Product details
Overview
R5F526TBCGFL#50 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 hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.
For engineers reviewing the R5F526TBCGFL#50 datasheet, R5F526TBCGFL#50 pinout, R5F526TBCGFL#50 application, or R5F526TBCGFL#50 equivalent, key selection criteria include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC), and dedicated motor-control peripherals including MTU3d, GPTWa, and HRPWM supporting real-time torque and flux vector control.
Technical Context
The R5F526TBCGFL#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching-critical for deterministic motor control loops. Its clock system supports independent PCLKA (120 MHz), PCLKC (120 MHz for timer/HRPWM reference), and PCLKD (60 MHz for ADC) domains to decouple high-speed PWM timing from analog conversion timing.
Motor-specific peripherals include MTU3d (9-channel 16-bit timer with dead-time compensation and 3-phase PWM), GPTWa (8-channel 32-bit general PWM timer with synchronous start/stop across channels), and HRPWM (4-channel sub-nanosecond edge placement for gate driver timing alignment). All three operate under ELC event linking to eliminate CPU intervention during waveform transitions.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBCGFL#50?
The R5F526TBCGFL#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, enabling fast execution of motor control algorithms such as field-oriented control (FOC) and space-vector modulation (SVM) without compromising real-time responsiveness. The R5F526TBCGFL#50 sustains this performance with no wait states on its 512 KB flash and 64 KB SRAM.
Does the R5F526TBCGFL#50 support IEC60730 functional safety compliance?
Yes, the R5F526TBCGFL#50 includes multiple hardware features certified for IEC60730 Class B compliance: oscillation-stop detection, self-diagnostic A/D converter functions, RAM test assist via DOC, CRC calculator (CRCA), register write protection, and independent watchdog timer (IWDT) with window function. These features reduce external safety monitoring requirements and simplify certification for motor control applications. The R5F526TBCGFL#50 integrates them natively without software overhead.
What PWM capabilities does the R5F526TBCGFL#50 offer for motor control?
The R5F526TBCGFL#50 provides three complementary PWM subsystems: MTU3d (9-channel 16-bit, 3-phase mode), GPTWa (8-channel 32-bit, supports single/3/5-phase modes), and HRPWM (4-channel, 260 ps minimum edge resolution). These operate under shared PCLKC timing and synchronize via ELC events, enabling precise dead-time control, fault-triggered shutdown, and phase-aligned sampling. The R5F526TBCGFL#50 uses these to implement robust inverter gate driving with minimal CPU load.
How many A/D converter channels does the R5F526TBCGFL#50 support, and what is their sampling capability?
The R5F526TBCGFL#50 supports up to 22 A/D converter channels across three 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), all with dedicated sample-and-hold circuits. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz. Sampling can be triggered synchronously by MTU/GPTW timers to align with PWM center/edge points - a capability essential for accurate current reconstruction in motor control. The R5F526TBCGFL#50 leverages this for simultaneous multi-phase current sensing.
What communication interfaces are integrated into the R5F526TBCGFL#50?
The R5F526TBCGFL#50 integrates CAN FD (1 channel, ISO 11898-1:2015 compliant), three RSCI channels with Manchester encoding and HBS support, one RIICa (I²C, up to 400 kbps), one RI3C (I³C SDR mode), one RSPId (SPI, up to 30 Mbps), and four SCI channels with flexible mode selection (asynchronous, SPI/I²C emulation, LIN). These enable robust connectivity to sensors, gate drivers, host controllers, and diagnostic tools. The R5F526TBCGFL#50 uses CAN FD for high-speed motor status reporting and RSPId for high-bandwidth FPGA interfacing in motion control systems.
