Product details
Overview
R5F526TFBGFM#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM generation with dead-time control - deployed in HVAC compressors, servo drives, and BLDC motor controllers.
For engineers reviewing the R5F526TFBGFM#30 datasheet, R5F526TFBGFM#30 pinout, R5F526TFBGFM#30 application, or R5F526TFBGFM#30 equivalent, key selection criteria include its 120 MHz real-time PWM timing resolution (260 ps minimum), dual-bank flash for safe firmware updates, IEC60730-compliant self-test features, and support for simultaneous sampling across three 12-bit A/D units - critical for high-fidelity current/voltage sensing in closed-loop motor control.
Technical Context
The R5F526TFBGFM#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and 113 instructions including DSP extensions. Its memory protection unit (MPU) enforces eight configurable protection regions, while Trusted Memory (TM) restricts code fetch access to designated flash areas.
Timing subsystems include PLL-synchronized 120 MHz ICLK, PCLKA/PCLKC at up to 120 MHz for GPTW/HRPWM/MTU3d, and dedicated 120 kHz IWDT oscillator. The ELC enables direct inter-module event chaining without CPU intervention - e.g., MTU3d PWM edge triggers initiating A/D conversion start or comparator output toggling GPTW output enable.
