Product details
Overview
R5F526TFBDFL#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, integrated 512 KB code flash, 64 KB SRAM, 16 KB data flash, and hardware-accelerated 3-phase/5-phase complementary PWM generation. It features CAN FD, dual 12-bit ADC units (22-channel total), 6-channel analog comparator, 2-channel 12-bit DAC, and Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TFBDFL#30 datasheet, R5F526TFBDFL#30 pinout, R5F526TFBDFL#30 application, or R5F526TFBDFL#30 equivalent, this MCU delivers deterministic real-time motor timing via HRPWM (260 ps resolution), IEC60730-compliant safety functions including oscillation-stop detection and RAM self-test, and event-driven peripheral coordination via ELC-critical for high-efficiency PMSM/BLDC drive designs.
Technical Context
The R5F526TFBDFL#30 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 in interrupt-heavy motor control loops. Its clock system supports independent domain scaling: ICLK up to 120 MHz for CPU/core logic, PCLKA up to 120 MHz for MTU3d/GPTWa/HRPWM, and PCLKD up to 60 MHz for S12ADH ADC operation.
Peripheral integration centers on deterministic timing: GPTWa (8-channel, 32-bit) and MTU3d (9-channel, 16-bit) provide synchronized PWM outputs with programmable dead time, phase counting, and A/D trigger alignment; HRPWM refines GPTW0–GPTW3 output edges with 260 ps minimum resolution; ELC enables CPU-free inter-module event chaining (e.g., timer overflow → ADC start → comparator interrupt).
