Product details
Overview
R5F526TFBGFN#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and hardware-accelerated 3-phase/5-phase complementary PWM with 260 ps HRPWM resolution.
For engineers reviewing the R5F526TFBGFN#30 datasheet, R5F526TFBGFN#30 pinout, R5F526TFBGFN#30 application, or R5F526TFBGFN#30 equivalent, this MCU targets real-time motor control systems requiring deterministic timing, functional safety support (IEC60730), secure firmware execution (Trusted Secure IP Lite), and simultaneous sampling across three 12-bit A/D units.
Technical Context
The R5F526TFBGFN#30 integrates the RXv3 CPU core with single-precision FPU, memory protection unit (MPU), and Trusted Memory (TM) for secure code execution. Its clock system combines an 8–24 MHz external crystal with PLL to generate 120 MHz ICLK, while PCLKA/PCLKC run at up to 120 MHz for timers and PWM, and PCLKD at 60 MHz for ADC operation.
Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) support synchronous PWM generation, dead-time insertion, and phase-counting; HRPWM achieves 260 ps edge timing resolution; and S12ADH provides simultaneous sampling across three independent 12-bit A/D units with sample-and-hold for current sensing.
