Product details
Overview
R5F526TFBDFL#10 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 PWM generation with dead-time control - deployed in industrial HVAC compressors and servo drive systems.
For engineers reviewing the R5F526TFBDFL#10 datasheet, R5F526TFBDFL#10 pinout, R5F526TFBDFL#10 application, or R5F526TFBDFL#10 equivalent, key selection considerations include its 100-pin LFQFP package, 120 MHz GPTWa/MTU3d timer subsystem for synchronized 3-phase inverter control, 12-bit S12ADH ADC with simultaneous sampling across three units, HRPWM with 260 ps timing resolution, and Trusted Secure IP Lite for AES-128/256 encryption and IEC60730 Class B compliance support.
Technical Context
The R5F526TFBDFL#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 - enabling deterministic real-time motor control loops. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator, with independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains to decouple high-speed peripherals like GPTWa and MTU3d from lower-speed interfaces.
Hardware safety features include MPU with eight configurable protection areas, Trusted Memory (TM) for secure boot code isolation, CRCA for CRC-32/8 calculation, oscillation-stop detection, and register write protection - all supporting IEC60730 Class B functional safety certification. The ELC enables event-driven inter-module coordination without CPU intervention, allowing low-power sleep-mode operation while maintaining precise PWM–ADC synchronization.
