Product details
Overview
R5F526T9BGFN#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 timing resolution.
For engineers reviewing the R5F526T9BGFN#50 datasheet, R5F526T9BGFN#50 pinout, R5F526T9BGFN#50 application, or R5F526T9BGFN#50 equivalent, key selection criteria include its 100-pin LFQFP package, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC, register write protection), dual-bank flash for safe firmware updates, and dedicated HRPWM circuitry enabling precise dead-time control in high-efficiency motor drives.
Technical Context
The R5F526T9BGFN#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 in real-time motor control loops. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator to support deterministic timing across CPU, peripherals, and safety monitors.
Peripheral integration centers on high-resolution timing: GPTWa (8-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) operate at 120 MHz PCLKA/PCLKC, while HRPWM achieves 260 ps edge placement resolution via sub-cycle interpolation of GPTW outputs-enabling nanosecond-level dead-time tuning critical for SiC/GaN inverter gate drivers.

The R5F526T9BGFN#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, on-chip 32-bit multiplier/divider, and barrel shifter-enabling deterministic execution for real-time motor control algorithms without pipeline stalls or wait states.
Does the R5F526T9BGFN#50 support IEC60730 Class B compliance for household appliances?
Yes, the R5F526T9BGFN#50 includes hardware features required for IEC60730 Class B certification: oscillation-stop detection, self-diagnostic A/D converter, clock frequency accuracy measurement, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, CRC calculator (CRCA), and register write protection. These are implemented in silicon-not software libraries-reducing certification effort.
What PWM resolution does the R5F526T9BGFN#50 achieve, and how is it used in motor control?
The R5F526T9BGFN#50 achieves a minimum PWM edge placement resolution of 260 ps using its dedicated HRPWM circuit, which interpolates GPTWa outputs at 120 MHz. This enables nanosecond-accurate dead-time control essential for preventing shoot-through in high-voltage SiC/GaN inverter stages-critical for efficiency and reliability in industrial motor drives.
How does the dual-bank flash architecture benefit firmware updates in the R5F526T9BGFN#50?
The R5F526T9BGFN#50's dual-bank flash allows background programming (BGO) of one bank while executing application code from the other. This enables seamless, zero-downtime firmware updates in deployed equipment-such as field-upgradable motor control parameters or safety patches-without halting real-time operation or requiring external memory.
What communication interfaces are integrated into the R5F526T9BGFN#50 for industrial networking?
The R5F526T9BGFN#50 integrates CAN FD (ISO11898-1:2015 compliant), four SCI channels, three RSCI channels (with Manchester encoding and HBS), one I2C (400 kbps), one I3C, and two RSPI interfaces (up to 30 Mbps). This mix supports deterministic real-time control (CAN FD), legacy serial connectivity (SCI/RSCI), and high-speed peripheral bridging (RSPI/I3C) in industrial automation systems.
