Product details
Overview
R5F524TAADFN#30 from Renesas 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, 16 KB SRAM, and 8 KB data flash. It integrates dual 12-bit ADC units (5+5 channels), three-phase complementary PWM via MTU3 (2 channels), CAN interface (ISO11898-1), and IEC60730 safety support.
For engineers reviewing the R5F524TAADFN#30 datasheet, R5F524TAADFN#30 pinout, R5F524TAADFN#30 application, or R5F524TAADFN#30 equivalent, this MCU is selected for real-time motor phase control, embedded power conversion systems requiring deterministic PWM timing, and safety-critical industrial drives needing self-diagnostic A/D and clock accuracy monitoring.
Technical Context
The R5F524TAADFN#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and ultra-compact code density. Its CPU operates at 80 MHz with single-cycle instruction execution, 32-bit × 32-bit multiplier, 32-bit divider (2-cycle min), and integrated 32-bit single-precision FPU.
Peripheral timing is segmented: ICLK = 80 MHz for CPU/core, PCLKA = 80 MHz for MTU3/GPT, PCLKB = 40 MHz for most peripherals, PCLKD = 40 MHz for S12AD, and FCLK = 32 MHz for flash access. The chip supports IEC60730 compliance via built-in MPU, DOC, CAC, IWDT, and A/D disconnection detection.
