Renesas R5F524TCAGFP#51

Overview

R5F524TCAGFP#51 from Renesas Electronics is a 32-bit RXv2 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 80 MHz (153.6 DMIPS), featuring integrated FPU (IEEE 754 single-precision), 384 KB on-chip flash, 32 KB SRAM, and dual 12-bit ADC units with 3-channel synchronous sample-and-hold for precise current sensing in three-phase PMSM/BLDC drives.

For engineers reviewing the R5F524TCAGFP#51 datasheet, R5F524TCAGFP#51 pinout, R5F524TCAGFP#51 application, or R5F524TCAGFP#51 equivalent, this MCU delivers deterministic real-time PWM timing (MTU3 + GPT), IEC60730-compliant self-diagnostic support, CAN 2.0B interface, and hardware-assisted dead-time compensation - critical for functional safety–aware motor control designs.

Technical Context

The R5F524TCAGFP#51 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling 1-instruction-per-cycle execution at 80 MHz. Its memory protection unit (MPU) enforces eight configurable regions with read/write/execute access control, while the on-chip CAC circuit continuously validates clock accuracy against external references for IEC60730 Class B compliance.

Motor control execution relies on tightly coupled peripherals: MTU3 provides nine 16-bit channels supporting three-phase complementary PWM ×2 + single-phase complementary ×4 outputs with automatic dead-time insertion, while GPT adds four 16-bit channels capable of cascaded 32-bit operation and comparator-interlocked PWM negation - all synchronized to PCLKA at 80 MHz.

FAQ

What is the maximum operating frequency and core type of the R5F524TCAGFP#51?

The R5F524TCAGFP#51 operates at a maximum frequency of 80 MHz using the 32-bit RXv2 CPU core. This core delivers 153.6 DMIPS performance, supports IEEE 754-compliant single-precision floating-point operations, and features a 5-stage pipeline with variable-length instructions for ultra-compact code density. The R5F524TCAGFP#51 achieves deterministic real-time execution essential for motor control loops.

Does the R5F524TCAGFP#51 include hardware support for IEC60730 compliance?

Yes, the R5F524TCAGFP#51 includes multiple hardware features for IEC60730 Class B compliance: self-diagnostic ADC disconnection detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, memory protection unit (MPU), register write protection, and data operation circuit (DOC) for RAM testing. These capabilities are documented in the R01DS0257EJ0200 datasheet and reduce external component count for safety-certified designs.

How many PWM output channels does the R5F524TCAGFP#51 support, and what types are available?

The R5F524TCAGFP#51 supports up to nine 16-bit MTU3 channels and four 16-bit GPT channels for PWM generation. MTU3 provides three-phase complementary PWM ×2 channels plus single-phase complementary ×4, with automatic dead-time insertion and phase counting. GPT supports three-phase ×1 + single-phase complementary ×1 or single-phase complementary ×4 configurations, with comparator interlock for fault-responsive PWM negation. Both modules operate synchronously at 80 MHz PCLKA.

What ADC resources are integrated into the R5F524TCAGFP#51, and how are they structured?

The R5F524TCAGFP#51 integrates three 12-bit S12ADF ADC units: unit 0 (5 channels), unit 1 (5 channels + 3-channel synchronous sample-and-hold), and unit 2 (12 channels). Unit 1's synchronous S/H enables simultaneous sampling of three-phase motor currents. Each channel supports programmable sampling time, group scan priority, and self-diagnostic functions. Programmable gain amplifiers (1 ch in unit 0, 3 ch in unit 1) provide 2.0×–4.444× gain for shunt-based current sensing - all confirmed in the R5F524TCAGFP#51 datasheet.

Is the R5F524TCAGFP#51 pin-compatible with other members of the RX24T Group?

The R5F524TCAGFP#51 uses a 100-pin LFQFP (PLQP0100KB-B) package and shares identical pinout with other 100-pin RX24T variants like R5F524TEAGFP#51 and R5F524TBAGFP#51. Pin compatibility is confirmed in Table 1.2 of R01DS0257EJ0200, which shows identical peripheral mappings across chip versions B in the 100-pin configuration - enabling drop-in replacement where flash/SRAM requirements align.
