These interfaces enable robust, multi-protocol connectivity - from high-speed motor feedback (CAN FD) to sensor networks (I²C/I3C) and legacy industrial buses (LIN over RSCI).
