Product details
Overview
R5F524TCADFP#11 from Renesas is a 32-bit RXv2 core MCU optimized for motor control and industrial inverter applications, operating at up to 80 MHz (153.6 DMIPS), featuring on-chip FPU (IEEE 754 single-precision), 384 KB flash, 32 KB SRAM, and integrated 12-bit ADC with 3-channel synchronous sample-and-hold for shunt-based current sensing.
For engineers reviewing the R5F524TCADFP#11 datasheet, R5F524TCADFP#11 pinout, R5F524TCADFP#11 application, or R5F524TCADFP#11 equivalent, key selection considerations include its MTU3-based three-phase complementary PWM (×2 channels), GPT-based single-phase complementary PWM (×4 channels), CAN interface (ISO 11898-1), IEC60730 safety support, and 100-pin LFQFP-0.5 mm package with 5-V tolerant I/O.
Technical Context
The R5F524TCADFP#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 15 kHz), and CAC for real-time clock accuracy monitoring.
Peripheral integration centers on motor control: MTU3 provides nine 16-bit timer channels supporting phase counting, dead-time compensation, and reset-synchronized PWM; GPT delivers four 16-bit channels with cascading, comparator interlocking, and triangle-wave generation; S12ADF includes three independent 12-bit ADC units (5+5+12 channels) with programmable gain amplifiers and self-diagnostic functions compliant with IEC60730 Class B.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F524TCADFP#11?
The R5F524TCADFP#11 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance using the RXv2 CPU core. This benchmark reflects real-world instruction throughput under typical motor control workloads, validated per EEMBC methodology. The R5F524TCADFP#11 achieves this with zero wait-state access to SRAM at 80 MHz and optimized pipeline execution.
Does the R5F524TCADFP#11 support simultaneous sampling across multiple ADC channels?
Yes, the R5F524TCADFP#11 supports true simultaneous sampling on S12ADF unit 1, which includes a 3-channel synchronous sample-and-hold circuit. This capability is essential for accurate current vector measurement in three-phase motor control. The R5F524TCADFP#11 also supports group scan priority control across its 22 total ADC channels (5+5+12), with configurable sampling time per channel.
What motor control-specific peripherals are integrated into the R5F524TCADFP#11?
The R5F524TCADFP#11 integrates MTU3 (9-channel 16-bit timer) for three-phase complementary PWM with hardware dead-time compensation, GPT (4-channel 16-bit timer) for auxiliary PWM and position capture, and S12ADF with programmable gain amplifiers for shunt-based current sensing. These peripherals operate with tight hardware synchronization - e.g., MTU3 can trigger ADC conversion directly - minimizing CPU overhead in real-time motor loops.
Is the R5F524TCADFP#11 certified for IEC60730 Class B compliance?
The R5F524TCADFP#11 includes hardware and firmware-assisted features required for IEC60730 Class B self-test: ADC disconnection detection, RAM test via DOC, clock accuracy monitoring (CAC), and independent watchdog timer (IWDT) with dedicated oscillator. While the MCU itself is not pre-certified, Renesas provides documentation and libraries to help developers achieve Class B compliance - a capability confirmed in the R01DS0257EJ0200 datasheet for the RX24T Group.
What package type and pin count does the R5F524TCADFP#11 use?
The R5F524TCADFP#11 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package (LFQFP) with 14 mm × 14 mm body size and 0.5 mm pin pitch. It features 5-V tolerant I/O, open-drain capability on 60 pins, and pull-up resistors on 80 pins - matching the mechanical and electrical footprint of other RX24T 100-pin variants like R5F524TEADFP#31.
