Product details
Overview
R5F526TBDGFM#10 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 high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and includes Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TBDGFM#10 datasheet, R5F526TBDGFM#10 pinout, R5F526TBDGFM#10 application, or R5F526TBDGFM#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash architecture enabling background programming, 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 R5F526TBDGFM#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, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator, enabling precise timing separation between system (ICLK), peripheral (PCLKA–D), and flash (FCLK) domains.
Peripheral integration centers on deterministic timing control: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) operate synchronously with PCLKC up to 120 MHz for PWM generation, while HRPWM achieves 260 ps edge placement resolution via fine-grained delay adjustment of GPTW outputs. The ELC enables interrupt-free inter-module triggering-e.g., MTU timer events directly initiating A/D conversion without CPU intervention.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBDGFM#10?
The R5F526TBDGFM#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables real-time execution of field-oriented control (FOC) algorithms, sensorless position estimation, and communication stack processing-all within strict motor control loop deadlines. The RXv3 core's single-cycle instruction execution and integrated FPU further enhance deterministic timing behavior critical for R5F526TBDGFM#10-based inverters.
Does the R5F526TBDGFM#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBDGFM#10 includes multiple hardware features certified for IEC60730 Class B: oscillation-stop detection, RAM test-assisting function via DOC, CRC calculator (CRCA), register write protection, and independent watchdog timer (IWDT) with windowing. These are documented in the R01DS0407EJ0120 datasheet and require minimal software configuration-enabling faster safety certification for R5F526TBDGFM#10-based motor drives without external safety monitors.
What package type and pin count does the R5F526TBDGFM#10 use?
The R5F526TBDGFM#10 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package (LFQFP) measuring 14 × 14 mm with 0.5 mm pitch. It is rated for –40°C to +105°C operation (G-version), making it suitable for under-hood automotive and industrial environments. This package provides 82 general-purpose I/O pins-including 5-V-tolerant, open-drain, and large-current outputs-supporting direct interface with gate drivers and sensors in R5F526TBDGFM#10-based inverter designs.
How does the HRPWM feature improve motor control precision in the R5F526TBDGFM#10?
The HRPWM (High-Resolution PWM) in the R5F526TBDGFM#10 achieves a minimum timing resolution of 260 ps when operating at 120 MHz-enabling nanosecond-level dead-time adjustment for SiC and GaN power stages. This precision prevents shoot-through in high-switching-frequency inverters and improves current waveform fidelity. HRPWM operates on GPTW0–GPTW3 outputs and is implemented via dedicated delay circuitry, independent of CPU load-ensuring consistent timing accuracy critical for R5F526TBDGFM#10's role in high-efficiency motor drives.
Can the R5F526TBDGFM#10 perform simultaneous sampling across multiple A/D channels?
Yes, the R5F526TBDGFM#10 supports true simultaneous sampling using three independent 12-bit S12ADH units: two with 4-channel sample-and-hold (Units 0 and 1) and one with 14 channels (Unit 2). This allows concurrent acquisition of three-phase current signals and DC-link voltage-essential for accurate field-oriented control. Sampling is triggered synchronously via MTU or GPTW events, ensuring phase-aligned measurements with PWM edges, a capability explicitly confirmed for the R5F526TBDGFM#10 in the R01DS0407EJ0120 datasheet.
