Product details
Overview
R5F526TFBGNE#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and power conversion, operating at up to 120 MHz with 709 CoreMark performance, 512 KB on-chip flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and dual-bank flash for safe firmware updates - deployed in industrial inverters and servo drives.
For engineers reviewing the R5F526TFBGNE#10 datasheet, R5F526TFBGNE#10 pinout, R5F526TFBGNE#10 application, or R5F526TFBGNE#10 equivalent, key selection criteria include its 120-MHz GPTWa timer with 3-phase/5-phase complementary PWM, 12-bit S12ADH ADC with simultaneous sampling across three units, Trusted Secure IP Lite encryption, IEC60730 safety support, and PLQP0100KB-B 100-pin QFP package with 5-V-tolerant I/O.
Technical Context
The R5F526TFBGNE#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 real-time motor control loops. It integrates dedicated peripherals including MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) synchronized to PCLKC at up to 120 MHz for precise timing-critical waveform generation.
Its clock system combines an external 8–24 MHz crystal oscillator with PLL multiplication, internal HOCO (16/18/20 MHz), and IWDT-dedicated 120-kHz oscillator - enabling independent clock domains for CPU (ICLK), peripherals (PCLKA–PCLKD), and flash interface (FCLK). The ELC enables hardware-triggered inter-module operation without CPU intervention, critical for deterministic response in field-oriented control (FOC) algorithms.
