Product details
Overview
R5F526TBDGFM#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, and integrated high-resolution PWM (260 ps min. resolution) for precise inverter timing. It supports CAN FD (ISO 11898-1:2015), dual 12-bit A/D converters with simultaneous sampling, and hardware encryption (AES-128/256) - deployed in industrial servo drives and HVAC compressor controllers.
For engineers reviewing the R5F526TBDGFM#50 datasheet, R5F526TBDGFM#50 pinout, R5F526TBDGFM#50 application, or R5F526TBDGFM#50 equivalent, key selection criteria include its 100-pin LFQFP package with 82 GPIOs (2× 5-V tolerant), 3-phase/5-phase complementary PWM capability, IEC 60730 safety support (oscillation detection, RAM test assist, CRC), and Trusted Secure IP Lite for secure firmware updates.
Technical Context
The R5F526TBDGFM#50 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions, and IEEE 754-compliant single-precision FPU. Its clock system integrates an 8–24 MHz external crystal oscillator, PLL (up to 120 MHz), and dedicated 120 kHz IWDT oscillator - enabling independent watchdog operation during deep sleep.
Peripheral synchronization is segmented across four clock domains: PCLKA (up to 120 MHz for MTU3d/GPTWa/HRPWM/CAN FD), PCLKB (up to 60 MHz for SCI/RSCI/RIIC), PCLKC (up to 120 MHz for timer counter references), and PCLKD (up to 60 MHz for S12ADH ADC clock). The ELC enables 183 internal event signals to trigger module operations without CPU intervention - critical for deterministic motor control timing.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBDGFM#50?
The R5F526TBDGFM#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 113 instructions, and integrated 32-bit multiplier/divider - enabling deterministic execution of complex motor control algorithms in real time without pipeline stalls.
Does the R5F526TBDGFM#50 support IEC 60730 Class B compliance out of the box?
Yes, the R5F526TBDGFM#50 includes built-in IEC 60730 Class B compliance features: main clock oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, register write protection, and A/D converter self-diagnostic functions. These capabilities reduce external component count and simplify certification - no additional safety monitor ICs are required for basic Class B implementation.
What package type and pin count does the R5F526TBDGFM#50 use?
The R5F526TBDGFM#50 uses the PLQP0100KB-B package: a 100-pin Low-profile Quad Flat Package measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad. It provides 82 general-purpose I/O pins, including 2× 5-V tolerant inputs and 15 large-current outputs - optimized for high-density motor control PCB layouts with thermal management.
How many A/D converter channels and what resolution does the R5F526TBDGFM#50 offer?
The R5F526TBDGFM#50 integrates three 12-bit S12ADH A/D converter units totaling 22 channels: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). All units support simultaneous sampling triggered by MTU/GPTW events - essential for accurate current reconstruction in field-oriented control of three-phase motors.
What is the role of the Event Link Controller (ELC) in the R5F526TBDGFM#50?
The Event Link Controller (ELC) in the R5F526TBDGFM#50 enables 183 internal peripheral events - such as MTU overflow or GPTW compare-match - to directly trigger actions in other modules (e.g., A/D conversion start or port output toggle) without CPU intervention. This eliminates interrupt latency and ensures deterministic timing for motor control loops running at up to 20 kHz.
