Renesas R5F526TBBGFP#10

Overview

R5F526TBBGFP#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 timers (GPTWa/MTU3d), CAN FD interface, and hardware encryption (AES-128/256). It targets real-time digital power conversion systems requiring precise timing, safety compliance (IEC60730), and secure firmware execution.

For engineers reviewing the R5F526TBBGFP#10 datasheet, R5F526TBBGFP#10 pinout, R5F526TBBGFP#10 application, or R5F526TBBGFP#10 equivalent, this page delivers verified technical context, validated pin functions, confirmed alternative parts with documented differences, and application-specific design value - all derived exclusively from Renesas R01DS0407EJ0120 Rev.1.20 specification data.

Technical Context

The R5F526TBBGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast interrupt response. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent IWDT oscillator (120 kHz), and configurable peripheral clocks (PCLKA–PCLKD) enabling simultaneous high-speed operation of GPTWa (120 MHz), MTU3d (120 MHz), and S12ADH (60 MHz ADCLK).

Motor control capability is anchored by three synchronized timer subsystems: 32-bit GPTWa (8 channels, 10 single-phase/3 three-phase/2 five-phase complementary PWM outputs), 16-bit MTU3d (9 channels, dead-time auto-insertion, phase-counting), and HRPWM (4 channels, 260 ps minimum resolution for edge timing fine-tuning), all coordinated via Event Link Controller (ELC) without CPU intervention.

The R5F526TBBGFP#10 sustains this performance with no wait states across its 512 KB flash and 64 KB SRAM.

Does the R5F526TBBGFP#10 support IEC60730 functional safety compliance?

Yes, the R5F526TBBGFP#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, ADC disconnection monitoring, clock accuracy measurement, independent watchdog timer (IWDT) with window function, RAM test assist (DOC), CRCA, and register write protection. These are documented in Section 1.1 and safety chapter of R01DS0407EJ0120 Rev.1.20 for the R5F526TBBGFP#10.

What PWM capabilities does the R5F526TBBGFP#10 provide for motor control?

The R5F526TBBGFP#10 delivers three-tiered PWM: 32-bit GPTWa (8 channels, 10 single-phase/3 three-phase/2 five-phase complementary outputs), 16-bit MTU3d (9 channels, auto-dead-time), and HRPWM (4 channels, 260 ps minimum resolution). All are synchronized via ELC and support real-time phase counting and trigger coordination - confirmed for R5F526TBBGFP#10 in Tables 1.1–1.2 and Section 1.4 of R01DS0407EJ0120 Rev.1.20.
