Product details
Overview
R5F526TFBDFN#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 PWM generation with dead-time control.
For engineers reviewing the R5F526TFBDFN#50 datasheet, R5F526TFBDFN#50 pinout, R5F526TFBDFN#50 application, or R5F526TFBDFN#50 equivalent, key selection considerations include its 100-pin LFQFP package, 120 MHz real-time PWM timing resolution (260 ps HRPWM), dual-bank flash for safe firmware updates, IEC60730 safety support, and integrated trigonometric function unit (TFUv2) for fast motor vector control.
Technical Context
The R5F526TFBDFN#50 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-enabling deterministic response in motor control loops. Its clock system supports independent PCLKA (120 MHz), PCLKC (120 MHz for timer/HRPWM reference), and PCLKD (60 MHz for ADC), allowing concurrent high-speed peripheral operation without CPU bottlenecking.
It integrates three complementary PWM subsystems: MTU3d (9-channel 16-bit, 3-phase capable), GPTWa (8-channel 32-bit, 10-channel single-phase/3-channel 3-phase/2-channel 5-phase PWM), and HRPWM (4-channel, 260 ps minimum timing resolution)-all synchronized via ELC to eliminate software latency in sensor-triggered commutation.

The R5F526TFBDFN#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter-enabling deterministic real-time response in motor control applications where R5F526TFBDFN#50 is deployed.
Does the R5F526TFBDFN#50 support CAN FD, and what standard does it comply with?
Yes, the R5F526TFBDFN#50 integrates a CAN FD module compliant with ISO11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps in FD mode. This enables high-bandwidth diagnostics and control messaging in industrial networks where R5F526TFBDFN#50 serves as the primary inverter controller.
What PWM resolution does the R5F526TFBDFN#50 achieve, and how is it implemented?
The R5F526TFBDFN#50 achieves a minimum PWM timing resolution of 260 ps using its 4-channel High-Resolution PWM (HRPWM) circuit, which refines the edge timing of GPTWa-generated waveforms at 120 MHz operation. This precision allows accurate dead-time control for SiC/IGBT gate drivers-critical in R5F526TFBDFN#50-based inverter designs.
How does the R5F526TFBDFN#50 support IEC60730 functional safety compliance?
The R5F526TFBDFN#50 includes dedicated hardware for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist via DOC, CRC calculator (CRCA), independent watchdog timer (IWDTa) with dedicated 120-kHz oscillator, and register write protection. These features are validated in R5F526TFBDFN#50's safety manual and enable certified motor control implementations.
What is the memory configuration of the R5F526TFBDFN#50, and how does dual-bank flash benefit firmware updates?
The R5F526TFBDFN#50 features 512 KB of on-chip code flash organized in a dual-bank structure, 64 KB of SRAM, and 16 KB of reprogrammable data flash. The dual-bank flash allows background programming (BGO) and safe firmware updates-where one bank executes while the other is rewritten-ensuring uninterrupted operation in R5F526TFBDFN#50-based systems during field upgrades.
