Product details
Overview
R5F526TFBGFM#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and power conversion, featuring 120 MHz operation, 512 KB on-chip flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, dual 12-bit ADC units with simultaneous sampling, six analog comparators, two 12-bit DACs, and hardware-accelerated trigonometric functions (TFUv2) - deployed in industrial inverters and servo drives.
For engineers reviewing the R5F526TFBGFM#10 datasheet, R5F526TFBGFM#10 pinout, R5F526TFBGFM#10 application, or R5F526TFBGFM#10 equivalent, key selection criteria include 120 MHz PWM timing resolution (260 ps), IEC60730 safety support, Trusted Secure IP Lite encryption, 5-V-tolerant I/O, and dual-bank flash for safe firmware updates in real-time motor control systems.
Technical Context
The R5F526TFBGFM#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching in interrupt-heavy motor control loops. It integrates dedicated peripherals including GPTWa (8-channel 32-bit PWM), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel high-resolution PWM) synchronized to PCLKC at up to 120 MHz.
Its clock system combines an 8–24 MHz external crystal oscillator with PLL multiplication, internal HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling precise timing isolation between control loops, safety monitors, and communication stacks. The ELC enables event-driven peripheral chaining without CPU intervention, critical for deterministic response in field-oriented control (FOC).
