Renesas R5F524TAADFF#30

Overview

R5F524TAADFF#30 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), 256 KB on-chip flash, 16 KB SRAM, and 8 KB data flash with 1M erase/write cycles. It delivers three-phase complementary PWM output via MTU3 (2 channels) and GPT (4 channels), supports CAN 2.0B (ISO 11898-1), and includes dual 12-bit ADC units with 3-channel simultaneous sampling for shunt-based current sensing.

For engineers reviewing the R5F524TAADFF#30 datasheet, R5F524TAADFF#30 pinout, R5F524TAADFF#30 application, or R5F524TAADFF#30 equivalent, key selection considerations include its 80-pin LQFP package (PLQP0080JA-A, 0.65 mm pitch), IEC60730-compliant safety features (self-diagnostic ADC, CAC, IWDT), and dedicated motor control peripherals including POE3A for waveform output pin control and programmable gain amplifiers for analog signal conditioning.

Technical Context

The R5F524TAADFF#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and deterministic real-time execution. Its clock system integrates PLL (4–12.5 MHz input), on-chip high/low-speed oscillators, and independent IWDT oscillator (15 kHz), with configurable peripheral clocks: PCLKA at 80 MHz for MTU3/GPT, PCLKB at 40 MHz for most peripherals, and ADCLK at 40 MHz for S12ADF.

Motor control capability is anchored by two independent timer subsystems: MTU3 (9×16-bit channels) supporting three-phase non-overlapping PWM with automatic dead time insertion and phase counting, and GPT (4×16-bit channels) enabling cascaded 32-bit operation and comparator-interlocked PWM negation. The device includes 4-channel comparator C with external reference support and dual 8-bit DACs (DAa) for flexible reference voltage generation.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F524TAADFF#30?

The R5F524TAADFF#30 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, variable-length instruction set, and on-chip 32-bit multiplier/divider. The R5F524TAADFF#30 sustains this performance across its full temperature range (–40°C to +85°C) with no wait states on SRAM access and optimized flash wait-state configuration.

Does the R5F524TAADFF#30 support CAN communication, and what version is implemented?

Yes, the R5F524TAADFF#30 integrates a single-channel CAN module (RSCAN) compliant with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) frame formats. It includes 16 configurable message boxes with acceptance filtering and loopback self-test mode. The R5F524TAADFF#30's CAN peripheral operates independently of the main CPU clock, ensuring deterministic timing for real-time industrial networking.

How many ADC channels does the R5F524TAADFF#30 support, and what is its simultaneous sampling capability?

The R5F524TAADFF#30 integrates three 12-bit S12ADF units: Unit 0 (5 channels), Unit 1 (5 channels + 3-channel simultaneous sample-and-hold), and Unit 2 (12 channels). Unit 1's 3-channel synchronous S/H enables true simultaneous sampling-critical for accurate three-phase current reconstruction in motor control. Each channel supports programmable sampling time and group scan priority control, and the R5F524TAADFF#30 provides ADC start triggers from MTU3, GPT, or TMR timers.

What safety features does the R5F524TAADFF#30 include for IEC60730 compliance?

The R5F524TAADFF#30 includes multiple hardware-assisted IEC60730 Class B features: Clock Frequency Accuracy Measurement Circuit (CAC) for oscillator monitoring, Independent Watchdog Timer (IWDT) with dedicated 15-kHz oscillator, RAM test assistance via Data Operation Circuit (DOC), and ADC self-diagnostic/disconnection detection. These features are implemented in silicon and require minimal firmware overhead-enabling R5F524TAADFF#30-based designs to achieve certification without external safety monitors.

What is the package type and pin pitch of the R5F524TAADFF#30?

The R5F524TAADFF#30 is housed in an 80-pin LQFP package designated PLQP0080JA-A, measuring 14 × 14 mm with 0.65 mm pin pitch. It uses lead-free (Sn-only) surface finish and complies with RoHS directives. This package variant supports all core motor control peripherals-including full MTU3, GPT, CAN, and dual 12-bit ADC units-while maintaining compatibility with standard 0.65 mm pitch PCB assembly processes.
