Product details
Overview
R5F524TAAGFF#11 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 × 2 channels + single-phase complementary PWM × 4 channels via MTU3 and GPT timers, and supports CAN (ISO 11898-1) for real-time fieldbus communication.
For engineers reviewing the R5F524TAAGFF#11 datasheet, R5F524TAAGFF#11 pinout, R5F524TAAGFF#11 application, or R5F524TAAGFF#11 equivalent, this MCU is selected for high-accuracy motor phase timing, IEC60730-compliant safety diagnostics, and simultaneous 3-channel ADC sampling in compact 80-pin LQFP packages with 0.65 mm pitch.
Technical Context
The R5F524TAAGFF#11 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and deterministic interrupt latency. Its clock system integrates PLL (4–12.5 MHz input), on-chip oscillators (low/high-speed + IWDT-dedicated 15 kHz), and independent clock domains (ICLK @ 80 MHz, PCLKA @ 80 MHz for MTU3/GPT, PCLKB @ 40 MHz for peripherals).
Peripheral integration centers on motor control: MTU3 provides 9×16-bit channels with dead-time compensation, automatic complementary PWM, and A/D trigger synchronization; GPT supplies 4×16-bit channels supporting cascaded 32-bit operation and comparator interlocking. The S12ADF ADC includes 3-unit 12-bit conversion (5+5+12 channels), programmable gain amplifiers (1+3 channels), and sample-and-hold on unit 1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F524TBADFP#31 | 100-pin LFQFP, 256 KB flash, 32 KB SRAM, supports CAN + POE3A (GPT pin control), no DAa | Higher pin count enables more analog inputs and isolated gate driver interfaces; lacks external DA outputs | Select when needing >80 GPIO, full POE3A functionality, or additional ADC channels-requires PCB redesign |
| R5F524T8ADFF#31 | 80-pin LQFP, 128 KB flash, 16 KB SRAM, same package/pinout, no CAN module | Cost-optimized variant for non-fieldbus applications; retains MTU3/GPT/ADC but removes RSCAN | Select for standalone motor control where CAN is unnecessary-pin-compatible drop-in with reduced firmware footprint |
Compared with R5F524TAAGFF#11, R5F524TBADFP#31 offers expanded I/O and memory but requires larger board area, while R5F524T8ADFF#11 reduces cost and complexity by omitting CAN yet maintains identical motor control timing precision and safety features in the same 80-pin footprint.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F524TAAGFF#11?
The R5F524TAAGFF#11 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance using the RXv2 CPU core. This benchmark reflects actual instruction throughput under typical compiler-optimized code execution, validated per Renesas R01DS0257EJ0200 Rev.2.00 test methodology. The R5F524TAAGFF#11 achieves this with zero wait states on SRAM and controlled wait states on flash above 32 MHz.
Does the R5F524TAAGFF#11 support simultaneous sampling across multiple ADC channels?
Yes, the R5F524TAAGFF#11 supports true simultaneous sampling on S12ADF unit 1, which includes a 3-channel sample-and-hold circuit. This allows concurrent acquisition of three analog signals-such as motor phase currents-with sub-microsecond timing alignment. The R5F524TAAGFF#11 uses ADSM0/ADSM1 trigger outputs to synchronize this operation with MTU3 PWM edges.
What safety certifications or built-in diagnostics does the R5F524TAAGFF#11 provide for IEC60730 compliance?
The R5F524TAAGFF#11 includes multiple IEC60730 Class B support features: ADC disconnection detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, RAM test assistance via DOC, and register write protection. These are documented in Section 1.1 of R01DS0257EJ0200 and enable self-test routines without external components-reducing certification effort for R5F524TAAGFF#11-based systems.
Is the R5F524TAAGFF#11 pin-compatible with other RX24T variants in the same package?
The R5F524TAAGFF#11 shares the same 80-pin LQFP (PLQP0080JA-A) package and pinout with R5F524T8ADFF#31 and R5F524TAADFF#31, making it a direct replacement within the FF package family. However, R5F524TAAGFF#11 differs in ROM/RAM configuration (256 KB/16 KB) and includes CAN functionality not present in the R5F524T8ADFF#31 variant-requiring firmware validation for CAN-dependent features.
What is the endurance specification for the on-chip data flash memory in the R5F524TAAGFF#11?
The R5F524TAAGFF#11 includes 8 KB of on-chip data flash memory rated for 1,000,000 erase/write cycles (typical value per R01DS0257EJ0200 Rev.2.00). It supports background operation (BGO), allowing program/erase while executing code from main flash-essential for logging operational data in motor control applications without interrupting real-time tasks.
