Product details
Overview
R5F524T8AGFF#31 from Renesas is a 32-bit RXv2 core MCU optimized for motor control and industrial inverter applications, operating at 80 MHz (153.6 DMIPS), featuring integrated FPU (IEEE754 single-precision), 128 KB on-chip flash, 16 KB SRAM, and 8 KB data flash with 1M erase/write cycles. It delivers three-phase complementary PWM ×2 channels + single-phase complementary ×4 channels via MTU3/GPT timers and supports CAN (ISO11898-1) for real-time fieldbus communication.
For engineers reviewing the R5F524T8AGFF#31 datasheet, R5F524T8AGFF#31 pinout, R5F524T8AGFF#31 application, or R5F524T8AGFF#31 equivalent, key selection considerations include its 80-pin LQFP-0.65 mm package, 12-bit ADC with 3-channel synchronous sample-and-hold (unit 1), programmable gain amplifier (3 channels), dual 8-bit DACs for comparator reference, and IEC60730-compliant self-diagnostic features for safety-critical motor drives.
Technical Context
The R5F524T8AGFF#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling deterministic 80-MHz execution and fast interrupt response critical for real-time motor control loops. Its clock system integrates PLL (4–12.5 MHz input), on-chip oscillators (low/high-speed, IWDT-dedicated), and CAC for clock accuracy monitoring - all configurable per peripheral domain (ICLK/PCLKA/PCLKB/PCLKD/FCLK).
Peripheral integration centers on high-resolution timing: MTU3 provides nine 16-bit channels supporting three-phase non-overlapping PWM with automatic dead time, phase counting, and A/D start triggering; GPT adds four 16-bit channels for cascaded 32-bit timing or three-phase + single-phase complementary outputs. The S12ADF ADC includes group-scan priority control, analog disconnection detection, and programmable gain amplification across 22 total channels (5+5+12), with simultaneous sampling capability on unit 1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F524TAADFF#31 | Same 80-pin LQFP package, but 256 KB flash / 16 KB RAM - larger code space for advanced motion profiles and OTA update partitioning. | Preferred for applications requiring embedded web server or dual-bank firmware updates. | Select when firmware size exceeds 128 KB or safety-certified bootloader functionality is required. |
| STM32F303RET6 | ARM Cortex-M4F core, 72 MHz, 512 KB flash, 80-pin LQFP - lacks integrated CAN FD and synchronous 3-channel ADC, but offers higher analog integration density. | Better suited for cost-sensitive consumer appliances where CAN is not mandatory and sensor count is lower. | Choose when leveraging STM32 ecosystem tools and existing HAL libraries outweighs need for Renesas-specific motor control IP. |
Compared with R5F524T8AGFF#31, R5F524TAADFF#31 provides headroom for future firmware expansion while maintaining identical peripheral configuration and pinout; STM32F303RET6 offers broader third-party tool support but requires external components to match R5F524T8AGFF#31's integrated motor control features like automatic dead-time PWM and IEC60730 diagnostics.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F524T8AGFF#31?
The R5F524T8AGFF#31 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance. This is achieved using the RXv2 CPU core with 5-stage pipeline and variable-length instruction set, enabling efficient execution of motor control algorithms such as field-oriented control (FOC) and space-vector modulation in real time. The R5F524T8AGFF#31 maintains this performance across its full operating voltage range (2.7–5.5 V) and temperature range (–40 to +85°C).
Does the R5F524T8AGFF#31 support IEC60730 Class B compliance for safety-critical motor applications?
Yes, the R5F524T8AGFF#31 includes dedicated hardware features for IEC60730 Class B compliance, including self-diagnostic functions for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via the data operation circuit (DOC), and analog input disconnection detection. These capabilities are documented in the R01DS0257EJ0200 datasheet and reduce the software validation burden for safety-certified motor drive designs using the R5F524T8AGFF#31.
What ADC configuration does the R5F524T8AGFF#31 provide for motor current sensing?
The R5F524T8AGFF#31 integrates the S12ADF 12-bit ADC with 22 total channels distributed across three units (5+5+12). Unit 1 includes a 3-channel synchronous sample-and-hold circuit, enabling simultaneous capture of three motor phase currents. Each channel supports programmable sampling time and gain (2.0× to 4.444×), and group-scan priority control ensures deterministic timing for current feedback in vector control loops. This ADC configuration is fully supported on the R5F524T8AGFF#31 in its 80-pin LQFP package.
How many PWM output channels does the R5F524T8AGFF#31 support, and what topologies are available?
The R5F524T8AGFF#31 supports up to nine 16-bit PWM channels via the MTU3 module and four additional channels via the GPT module. MTU3 enables three-phase complementary PWM ×2 channels (for dual inverters) plus single-phase complementary ×4 channels, or alternatively three-phase ×3 + single-phase ×1. All configurations include automatic dead time insertion, phase counting, and A/D trigger synchronization - features critical for high-efficiency motor control implementations using the R5F524T8AGFF#31.
What is the package type and pin count of the R5F524T8AGFF#31, and how does it compare to other RX24T variants?
The R5F524T8AGFF#31 uses an 80-pin LQFP package (PLQP0080JA-A) with 14 × 14 mm body and 0.65 mm pitch. This differs from 100-pin LFQFP (PLQP0100KB-B) and 64-pin LFQFP (PLQP0064KB-C) variants in I/O count and peripheral availability - for example, the 80-pin version omits CAN support present in 100-pin versions but retains full MTU3/GPT PWM, ADC, and SCI/RSPI functionality. The R5F524T8AGFF#31 shares identical pinout with other 80-pin RX24T parts like R5F524TAADFF#31, enabling hardware reuse across memory variants.
