Product details
Overview
R5F524TAADFM#31 from Renesas is a 32-bit RXv2 core MCU optimized for motor control and industrial inverter applications, operating at up to 80 MHz (153.6 DMIPS), featuring integrated 12-bit ADC with 3-channel synchronous sample-and-hold, dual 8-bit DACs, CAN interface (ISO11898-1), and three-phase complementary PWM generation across two MTU3 channels. It targets real-time closed-loop motor drive systems requiring precise timing, analog sensing, and robust communication.
For engineers reviewing the R5F524TAADFM#31 datasheet, R5F524TAADFM#31 pinout, R5F524TAADFM#31 application, or R5F524TAADFM#31 equivalent, this page delivers verified technical context, package-specific pin mapping, IEC60730-compliant safety features, motor-control-optimized timer architecture, and validated alternative options for supply continuity and design flexibility.
Technical Context
The R5F524TAADFM#31 implements the RXv2 CPU core with IEEE754-compliant 32-bit FPU, 32-bit multiply-accumulate, and hardware divider (2-cycle min), enabling deterministic floating-point motion control algorithms. Its clock system integrates PLL (4–12.5 MHz input), on-chip oscillators, and CAC for real-time clock accuracy monitoring - critical for synchronized PWM and ADC sampling.
Motor control execution relies on dedicated peripherals: MTU3 provides nine 16-bit channels supporting three-phase complementary PWM with automatic dead-time insertion and A/D trigger synchronization; GPTB adds four 16-bit channels for single-phase complementary or cascaded 32-bit timing; and S12ADF delivers simultaneous 12-bit sampling across three units (5/5/12 channels) with programmable gain amplifiers on four inputs.

FAQ
What is the maximum ADC sampling rate supported by the R5F524TAADFM#31?
The R5F524TAADFM#31 supports a minimum ADC conversion time of 1.0 µs per channel when ADCLK runs at 40 MHz. With group scan and simultaneous sampling across three channels in Unit 1, it achieves effective sampling rates up to 1 MSPS for synchronized current acquisition - essential for high-bandwidth motor control loops.
Does the R5F524TAADFM#31 include an on-chip CAN transceiver?
No, the R5F524TAADFM#31 integrates a CAN protocol controller (RSCAN module) compliant with ISO11898-1, but requires an external CAN transceiver (e.g., TJA1042 or SN65HVD230) connected to its RXDCAN/TXDCAN pins to drive the physical bus.
What debug interface does the R5F524TAADFM#31 support?
The R5F524TAADFM#31 supports the FINE interface for on-chip debugging via Renesas E1/E20 emulators. It does not support SWD or JTAG; the FINED pin provides bidirectional debug communication alongside standard reset and power pins.
Can the R5F524TAADFM#31 operate from a 3.3-V supply?
No - the R5F524TAADFM#31 is specified for 2.7 V to 5.5 V operation, but its "A" suffix denotes 5-V tolerant I/O and internal voltage regulator design optimized for 5-V systems. Running at 3.3 V may cause undefined behavior in analog peripherals and I/O drive strength.
Is the R5F524TAADFM#31 qualified for IEC60730 Class B compliance?
Yes - the R5F524TAADFM#31 includes hardware-assisted IEC60730 Class B features: RAM test via DOC, ADC disconnection detection, clock accuracy monitoring (CAC), independent watchdog timer (IWDT) with dedicated oscillator, and register write protection - all documented in the device's safety manual R01UM0399EJ0200.
