Product details
Overview
R5F526TFBDNE#10 from Renesas is a 32-bit RXv3 core MCU optimized for motor control and power conversion, operating at up to 120 MHz with 709 CoreMark performance, 512 KB on-chip flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and dual-bank flash for safe firmware updates - deployed in industrial inverters and servo drives.
For engineers reviewing the R5F526TFBDNE#10 datasheet, R5F526TFBDNE#10 pinout, R5F526TFBDNE#10 application, or R5F526TFBDNE#10 equivalent, key selection criteria include 120-MHz real-time PWM timing control, IEC60730-compliant safety features (IWDT, oscillation-stop detection, CRC, RAM test assist), and simultaneous sampling across three 12-bit A/D units for sensorless FOC motor control.
Technical Context
The R5F526TFBDNE#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 in interrupt-heavy motor control loops. Its clock system supports independent PCLKA (120 MHz), PCLKC (120 MHz for HRPWM/GPTW), and PCLKD (60 MHz for ADC) domains enabling precise timing isolation between computation, PWM generation, and analog acquisition.
It integrates dedicated motor control peripherals: GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel, 260 ps resolution) with hardware dead-time insertion, phase-counting, and ELC-triggered synchronous A/D start - all coordinated without CPU intervention via event linking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TDDNE#10 | Same RX26T family, 256 KB flash, 48 KB SRAM, 48-pin HWQFN package (7 × 7 mm) | Limited peripheral count (fewer ADC channels, no HRPWM), reduced I/O (37 pins), lower thermal dissipation | Select when space-constrained designs prioritize footprint over simultaneous sampling or high-resolution PWM. |
| R5F566TEBDFP#30 | RX66T family, 160 MHz, 1 MB flash, 256 KB SRAM, 100-pin LQFP, enhanced FPU and DSP extensions | Higher compute throughput, additional CAN FD channel, larger ADC buffer, but no Trusted Memory or TM target area | Select for complex multi-axis motion control requiring >100 MHz deterministic loop closure and extended safety certification scope. |
Compared with R5F526TFBDNE#10, the R5F526TDDNE#10 reduces cost and size at the expense of simultaneous ADC sampling and HRPWM precision, while the R5F566TEBDFP#30 delivers higher computational headroom and scalability but lacks the integrated Trusted Memory security architecture required for bootloader integrity in certified inverters.
