Product details
Overview
R5F524TBADFP#11 from Renesas is a 32-bit RXv2 microcontroller optimized for motor control and industrial inverter applications, featuring an 80 MHz CPU core delivering 153.6 DMIPS, on-chip FPU compliant with IEEE754, 256 KB code flash, 32 KB SRAM, and integrated three-phase complementary PWM generation via MTU3 (2 channels) and GPT (4 channels).
For engineers reviewing the R5F524TBADFP#11 datasheet, R5F524TBADFP#11 pinout, R5F524TBADFP#11 application, or R5F524TBADFP#11 equivalent, key selection considerations include its 100-pin LFQFP-0.5 mm package, IEC60730-compliant self-diagnostic A/D converter with 3-channel synchronous sample-and-hold, CAN interface (ISO11898-1), and dedicated hardware for dead-time compensation and phase counting in motor drive timing.
Technical Context
The R5F524TBADFP#11 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its clock system integrates PLL (4–12.5 MHz input), on-chip oscillators (high/low-speed + IWDT-dedicated), and CAC for real-time clock accuracy monitoring.
Motor control functionality is anchored in dual timer subsystems: MTU3 supports 9 channels at 80 MHz with three-phase complementary PWM × 2, automatic dead-time insertion, and A/D start triggering; GPT provides 4 channels supporting single-phase complementary × 4 or three-phase × 1 + single-phase × 1, with comparator interlocking and synchronized counter operation.

The R5F524TBADFP#11 operates at a maximum frequency of 80 MHz using the RXv2 CPU core, achieving 153.6 DMIPS. Its 5-stage pipeline, variable-length instruction set, and on-chip 2 KB ROM cache (disabled by default) enable deterministic real-time execution critical for motor control loops. The R5F524TBADFP#11 maintains zero wait-state access to SRAM at 80 MHz, ensuring consistent timing for interrupt-driven PWM updates and A/D sampling.
Does the R5F524TBADFP#11 support IEC60730 functional safety compliance?
Yes, the R5F524TBADFP#11 includes multiple hardware features for IEC60730 Class B compliance: self-diagnostic A/D converter with analog disconnection detection, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance via DOC, and memory protection unit (MPU). These capabilities are documented in the R01DS0257EJ0200 datasheet and enable certified safety firmware implementation without external components. The R5F524TBADFP#11 is explicitly targeted for safety-critical motor control applications.
What PWM configurations does the R5F524TBADFP#11 support for three-phase inverter control?
The R5F524TBADFP#11 supports three-phase inverter control via two dedicated timer units: MTU3 provides three-phase complementary PWM × 2 channels with automatic dead-time insertion, phase counting mode, and A/D start triggering; GPT offers three-phase × 1 + single-phase complementary × 1 or single-phase complementary × 4. Both units operate at 80 MHz and support comparator interlocking for fault shutdown. This configuration allows full-bridge driving of dual motors or redundant control paths. The R5F524TBADFP#11's POE3A module enables hardware-controlled high-impedance state for safe gate driver disable during faults.
How many A/D channels and what sampling capabilities does the R5F524TBADFP#11 provide?
The R5F524TBADFP#11 integrates a 12-bit S12ADF A/D converter with 22 total channels distributed across three units: unit 0 (5 channels), unit 1 (5 channels), and unit 2 (12 channels). Unit 1 includes a 3-channel synchronous sample-and-hold circuit enabling simultaneous sampling-essential for accurate three-phase current reconstruction in FOC. Each channel supports programmable sampling time, group scan priority control (3 levels), and self-diagnostic functions. The R5F524TBADFP#11 also features a programmable gain amplifier (1 channel in unit 0, 3 in unit 1) with six selectable gains for direct shunt-resistor interfacing.
What communication interfaces are integrated into the R5F524TBADFP#11?
The R5F524TBADFP#11 integrates CAN (1 channel, ISO11898-1 compliant), 3× SCI (supporting asynchronous, clock-synchronous, smart card, simplified SPI/I²C modes), 1× RIIC (I²C/SMBus up to 400 kbps), and 1× RSPI (SPI up to 20 Mbps). All interfaces support LSB/MSB-first transfer and configurable bit widths (8–32 bits). The CAN module includes 16 message boxes and supports both standard and extended frames. These interfaces enable robust connectivity in motor drive systems-from fieldbus networking (CAN) to sensor interfacing (I²C) and high-speed debug/data logging (RSPI). The R5F524TBADFP#11's SCIg units also generate baud rate clocks from TMR timers for precise timing.
