Product details
Overview
R5F526TFDDND#30 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, CAN FD interface, and integrated high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and includes hardware encryption (AES-128/256), FPU, and dual-bank flash for seamless firmware updates.
For engineers reviewing the R5F526TFDDND#30 datasheet, R5F526TFDDND#30 pinout, R5F526TFDDND#30 application, or R5F526TFDDND#30 equivalent, key selection considerations include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit A/D units, and dedicated HRPWM channels for precision motor phase timing - all critical for real-time closed-loop motor drive designs.
Technical Context
The R5F526TFDDND#30 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 integrates PLL-synthesized 120 MHz ICLK, independent PCLKA/PCLKC domains for peripheral timing isolation, and dedicated IWDT oscillator for fail-safe watchdog operation.
Peripheral coordination is managed via the Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts, ADC conversions, or PWM updates without CPU intervention - essential for deterministic timing in field-oriented control (FOC) algorithms. The GPTWa timer unit (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) provide synchronized, dead-time-compensated complementary PWM outputs across up to 10 single-phase, 3 three-phase, or 2 five-phase configurations.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFDDND#30?
The R5F526TFDDND#30 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, including field-oriented control (FOC) and space-vector modulation, with minimal instruction cycles per operation - directly enabling faster current loop updates and improved dynamic response in inverter systems.
Does the R5F526TFDDND#30 support IEC60730 Class B or Class C compliance?
Yes, the R5F526TFDDND#30 includes dedicated hardware features for IEC60730 compliance, including oscillation-stop detection, RAM test assistance via DOC, CRC calculator (CRCA), register write protection, and self-diagnostic functions for the A/D converter and clock accuracy. These capabilities support both Class B and Class C implementations when combined with appropriate software routines and system-level design - verified in Renesas' official safety manual R01UM0570EJ0100.
What PWM configurations does the R5F526TFDDND#30 support for 3-phase motor control?
The R5F526TFDDND#30 supports 3-phase complementary PWM using both MTU3d (9 channels) and GPTWa (8 channels), delivering up to 3 independent 3-phase outputs with automatic dead-time insertion and non-overlapping waveform generation. Its HRPWM module adds 4 channels capable of 260 ps edge placement resolution - enabling precise timing control for SiC/GaN gate drivers and minimizing switching losses in high-frequency inverters.
How many A/D converter channels does the R5F526TFDDND#30 have, and what is their sampling capability?
The R5F526TFDDND#30 includes three independent 12-bit A/D units (S12ADH): Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 channels. All units support simultaneous sampling triggered by a single event - critical for capturing motor phase currents and DC-link voltage concurrently. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz.
Is the R5F526TFDDND#30 pin-compatible with other RX26T group MCUs?
No, the R5F526TFDDND#30 is not pin-compatible with other RX26T variants due to its 100-pin PLQP0100KB-B package - while other members use 32-, 48-, 64-, or 80-pin packages. Pinouts differ across package options, and peripheral channel allocation (e.g., A/D units, PWM outputs) varies by pin count and RAM size. Migration requires PCB redesign and firmware adaptation to match the specific peripheral mapping of the target variant.
