Renesas R5F526TFCDFM#30

Overview

R5F526TFCDFM#30 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, and hardware-accelerated 3-phase/5-phase complementary PWM generation. It features CAN FD, dual 12-bit A/D converters with simultaneous sampling, 6-channel analog comparators, and Trusted Secure IP Lite encryption.

For engineers reviewing the R5F526TFCDFM#30 datasheet, R5F526TFCDFM#30 pinout, R5F526TFCDFM#30 application, or R5F526TFCDFM#30 equivalent, key selection criteria include its 120-MHz GPTWa timer with 260-ps HRPWM resolution, IEC60730-compliant safety functions (IWDT, oscillation-stop detection, RAM test assist), and 100-pin LFQFP package with 82 general-purpose I/O pins including 5-V tolerant inputs and large-current outputs.

Technical Context

The R5F526TFCDFM#30 implements the RXv3 CPU core with single-cycle instruction execution, 32×32→64-bit multiplier, 32/32→32-bit divider, and optional single-precision FPU compliant with IEEE 754. Its memory subsystem includes dual-bank code flash enabling background programming and bank-swapping during operation, plus 16 KB data flash rated for 100,000 erase/write cycles.

Real-time control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both synchronized to PCLKC up to 120 MHz, ELC for interrupt-free inter-module event chaining, and POE3D/POEG for hardware-triggered PWM output disable during fault conditions-critical for IGBT gate drive safety in motor drives.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCDFM#30?

The R5F526TFCDFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32×32→64-bit hardware multiplier, and optimized pipeline architecture-enabling deterministic real-time response in motor control loops without software overhead.

Does the R5F526TFCDFM#30 support IEC60730 Class B compliance?

Yes, the R5F526TFCDFM#30 includes multiple hardware features certified for IEC60730 Class B: independent watchdog timer (IWDT) with dedicated 120-kHz oscillator, oscillation-stop detection, CRC calculator (CRCA), DOC-assisted RAM test, memory protection unit (MPU), and register write protection. These are documented in Renesas Application Note R01AN5015JJ0100 and validated per the RX26T Functional Safety Manual.

What package type and pin count does the R5F526TFCDFM#30 use?

The R5F526TFCDFM#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package with 14 mm × 14 mm body size and 0.5 mm pitch. It provides 82 general-purpose I/O pins, including 2×5-V tolerant inputs and 15×large-current outputs-optimized for direct connection to gate drivers and sensors in compact inverter designs.

How many A/D converter channels and units does the R5F526TFCDFM#30 support?

The R5F526TFCDFM#30 supports three independent 12-bit A/D converter units (S12ADH): Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 channels. Units 0 and 1 each include three sample-and-hold circuits for simultaneous sampling-essential for current reconstruction in 3-phase motor control without external analog front-end components.

What is the resolution and timing capability of the HRPWM function in the R5F526TFCDFM#30?

The R5F526TFCDFM#30 integrates 4-channel High-Resolution PWM (HRPWM) capable of controlling rising/falling edges of GPTWa-generated waveforms with a minimum resolution of 260 ps at 120 MHz operation. This enables sub-nanosecond dead-time accuracy and phase alignment critical for SiC/GaN-based inverters operating above 100 kHz switching frequencies.
