R5F524UBAGFB#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 80 MHz (153.6 DMIPS), featuring on-chip 256 KB flash, 32 KB SRAM, 8 KB data flash, IEEE 754-compliant FPU, and integrated CAN, RSPI, SCI, RIIC, and 12-bit ADC with 3-channel synchronous sample-and-hold. It targets industrial motor control and embedded automation requiring deterministic real-time response and IEC60730 safety support.

For engineers reviewing the R5F524UBAGFB#30 datasheet, R5F524UBAGFB#30 pinout, R5F524UBAGFB#30 application, or R5F524UBAGFB#30 equivalent, key selection considerations include its 144-pin LFQFP package, 80-MHz PWM with three-phase complementary output ×2 channels, 12-bit ADC unit configuration (5+5+12 channels), dual 8-bit DAC outputs, and hardware safety features including MPU, IWDT, CAC, and self-diagnostic A/D assistance.

Technical Context

The R5F524UBAGFB#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. It integrates a dedicated 15-kHz IWDT oscillator, on-chip PLL (4–12.5 MHz input), and clock frequency accuracy measurement circuit (CAC) for real-time clock monitoring.

Its peripheral set includes MTU3 (9×16-bit channels) supporting three-phase complementary PWM with automatic dead-time insertion, GPT (4×16-bit channels) for flexible PWM generation, and S12ADF with per-channel sampling time control, group scan priority, and programmable gain amplifiers (1+3 channels). The device supports simultaneous 3-channel sampling in Unit 1 and double-data-register operation for shunt-based current sensing.

FAQ

What is the maximum operating frequency and core type of the R5F524UBAGFB#30?

The R5F524UBAGFB#30 operates at a maximum frequency of 80 MHz using the 32-bit RXv2 CPU core, delivering 153.6 DMIPS performance. Its Harvard architecture with 5-stage pipeline and variable-length instruction set enables efficient code density and deterministic interrupt latency-critical for hard real-time motor control loops executed within strict timing windows.

Does the R5F524UBAGFB#30 include hardware support for functional safety standards like IEC60730?

Yes, the R5F524UBAGFB#30 integrates multiple hardware features for IEC60730 Class B compliance: memory protection unit (MPU), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, clock frequency accuracy measurement circuit (CAC), data operation circuit (DOC) for RAM testing, and self-diagnostic assistance for the A/D converter and analog input disconnection detection-reducing software validation burden.

How many ADC channels and what resolution does the R5F524UBAGFB#30 support?

The R5F524UBAGFB#30 includes a 12-bit S12ADF ADC distributed across three independent units: Unit 0 (5 channels), Unit 1 (5 channels), and Unit 2 (12 channels), totaling 22 configurable inputs. Unit 1 supports 3-channel synchronous sample-and-hold for simultaneous current sensing, and both Unit 0 and Unit 1 include programmable gain amplifiers (1 and 3 channels respectively) for direct low-level signal conditioning.

What PWM capabilities does the R5F524UBAGFB#30 offer for motor control applications?

The R5F524UBAGFB#30 provides two dedicated three-phase complementary PWM outputs via MTU3 (channels 0 and 9), each with automatic dead-time insertion, adjustable duty cycle (0–100%), and reset-synchronized operation. It also supports single-phase complementary PWM across four GPT channels-enabling full-bridge, half-bridge, and multi-phase inverter topologies with hardware-coordinated timing and fault response.

What package type and pin count does the R5F524UBAGFB#30 use?

The R5F524UBAGFB#30 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package (LFQFP) with 20 mm × 20 mm body size and 0.5 mm pin pitch. This package supports 111 general-purpose I/O pins, including 5-V tolerant inputs and open-drain outputs, and is RoHS-compliant with Sn-only surface finish-optimized for industrial PCB layouts requiring thermal and EMI robustness.
