Renesas R5F526TFDGNE#50

Overview

R5F526TFDGNE#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.

For engineers reviewing the R5F526TFDGNE#50 datasheet, R5F526TFDGNE#50 pinout, R5F526TFDGNE#50 application, or R5F526TFDGNE#50 equivalent, this MCU delivers deterministic real-time motor control with IEC60730-compliant safety features, dual-bank flash for safe firmware updates, and simultaneous sampling across three 12-bit ADC units - critical for field-oriented control (FOC) and sensorless BLDC commutation.

Technical Context

The R5F526TFDGNE#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast interrupt response. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent IWDT oscillator, and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at derived frequencies).

Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) support synchronous PWM output with dead-time insertion and phase-counting; HRPWM provides 260 ps edge placement resolution on GPTW0–GPTW3 outputs; ELC links timer events to ADC triggers without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFDGNE#50?

The R5F526TFDGNE#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This reflects its RXv3 CPU core efficiency, single-cycle instruction execution, and optimized memory subsystem - enabling deterministic real-time motor control loops with sub-10 µs latency. The R5F526TFDGNE#50 sustains full-speed operation across its entire 2.7–5.5 V supply range.

Does the R5F526TFDGNE#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFDGNE#50 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables data rates up to 5 Mbps in the FD data phase while maintaining classical CAN arbitration. The R5F526TFDGNE#50 uses dedicated CAN_TX/CAN_RX pins and supports bit-rate switching, CRC enhancement, and flexible data-length payloads up to 64 bytes.

How many ADC units does the R5F526TFDGNE#50 include, and what is their sampling capability?

The R5F526TFDGNE#50 includes three independent 12-bit S12ADH ADC units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), all supporting simultaneous sampling. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK. The R5F526TFDGNE#50 supports scan modes, digital comparison, self-diagnostic functions, and ELC-triggered conversions - essential for FOC current sensing.

What PWM resolution does the R5F526TFDGNE#50 offer, and how is it achieved?

The R5F526TFDGNE#50 delivers 260 ps minimum PWM edge placement resolution via its High-Resolution PWM (HRPWM) circuit, which fine-tunes rising/falling edges of GPTW0–GPTW3 outputs. This is achieved using a 120 MHz reference clock and fractional delay logic - enabling precise dead-time control for SiC/GaN inverters. The R5F526TFDGNE#50 supports 3-phase, 5-phase, and single-phase complementary PWM topologies with automatic dead-time insertion.

Is the R5F526TFDGNE#50 qualified for IEC60730 safety compliance, and which features support it?

Yes, the R5F526TFDGNE#50 includes hardware features aligned with IEC60730 Class B requirements: oscillation-stop detection, ADC/comparator disconnection detection, clock accuracy measurement, independent watchdog timer (IWDT) with window function, RAM test assist (DOC), CRC calculator (CRCA), and register write protection. These are documented in Renesas' R01DS0407EJ0120 datasheet - the R5F526TFDGNE#50 is designed to simplify certification of motor control appliances.
