Overview
R5F526TBAGFM#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 operates across –40°C to +105°C.
For engineers reviewing the R5F526TBAGFM#10 datasheet, R5F526TBAGFM#10 pinout, R5F526TBAGFM#10 application, or R5F526TBAGFM#10 equivalent, key selection criteria include its 100-pin LQFP package, dual-bank flash architecture for seamless firmware updates, 3-phase/5-phase complementary PWM capability, hardware-accelerated trigonometric functions (TFUv2), and Trusted Secure IP Lite encryption engine.
Technical Context
The R5F526TBAGFM#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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent domain clocking (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Peripheral coordination is managed via Event Link Controller (ELC) with 183 internal event signals, allowing timer-triggered ADC conversion, PWM dead-time compensation, and comparator-initiated port output disable without CPU intervention. Safety features include MPU, register write protection, CRCA, oscillation-stop detection, and hardware-assisted RAM testing.

The R5F526TBAGFM#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables execution of complex field-oriented control (FOC) algorithms within sub-microsecond loop times, making the R5F526TBAGFM#10 suitable for high-bandwidth motor control applications such as servo drives and industrial inverters.
Does the R5F526TBAGFM#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBAGFM#10 includes hardware features required for IEC60730 Class B certification: oscillation-stop detection, memory protection unit (MPU), CRC calculator (CRCA), register write protection, RAM test assist (DOC), and self-diagnostic functions for the A/D converter. These capabilities are documented in the R01DS0407EJ0120 datasheet and reduce software development effort for safety-critical motor control applications using the R5F526TBAGFM#10.
What PWM resolution does the R5F526TBAGFM#10 achieve, and how is it implemented?
The R5F526TBAGFM#10 achieves a minimum PWM timing resolution of 260 ps using its dedicated High-Resolution PWM (HRPWM) module, which controls the rising/falling edges of waveforms generated by GPTWa channels 0–3. This resolution is realized at 120 MHz system clock frequency and enables precise gate delay compensation in SiC/GaN inverter designs - a capability confirmed in the RX26T Group datasheet section on HRPWM functionality for the R5F526TBAGFM#10.
Which communication interfaces does the R5F526TBAGFM#10 support for industrial networking?
The R5F526TBAGFM#10 supports CAN FD (ISO 11898-1:2015), I²C (RIICa, up to 400 kbps), I3C (RI3C, SDR mode), SPI (RSPId, up to 30 Mbps), and multiple SCI/RSCI channels with LIN and Manchester encoding. These interfaces provide deterministic, low-latency connectivity for motor control networks - particularly CAN FD for real-time actuator coordination and RSCI with HBS functionality for home appliance bus systems - all natively supported by the R5F526TBAGFM#10 without external transceivers.
What is the flash and SRAM configuration of the R5F526TBAGFM#10?
The R5F526TBAGFM#10 integrates 512 KB of on-chip code flash memory with dual-bank architecture and background operation (BGO) support, plus 64 KB of no-wait SRAM. The flash enables seamless firmware updates during runtime, while the SRAM capacity accommodates real-time control buffers, FFT tables, and safety stack allocations - both memory resources are fully utilized in reference designs for 3-phase PMSM drives using the R5F526TBAGFM#10.
