Product details
Overview
R5F526TFDDFM#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial inverter applications, 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), and dual-bank flash for safe firmware updates - deployed in brushless DC motor drives and servo amplifier systems.
For engineers reviewing the R5F526TFDDFM#10 datasheet, R5F526TFDDFM#10 pinout, R5F526TFDDFM#10 application, or R5F526TFDDFM#10 equivalent, key selection criteria include 120-MHz real-time PWM timing resolution, IEC60730-compliant safety features (IWDT, oscillation-stop detection, CRC, RAM test assist), 3-phase/5-phase complementary PWM support, and Trusted Secure IP Lite encryption for secure boot and firmware integrity.
Technical Context
The R5F526TFDDFM#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 motor control interrupt routines. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent 120-kHz IWDT oscillator, and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKC for HRPWM timing).
Real-time motor control is enabled by tightly coupled peripherals: GPTWa (8-channel 32-bit timer) synchronized with HRPWM for sub-nanosecond edge placement, MTU3d for 3-phase inverter dead-time compensation, ELC for CPU-free event chaining (e.g., A/D trigger → PWM update → comparator response), and S12ADH with simultaneous sampling across three 12-bit units.
