Overview
R5F526TBDDFP#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, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM with dead-time control.
For engineers reviewing the R5F526TBDDFP#30 datasheet, R5F526TBDDFP#30 pinout, R5F526TBDDFP#30 application, or R5F526TBDDFP#30 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash architecture enabling background programming, 260 ps high-resolution PWM timing resolution, IEC60730 safety support, and Trusted Secure IP Lite encryption engine.
Technical Context
The R5F526TBDDFP#30 implements the RXv3 CPU core with single-cycle instruction execution, 32×32→64-bit multiplier, 32/32→32-bit divider, and optional single-precision FPU compliant with IEEE 754. It supports little-endian or big-endian data arrangement and includes a memory protection unit (MPU) with eight configurable protection areas down to 16-byte granularity.
Its real-time control subsystem integrates three timer families: 8-channel 32-bit GPTWa for high-precision PWM generation, 9-channel 16-bit MTU3d for 3-phase inverter timing, and 4-channel HRPWM providing 260 ps minimum timing resolution synchronized to GPTW outputs - all clocked from PCLKC up to 120 MHz with independent reference clock domains.
