Renesas R5F524UEAGFB#30

Overview

R5F524UEAGFB#30 from Renesas is a 32-bit RXv2 microcontroller with 512 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 80 MHz (153.6 DMIPS) with integrated FPU, 12-bit ADC (22 channels across 3 units), CAN interface (ISO11898-1), and three-phase complementary PWM for motor control. It targets industrial inverter systems requiring IEC60730-compliant safety functions.

For engineers reviewing the R5F524UEAGFB#30 datasheet, R5F524UEAGFB#30 pinout, R5F524UEAGFB#30 application, or R5F524UEAGFB#30 equivalent, key selection criteria include its 144-pin LFQFP package, 80-MHz real-time PWM timing, dual simultaneous sampling ADC capability, integrated CAC for clock accuracy monitoring, and hardware-assisted self-diagnostic features for functional safety certification.

Technical Context

The R5F524UEAGFB#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle instruction execution at 80 MHz. Its memory protection unit (MPU) supports eight configurable regions with 16-byte granularity for secure firmware partitioning.

It integrates MTU3 (9-channel 16-bit timer) and GPT (4-channel 16-bit PWM timer) with hardware dead-time insertion, phase counting, and synchronous counter cascading-enabling precise three-phase motor drive waveforms. The S12ADF ADC includes 3-channel simultaneous sample-and-hold per unit, programmable gain amplifiers (11-step scaling), and analog disconnection detection aligned with IEC60730 Class B requirements.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F524UEAGFB#30?

The R5F524UEAGFB#30 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance. This is achieved through the RXv2 CPU core's 5-stage pipeline and single-cycle instruction execution. The R5F524UEAGFB#30 uses this performance headroom for real-time motor control loops, safety diagnostics, and communication stack processing without external acceleration.

Does the R5F524UEAGFB#30 support simultaneous sampling across multiple ADC channels?

Yes, the R5F524UEAGFB#30 supports simultaneous sampling on up to three channels per ADC unit (S12ADF Unit 1). This is implemented via dedicated 3-channel sample-and-hold circuits, enabling accurate phase-current acquisition in 3-phase motor control. The R5F524UEAGFB#30 also provides ADSM0/ADSM1 trigger outputs to synchronize sampling across all three ADC units.

What safety features does the R5F524UEAGFB#30 include for IEC60730 compliance?

The R5F524UEAGFB#30 includes hardware-assisted IEC60730 Class B features: clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance via DOC, ADC self-diagnostic and analog disconnection detection, and register write protection. These features are documented in the R01DS0278EJ0100 datasheet and reduce external component count for safety certification of the R5F524UEAGFB#30-based system.

What is the package type and pin count of the R5F524UEAGFB#30?

The R5F524UEAGFB#30 uses a 144-pin LFQFP package (PLQP0144KA-B), measuring 20 × 20 mm with 0.5 mm pitch. It provides 111 general-purpose I/O pins, including 90 open-drain outputs and 2 5-V tolerant inputs. This package supports full peripheral access-including CAN, all 6 SCI channels, and dual simultaneous ADC sampling-unlike the 100-pin variant.

Can the R5F524UEAGFB#30 perform three-phase complementary PWM generation?

Yes, the R5F524UEAGFB#30 supports three-phase complementary PWM via its MTU3 unit (2 channels) and GPT unit (1 channel + 1 single-phase channel). Each MTU3 channel provides automatic dead-time insertion, adjustable duty cycle (0–100%), and reset-synchronized waveform generation. This capability is essential for driving 6-switch inverter bridges in motor control applications using the R5F524UEAGFB#30.
