Product details
Overview
R5F526T9BGFP#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. It operates across –40°C to +105°C and supports IEC60730 safety compliance.
For engineers reviewing the R5F526T9BGFP#10 datasheet, R5F526T9BGFP#10 pinout, R5F526T9BGFP#10 application, or R5F526T9BGFP#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 100-pin LFQFP package with 82 general-purpose I/O pins including 5-V tolerant inputs.
Technical Context
The R5F526T9BGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. Its clock system integrates an 8–24 MHz external crystal oscillator, PLL, and dedicated 120 kHz IWDT oscillator - all supporting independent domain clocking (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Peripheral timing is tightly coordinated: MTU3d and GPTWa timers synchronize to PCLKC (up to 120 MHz) for precise PWM edge placement, while S12ADH A/D conversion runs on ADCLK derived from PCLKD (up to 60 MHz). The ELC enables interrupt-free inter-module triggering - e.g., MTU3d events directly initiating A/D conversions or HRPWM updates without CPU intervention.
