Product details
Overview
R5F526TFCDFN#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip flash, 64 KB SRAM, CAN FD interface, and 4-channel high-resolution PWM with 260 ps timing resolution. It integrates dual-bank flash for safe firmware updates, 16 KB data flash rated for 100,000 erase/write cycles, and hardware encryption (AES-128/256) for IEC 60730-compliant safety-critical systems.
For engineers reviewing the R5F526TFCDFN#10 datasheet, R5F526TFCDFN#10 pinout, R5F526TFCDFN#10 application, or R5F526TFCDFN#10 equivalent, key selection criteria include its 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit ADC units, integrated HRPWM for precise gate timing, and Trusted Secure IP Lite for secure boot and key management - all in a 100-pin LQFP package.
Technical Context
The R5F526TFCDFN#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16-register bank save for fast context switching in real-time motor control loops. Its clock system supports PLL-synthesized 120 MHz ICLK with independent PCLKA/PCLKC domains enabling concurrent 120 MHz peripheral operation (GPTWa, MTU3d, HRPWM) and 60 MHz ADC timing (ADCLK).
Hardware safety features include oscillation-stop detection, RAM test assistance via DOC, CRC calculator (CRCA) with configurable polynomials, register write protection, and independent watchdog timer (IWDTa) with windowed refresh and dedicated 120 kHz oscillator - all certified for IEC 60730 Class B compliance in appliance and industrial drive applications.
