Product details
Overview
R5F526T9ADFP#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, and integrated high-resolution PWM with 260 ps timing resolution. It supports CAN FD (ISO 11898-1:2015), dual 12-bit A/D converters with simultaneous sampling across three units, and hardware encryption (AES-128/256) for IEC 60730-compliant safety-critical systems.
For engineers reviewing the R5F526T9ADFP#30 datasheet, R5F526T9ADFP#30 pinout, R5F526T9ADFP#30 application, or R5F526T9ADFP#30 equivalent, key selection considerations include its 100-pin LFQFP package with 82 general-purpose I/Os (2× 5-V tolerant), 3-phase/5-phase complementary PWM capability, 120 MHz GPTWa timer operation, and support for real-time motor control loop execution with ELC-triggered peripheral coordination.
Technical Context
The R5F526T9ADFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in interrupt-heavy motor control loops. Its clock system integrates a PLL referenced to an 8–24 MHz crystal, internal HOCO (16/18/20 MHz), and dedicated 120 kHz IWDT oscillator - enabling independent watchdog operation during deep sleep modes.
Peripheral coordination is handled by the Event Link Controller (ELC), which interconnects 183 internal event signals (e.g., MTU3d compare match, GPTWa overflow) to trigger timer starts/stops, ADC conversions, or port output changes without CPU intervention - critical for deterministic timing in field-oriented control (FOC) implementations.
