Renesas R5F526TFDGNE#30

Overview

R5F526TFDGNE#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial inverter applications, 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 12-bit D/A converters. It supports IEC60730 safety compliance and operates across –40°C to +85°C.

For engineers reviewing the R5F526TFDGNE#30 datasheet, R5F526TFDGNE#30 pinout, R5F526TFDGNE#30 application, or R5F526TFDGNE#30 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit A/D units, and Trusted Secure IP Lite encryption support for firmware integrity.

Technical Context

The R5F526TFDGNE#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. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120-kHz oscillator for deterministic timing.

Peripheral coordination is managed via Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts, A/D conversions, or port output changes without CPU intervention-critical for real-time motor phase control and fault response in inverter systems.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFDGNE#30?

The R5F526TFDGNE#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its real-time computational capability for demanding motor control algorithms such as field-oriented control (FOC) and sensorless estimation. The RXv3 core's single-cycle instruction execution and integrated FPU ensure deterministic loop timing critical for sub-microsecond current regulation in the R5F526TFDGNE#30.

Does the R5F526TFDGNE#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFDGNE#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables high-speed diagnostics, firmware updates, and multi-inverter coordination at data rates up to 5 Mbps in the flexible data phase. This capability is essential for industrial automation networks where the R5F526TFDGNE#30 serves as a node controller with time-synchronized actuation.

How many A/D converter channels does the R5F526TFDGNE#30 support, and what is their sampling architecture?

The R5F526TFDGNE#30 supports 22 total 12-bit A/D channels across three independent units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each unit includes dedicated sample-and-hold circuits, enabling true simultaneous sampling across all units. This architecture allows synchronized current and voltage acquisition in motor control applications - a core requirement met by the R5F526TFDGNE#30's design for IEC60730-compliant inverters.

What PWM resolution and complementary output capabilities does the R5F526TFDGNE#30 provide?

The R5F526TFDGNE#30 delivers 260 ps minimum timing resolution via its 4-channel High-Resolution PWM (HRPWM) block, applied to GPTW0–GPTW3 outputs. It supports 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM modes with automatic dead-time insertion. These features directly enable precise gate driving for SiC/GaN inverters - a defining capability of the R5F526TFDGNE#30 in high-efficiency motor drives.

Is the R5F526TFDGNE#30 qualified for IEC60730 Class B compliance, and which built-in functions support it?

Yes, the R5F526TFDGNE#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), A/D disconnection detection, and register write protection. These are documented in Renesas' functional safety manual R01UM0570EJ0100 and validated for use in certified industrial motor control designs - confirming the R5F526TFDGNE#30's role in safety-critical systems.
