Product details
Overview
R5F526TFADND#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, integrated 512 KB code flash, 64 KB SRAM, 16 KB data flash, CAN FD interface, and high-resolution PWM with 260 ps timing resolution.
For engineers reviewing the R5F526TFADND#10 datasheet, R5F526TFADND#10 pinout, R5F526TFADND#10 application, or R5F526TFADND#10 equivalent, this MCU delivers deterministic real-time control for 3-phase/5-phase inverters, supports IEC60730 safety compliance, and integrates hardware-accelerated trigonometric functions (TFUv2), AES encryption, and dual-bank flash for safe firmware updates.
Technical Context
The R5F526TFADND#10 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU - enabling fast floating-point math for field-oriented control (FOC) algorithms. Its clock system combines an 8–24 MHz external crystal with PLL multiplication and independent 120 kHz IWDT oscillator for fail-safe timing.
Real-time peripheral coordination is achieved via Event Link Controller (ELC), which interconnects 183 internal signals - allowing MTU3d timers, GPTWa PWM units, and S12ADH ADCs to trigger each other without CPU intervention, even during sleep modes. The HRPWM module synchronizes with GPTW0–GPTW3 to achieve 260 ps edge placement resolution at 120 MHz operation.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFADND#10?
The R5F526TFADND#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficiency in executing real-time motor control algorithms - critical for field-oriented control loops that must complete within sub-microsecond intervals. The R5F526TFADND#10 sustains this speed with no wait states across its 512 KB flash and 64 KB SRAM.
Does the R5F526TFADND#10 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFADND#10 includes hardware features required for IEC60730 Class B: memory protection unit (MPU), register write protection, oscillation-stop detection, CRC calculator (CRCA), self-diagnostic ADC, and analog input disconnection detection. These reduce software certification burden - the R5F526TFADND#10 is validated in Renesas' Functional Safety Package for RX MCUs, enabling faster qualification of end equipment.
What PWM resolution does the R5F526TFADND#10 achieve, and how is it implemented?
The R5F526TFADND#10 achieves a minimum PWM edge placement resolution of 260 ps using its High-Resolution PWM (HRPWM) module, synchronized to GPTW0–GPTW3 timers running at 120 MHz. This resolution is realized through fine-grained counter interpolation - not fractional-N synthesis - and is verified under actual operating conditions with temperature and voltage variation. The R5F526TFADND#10 uses this capability to minimize dead-time uncertainty in SiC/GaN gate drivers.
How many ADC channels does the R5F526TFADND#10 support, and what sampling architecture does it use?
The R5F526TFADND#10 supports 22 total 12-bit ADC channels across three S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), each with dedicated sample-and-hold circuits. This architecture enables true simultaneous sampling of up to six analog inputs - essential for capturing three-phase motor currents without phase skew. The R5F526TFADND#10 achieves 0.9 µs minimum conversion time per channel when ADCLK runs at 60 MHz.
Is the R5F526TFADND#10 pin-compatible with other RX26T group MCUs?
No, the R5F526TFADND#10 is not pin-compatible with other RX26T variants due to its 100-pin PLQP0100KB-B package - the largest in the group. Smaller variants (e.g., 64-pin PWQN0064KF-A or 48-pin PWQN0048KC-A) have different pin counts, I/O allocations, and peripheral mappings. Migration requires PCB redesign, though software reuse is supported via Renesas' common RX family toolchain and driver libraries for the R5F526TFADND#10.
