Product details
Overview
R5F526TBADFP#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and includes Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TBADFP#10 datasheet, R5F526TBADFP#10 pinout, R5F526TBADFP#10 application, or R5F526TBADFP#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit A/D units, and dedicated hardware acceleration for trigonometric functions (TFUv2) used in field-oriented control.
Technical Context
The R5F526TBADFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching-critical for real-time motor control ISR handling. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent IWDT oscillator, and configurable peripheral clocks (PCLKA–PCLKD) enabling precise timing isolation between PWM generation (PCLKC), ADC sampling (PCLKD), and communication peripherals.
Hardware safety features include MPU-enforced memory protection, register write protection, oscillation-stop detection, CRC calculator (CRCA) with selectable polynomials, and self-diagnostic A/D disconnection detection-all certified for IEC60730 Class B compliance. The ELC enables interrupt-free inter-module coordination (e.g., MTU3d triggering S12ADH conversion), reducing CPU load during high-frequency control loops.

FAQ
What is the maximum operating frequency and core architecture of the R5F526TBADFP#10?
The R5F526TBADFP#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance and supports single-cycle instruction execution, collective register bank save, and a memory protection unit (MPU). This architecture enables deterministic real-time response essential for motor control loops, and the R5F526TBADFP#10 leverages these capabilities for sub-microsecond PWM updates and fast interrupt handling in industrial inverter applications.
Does the R5F526TBADFP#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBADFP#10 includes hardware features certified for IEC60730 Class B compliance: oscillation-stop detection, A/D converter disconnection detection, clock accuracy measurement, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, CRCA, and register write protection. These are implemented in silicon and documented in Renesas' safety manual R01UM0517EJ0100, making the R5F526TBADFP#10 suitable for safety-critical motor control without external supervision circuits.
What PWM configurations does the R5F526TBADFP#10 support for 3-phase inverter control?
The R5F526TBADFP#10 supports 3-phase complementary PWM using both MTU3d (9-channel, 16-bit) and GPTWa (8-channel, 32-bit) timers, with automatic dead-time insertion and non-overlapping waveform generation. It also provides 5-phase complementary PWM (2 channels) and single-phase complementary PWM (10 channels). The integrated HRPWM achieves 260 ps resolution on GPTW0–GPTW3 outputs-critical for precise timing control in SiC-based inverters-and the R5F526TBADFP#10 routes all outputs through POE3D for hardware fault shutdown.
How many A/D converter channels does the R5F526TBADFP#10 have, and can they sample simultaneously?
The R5F526TBADFP#10 includes three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 channels. All three units support hardware-synchronized sampling via shared ADTRGx triggers, enabling true simultaneous acquisition across motor phase currents and DC-link voltage-essential for accurate field-oriented control. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK, and the R5F526TBADFP#10 supports group scan prioritization and digital window comparison for real-time fault detection.
Is the R5F526TBADFP#10 pin-compatible with other RX26T devices like the R5F526TAAFP#10?
No, the R5F526TBADFP#10 is not pin-compatible with the R5F526TAAFP#10. The R5F526TBADFP#10 uses a 100-pin LFQFP (PLQP0100KB-B) package, while the R5F526TAAFP#10 uses an 80-pin LFQFP (PLQP0080KB-B) package. Pin counts, layout, and peripheral mapping differ significantly-especially for PWM outputs, ADC inputs, and communication interfaces-so PCB redesign is required when substituting between these variants. Always verify pinout against the respective datasheet before migration, and note that the R5F526TBADFP#10's full feature set depends on its 100-pin implementation.
