Product details
Overview
R5F526T9BDFN#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 hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.
For engineers reviewing the R5F526T9BDFN#10 datasheet, R5F526T9BDFN#10 pinout, R5F526T9BDFN#10 application, or R5F526T9BDFN#10 equivalent, this MCU delivers deterministic real-time motor control with IEC60730-compliant safety features, dual-bank flash for seamless firmware updates, and simultaneous sampling across three 12-bit A/D units - critical for field-oriented control (FOC) and sensorless BLDC commutation.
Technical Context
The R5F526T9BDFN#10 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and 113 instructions including DSP extensions. Its memory protection unit (MPU) enforces eight configurable regions with 16-byte granularity, while Trusted Memory (TM) restricts code fetch access to protected flash areas.
Real-time motor control is enabled by tightly coupled peripherals: GPTWa timers (8-channel, 32-bit) synchronized to PCLKC at 120 MHz drive complementary PWM outputs; MTU3d provides 9-channel 16-bit timer resources with dead-time compensation and phase-counting; and ELC links 183 internal events without CPU intervention - enabling synchronous A/D trigger, PWM update, and fault response in sub-microsecond latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADFN#10 | Same RX26T family, identical 100-pin LQFP package and 512 KB flash, but with 48 KB SRAM instead of 64 KB. | Limited buffer space for multi-axis FOC or large FFT windows; suitable for single-motor, lower-bandwidth control loops. | Select when application requires only basic 3-phase control without simultaneous multi-sensor processing or extended safety logging. |
| R5F523T7ADNF#30 | RX23T family, 100-pin LQFP, 256 KB flash, 32 KB SRAM, 120 MHz CPU, but lacks HRPWM and I3C interface. | No 260 ps PWM timing resolution; limited to standard 16-bit MTU3 PWM - insufficient for high-frequency SiC gate driving. | Choose for cost-sensitive, legacy-compatible designs where 500 ns PWM resolution suffices and CAN FD is not required. |
Compared with R5F526T9BDFN#10, the R5F526TADFN#10 reduces SRAM by 16 KB but retains identical motor control peripherals and safety features, while the R5F523T7ADNF#30 sacrifices HRPWM, I3C, and data flash endurance to achieve lower unit cost - making the R5F526T9BDFN#10 optimal for next-generation high-efficiency inverter designs requiring deterministic sub-nanosecond timing control.
