Product details
Overview
R5F526TFBDFN#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, CAN FD interface, and integrated high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and operates across –40°C to +85°C.
For engineers reviewing the R5F526TFBDFN#10 datasheet, R5F526TFBDFN#10 pinout, R5F526TFBDFN#10 application, or R5F526TFBDFN#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.
Technical Context
The R5F526TFBDFN#10 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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both synchronized to PCLKC at up to 120 MHz, HRPWM (4-channel) achieving 260 ps resolution via GPTW0–GPTW3, and POE3D/POEG for hardware fault-driven output disable during overcurrent or oscillation failure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TDDFK#10 | Same RX26T family, 64-pin HWQFN (7×7 mm), 256 KB flash, 48 KB SRAM - smaller footprint, reduced peripheral count (e.g., 48 I/O, no HRPWM). | Suitable for space-constrained, lower-power inverter designs where 3-phase PWM suffices and 5-phase/HRPWM not required. | Select when board area is critical and full 100-pin feature set (e.g., 82 I/O, dual ADC units, CAN FD + I3C) is unnecessary. |
| R5F566TEBDFP#30 | RX66T family, 100-pin LQFP, 160 MHz CPU, 1 MB flash, 256 KB SRAM, enhanced GPTP (not HRPWM), same 3-phase PWM but no 260 ps resolution. | Targets higher-performance servo drives needing faster computation and larger memory, but lacks HRPWM-level timing precision for ultra-low-noise applications. | Choose for applications demanding >120 MHz deterministic processing and larger code/data space, accepting trade-off in PWM edge granularity. |
Compared with R5F526TFBDFN#10, R5F526TDDFK#10 offers compact packaging at the expense of HRPWM and dual-bank flash, while R5F566TEBDFP#30 provides higher clock speed and memory but omits sub-nanosecond PWM control - making R5F526TFBDFN#10 uniquely balanced for cost-sensitive, noise-critical industrial inverters.
