Renesas R5F524T8ADFN#30

Overview

R5F524T8ADFN#30 from Renesas 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 on-chip FPU (IEEE754 single-precision), 128 KB code flash, 16 KB SRAM, 8 KB data flash, and integrated three-phase complementary PWM generation via MTU3 and GPT timers.

For engineers reviewing the R5F524T8ADFN#30 datasheet, R5F524T8ADFN#30 pinout, R5F524T8ADFN#30 application, or R5F524T8ADFN#30 equivalent, this device delivers deterministic real-time motor control with simultaneous 3-channel ADC sampling, programmable gain amplifiers, CAN interface compliance with ISO11898-1, and IEC60730 self-diagnostic support for safety-critical systems.

Technical Context

The R5F524T8ADFN#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling ultra-compact code and fast interrupt response. It integrates dual-clock domain timing: ICLK at 80 MHz for CPU/core peripherals, PCLKA at 80 MHz for MTU3/GPT, and PCLKB/PCLKD at 40 MHz for other peripherals and ADC.

Its motor control subsystem combines MTU3 (9×16-bit channels) and GPT (4×16-bit channels) with hardware dead-time insertion, phase counting, and synchronous PWM output-supporting two independent three-phase complementary outputs or three-phase + single-phase configurations. The S12ADF ADC includes three units (5/5/12 channels), 3-channel simultaneous sample-and-hold, and programmable gain amplifiers on 4 inputs.

FAQ

What is the maximum operating frequency and core type of the R5F524T8ADFN#30?

The R5F524T8ADFN#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, variable-length instruction set, and on-chip FPU enable efficient execution of motor control algorithms and floating-point computations required for field-oriented control.

Does the R5F524T8ADFN#30 include a CAN interface?

No, the R5F524T8ADFN#30 does not include the CAN module (RSCAN). Per Table 1.2 in the datasheet, CAN is only supported in Chip Version B packages (e.g., R5F524TEADFP#31) and is explicitly omitted in the R5F524T8ADFN#30's feature set. This variant prioritizes PWM and ADC resources for cost-optimized inverter applications without CAN bus requirements.

How many ADC channels and what sampling capability does the R5F524T8ADFN#30 support?

The R5F524T8ADFN#30 integrates the S12ADF 12-bit ADC with 22 total channels distributed across three units (5/5/12), and supports true simultaneous sampling on 3 channels within unit 1 using its built-in sample-and-hold circuit-critical for three-shunt current sensing in FOC motor control applications.

What safety certifications or features does the R5F524T8ADFN#30 support for industrial applications?

The R5F524T8ADFN#30 includes multiple IEC60730 Class B compliance assist features: ADC input disconnection detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, memory protection unit (MPU), data operation circuit (DOC) for RAM testing, and CRC calculator-enabling robust self-diagnostic capability without external components.

What is the package type and pin count of the R5F524T8ADFN#30?

The R5F524T8ADFN#30 uses the PLQP0080KB-B package: an 80-pin low-profile quad flat package (LFQFP) with 14 × 14 mm body size and 0.5 mm pin pitch. It operates across the industrial temperature range of –40°C to +85°C and supports 5-V tolerant I/Os on designated pins.
