Renesas R5F524UCAGFP#10

Overview

R5F524UCAGFP#10 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 80 MHz (153.6 DMIPS), featuring on-chip 384 KB flash, 32 KB SRAM, 8 KB data flash, IEEE 754-compliant FPU, and integrated CAN, RSPI, SCI, RIIC, and 12-bit ADC with 3-channel simultaneous sampling - deployed in industrial motor control and power conversion systems.

For engineers reviewing the R5F524UCAGFP#10 datasheet, R5F524UCAGFP#10 pinout, R5F524UCAGFP#10 application, or R5F524UCAGFP#10 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase complementary PWM support across MTU3 and GPT timers, IEC60730 safety features, 5-V tolerant I/O, and dual 8-bit DAC outputs usable as comparator references.

Technical Context

The R5F524UCAGFP#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling single-cycle execution for most operations and supporting both little- and big-endian data arrangement. It integrates a memory protection unit (MPU) with eight configurable regions and register write protection to enforce runtime memory safety.

Clock management includes a PLL (4–12.5 MHz input), main oscillator (1–20 MHz), and dedicated IWDT oscillator (15 kHz), with independent clock domains for ICLK (80 MHz), PCLKA (80 MHz), PCLKB (40 MHz), PCLKD (40 MHz), and FCLK (32 MHz). Peripheral timing is strictly partitioned: MTU3/GPT/SCI11 run on PCLKA; other peripherals on PCLKB; S12AD on PCLKD.
