Renesas R5F526TFAGNE#10

Overview

R5F526TFAGNE#10 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, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps timing resolution.

For engineers reviewing the R5F526TFAGNE#10 datasheet, R5F526TFAGNE#10 pinout, R5F526TFAGNE#10 application, or R5F526TFAGNE#10 equivalent, key selection considerations include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC calculator), and dedicated HRPWM circuitry enabling precise dead-time control in high-efficiency motor drives.

Technical Context

The R5F526TFAGNE#10 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-critical for real-time motor control loops. Its clock system supports independent PCLKA (up to 120 MHz), PCLKC (up to 120 MHz for timer reference), and PCLKD (up to 60 MHz for ADC) domains, enabling concurrent high-speed computation, PWM timing, and analog acquisition.

It integrates three synchronized peripheral subsystems: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) for multi-phase PWM generation with automatic dead-time insertion and phase-counting; S12ADH (three 12-bit ADC units) supporting simultaneous sampling across up to 22 channels; and CAN FD (ISO 11898-1:2015 compliant) with message filtering and error handling for robust fieldbus communication.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFAGNE#10?

The R5F526TFAGNE#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark, measured under standard conditions per EEMBC methodology. This performance enables real-time execution of complex motor control algorithms such as field-oriented control (FOC) and model predictive control (MPC) without external acceleration. The RXv3 core's single-cycle instruction execution and collective register bank save further reduce interrupt latency in the R5F526TFAGNE#10.

Does the R5F526TFAGNE#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFAGNE#10 includes built-in IEC60730 Class B compliance features: oscillation-stop detection, independent watchdog timer (IWDT) with window function, CRC calculator (CRCA), memory protection unit (MPU), register write protection, and self-test functions for ADC disconnection and clock accuracy. These capabilities are documented in Renesas Application Note R01AN5019JJ0100 and eliminate the need for external safety monitors when properly configured in the R5F526TFAGNE#10.

What ADC architecture does the R5F526TFAGNE#10 use, and how many channels support simultaneous sampling?

The R5F526TFAGNE#10 integrates the S12ADH 12-bit ADC with three independent units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). All three units can sample simultaneously - enabling true concurrent acquisition of phase currents, DC-link voltage, and temperature in motor control applications. Minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz.

Can the R5F526TFAGNE#10 generate 5-phase complementary PWM waveforms, and what is the timing resolution?

Yes, the R5F526TFAGNE#10 supports 5-phase complementary PWM using its GPTWa timer and HRPWM circuit, delivering 2 output channels in 5-phase mode. The HRPWM achieves a minimum timing resolution of 260 ps at 120 MHz operation - enabling precise dead-time control critical for SiC and GaN inverter designs. This capability is confirmed in Section 1.1.2 of R01DS0407EJ0120 and applies specifically to the R5F526TFAGNE#10's 100-pin configuration.

What package type and pin count does the R5F526TFAGNE#10 use, and is it RoHS compliant?

The R5F526TFAGNE#10 uses the PLQP0100KB-B package: a 100-pin LQFP measuring 14 × 14 mm with 0.5 mm pitch. It is lead-free and RoHS compliant per Renesas' environmental policy and product change notification PCN-2022-01. This package provides 82 general-purpose I/O pins, including 5-V tolerant and large-current drive variants, optimized for motor control board layouts requiring isolation and thermal management.
