Product details
Overview
R5F526TFAGFN#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/5-phase complementary PWM generation with 260 ps timing resolution.
For engineers reviewing the R5F526TFAGFN#10 datasheet, R5F526TFAGFN#10 pinout, R5F526TFAGFN#10 application, or R5F526TFAGFN#10 equivalent, key selection criteria include its 100-pin HWQFN package (PWQN0064KF-A), dual-bank flash architecture enabling background programming, IEC60730-compliant safety features, and dedicated HRPWM circuitry for high-precision inverter gate drive timing.
Technical Context
The R5F526TFAGFN#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 supports independent PCLKA (up to 120 MHz) and PCLKC (up to 120 MHz) domains, allowing GPTWa timers and HRPWM to operate at full resolution while peripheral modules run at lower frequencies.
Hardware safety mechanisms include MPU-based memory protection, Trusted Memory (TM) for secure boot code isolation, CRC calculator (CRCA) with configurable polynomials, oscillation-stop detection, and register write protection-collectively supporting IEC60730 Class B compliance. The ELC enables event-triggered peripheral coordination without CPU intervention, critical for synchronized PWM, ADC sampling, and fault response.
