Product details
Overview
R5F524TBAGFP#51 from Renesas Electronics is a 32-bit RXv2 microcontroller optimized for motor control and industrial inverter applications, featuring an 80 MHz CPU core delivering 153.6 DMIPS, on-chip FPU compliant with IEEE754, 256 KB flash memory, 32 KB SRAM, and integrated three-phase complementary PWM generation via MTU3 (2 channels) and GPT (4 channels). It targets real-time motor drive systems requiring precise timing, analog sensing, and CAN communication.
For engineers reviewing the R5F524TBAGFP#51 datasheet, R5F524TBAGFP#51 pinout, R5F524TBAGFP#51 application, or R5F524TBAGFP#51 equivalent, key selection considerations include its 100-pin LFQFP-0.5 mm package, dual 12-bit ADC units with 3-channel simultaneous sampling, programmable gain amplifiers per ADC unit, and dedicated POE3A hardware for safe PWM output enable/disable in fault conditions.
Technical Context
The R5F524TBAGFP#51 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. Its clock system integrates PLL, on-chip oscillators (high/low-speed, IWDT-dedicated), and CAC for real-time clock accuracy monitoring - all configurable via independent ICLK (80 MHz), PCLKA (80 MHz), PCLKB (40 MHz), and ADCLK (40 MHz) domains.
Motor control functionality is anchored by MTU3 (9×16-bit channels) supporting three-phase non-overlapping PWM with automatic dead-time insertion and phase counting, plus GPT (4×16-bit channels) for complementary single-phase or cascaded three-phase PWM. The S12ADF ADC includes sample-and-hold on 3 channels per unit, programmable gain (6-step), and self-diagnostic features aligned with IEC60730 Class B compliance.

FAQ
What is the maximum ADC sampling rate achievable with R5F524TBAGFP#51?
The R5F524TBAGFP#51 supports a minimum conversion time of 1.0 µs per channel when ADCLK runs at 40 MHz. With group scan mode and simultaneous 3-channel sampling on unit 1, it achieves up to 1 MSPS aggregate throughput across those channels - sufficient for 20 kHz FOC current loops with 50 ns timing resolution between samples.
Does R5F524TBAGFP#51 support CAN FD or only classical CAN?
R5F524TBAGFP#51 implements the RSCAN module compliant with ISO11898-1 for classical CAN only (up to 1 Mbps), not CAN FD. It supports standard and extended frames with 16 configurable message boxes but lacks the bit-rate switching and extended data length features of CAN FD.
Can R5F524TBAGFP#51 operate from a 3.3 V supply?
No. R5F524TBAGFP#51 requires a 2.7 V to 5.5 V supply and is specified for 5 V operation (denoted by "A" in the part number suffix). Its I/Os are 5-V tolerant, and internal regulators assume nominal 5 V input; operation below 4.5 V may compromise ADC accuracy and flash programming reliability.
How many independent PWM outputs does R5F524TBAGFP#51 provide?
R5F524TBAGFP#51 provides up to 28 independent PWM output lines: 9 MTU3 channels (each with up to 4 I/O pins) and 4 GPT channels (each with 2 I/O pins), configurable as complementary pairs or single-ended outputs - sufficient for dual 3-phase inverters plus auxiliary control signals.
Is the FPU in R5F524TBAGFP#51 IEEE754-compliant for both single and double precision?
The R5F524TBAGFP#51 includes a single-precision (32-bit) floating-point unit fully compliant with IEEE754. It does not support double-precision operations; all FPU instructions operate on 32-bit operands, matching the RXv2 core's native floating-point instruction set as documented in R01DS0257EJ0200 Rev.2.00.
