Product details
Overview
R5F526TBBDND#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and power conversion, featuring 120 MHz operation, 512 KB code flash, 64 KB SRAM, 16 KB data flash, CAN FD interface, and integrated high-resolution PWM with 260 ps timing resolution. It targets inverter-driven industrial motors, servo drives, and digital power supplies requiring real-time control and functional safety support.
For engineers reviewing the R5F526TBBDND#10 datasheet, R5F526TBBDND#10 pinout, R5F526TBBDND#10 application, or R5F526TBBDND#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, IEC60730-compliant self-test features, and hardware encryption (AES-128/256) for secure boot and firmware integrity.
Technical Context
The R5F526TBBDND#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and collective register bank save for fast context switching-critical for deterministic motor control loops. Its clock system supports independent PCLKA (up to 120 MHz), PCLKC (up to 120 MHz for HRPWM/GPTW), and PCLKD (up to 60 MHz for A/D conversion), enabling precise timing isolation between control, PWM, and analog acquisition domains.
It integrates event-linking controller (ELC) to trigger peripheral operations-including MTU3d, GPTWa, and S12ADH-without CPU intervention, reducing latency in closed-loop response. The on-chip Trusted Secure IP Lite provides AES encryption, true random number generation, and key management, while MPU and register write protection enforce memory and configuration safety per 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 |
|---|---|---|---|
| R5F526TBBDFP#30 | Same RX26T family, identical core/peripherals, but in 80-pin LFQFP (PLQP0080KB-B); 64 KB SRAM, 512 KB flash | Fits space-constrained designs where 100-pin footprint is prohibitive; reduced I/O count (62 vs. 82 GPIO) | Select when board layout requires smaller package and fewer analog/comms channels are needed. |
| R5F523T7DDFK#30 | RX23T family; 40 MHz max, 256 KB flash, 32 KB SRAM, no HRPWM or dual-bank flash; supports CAN 2.0 only | Limited to cost-sensitive, lower-performance inverters (e.g., single-phase fans, pumps) without SiC/GaN requirements | Choose for legacy designs or applications not requiring >100 MHz control loop bandwidth or CAN FD. |
Compared with R5F526TBBDND#10, the R5F526TBBDFP#30 offers identical functionality in a compact 80-pin package but sacrifices 20 GPIOs and 2 A/D units, while the R5F523T7DDFK#30 reduces performance headroom and safety feature depth-making it suitable only for non-safety-critical, lower-frequency motor control.
