Product details
Overview
R5F526TFBDFM#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM with dead-time control. It operates across –40°C to +85°C and supports 5-V tolerant I/O.
For engineers reviewing the R5F526TFBDFM#10 datasheet, R5F526TFBDFM#10 pinout, R5F526TFBDFM#10 application, or R5F526TFBDFM#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM timing resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and IEC60730-compliant safety features for functional safety certification.
Technical Context
The R5F526TFBDFM#10 implements the RXv3 CPU core with single-cycle instruction execution, 32×32→64-bit multiplier, IEEE 754-compliant FPU, and collective register bank save for fast context switching. Its clock system integrates an 8–24 MHz external crystal oscillator, PLL, and dedicated 120 kHz IWDT oscillator - enabling precise timing control for real-time motor control loops.
Peripheral coordination is managed via the Event Link Controller (ELC), which interconnects 183 internal event signals - allowing MTU3d timers, GPTWa PWM units, and S12ADH ADCs to operate synchronously without CPU intervention during sleep modes. The MCU's safety architecture includes MPU, Trusted Memory (TM), register write protection, CRCA, and oscillation-stop detection - all aligned with IEC60730 Class B requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TDDFM#10 | Same RX26T family, identical 100-pin LFQFP package and 512 KB flash, but with 48 KB SRAM (vs. 64 KB) and two 12-bit ADC units (vs. three) - lacks second sample-and-hold unit. | Targeted at cost-optimized motor control where simultaneous 3-channel current sensing is not required - e.g., single-shaft fans or pumps. | Select when full 64 KB SRAM and triple-sample-and-hold ADC are unnecessary; offers lower unit cost with same footprint and pinout. |
| R5F523T6DDFM#10 | RX23T-based part in same 100-pin LFQFP; lower 40 MHz max CPU speed, 256 KB flash, 32 KB SRAM, no HRPWM, and only 1-channel CAN FD - lacks IEC60730 safety features. | Suitable for basic BLDC commutation or low-complexity inverters without FOC or functional safety requirements. | Choose only for legacy designs or non-safety-critical applications where 120 MHz performance, HRPWM, and safety certification are not needed. |
Compared with R5F526TFBDFM#10, the R5F526TDDFM#10 retains identical packaging and peripheral set but trades SRAM and ADC capability for cost reduction, while the R5F523T6DDFM#10 represents a generational downgrade in performance, resolution, and safety compliance - making it unsuitable for new IEC60730-certified designs.
