Product details
Overview
R5F526T9BGFP#30 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 complementary PWM generation with dead-time control - deployed in HVAC compressors, servo drives, and BLDC motor controllers.
For engineers reviewing the R5F526T9BGFP#30 datasheet, R5F526T9BGFP#30 pinout, R5F526T9BGFP#30 application, or R5F526T9BGFP#30 equivalent, key selection criteria include its 120 MHz real-time PWM timing resolution (260 ps min), dual-bank flash for safe firmware updates, IEC60730-compliant safety features (IWDT, oscillation-stop detection, RAM test assist), and 100-pin LFQFP package with 82 general-purpose I/O pins including 5-V tolerant inputs and large-current outputs.
Technical Context
The R5F526T9BGFP#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 - enabling deterministic motor control loop execution at ≤1 µs latency. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent 120-kHz IWDT oscillator, and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at 60–120 MHz) to decouple high-speed PWM and ADC timing from CPU load.
Real-time peripheral coordination is achieved via the Event Link Controller (ELC), which interconnects 183 internal event signals - allowing MTU3d timers, GPTWa PWM units, S12ADH ADCs, and CMPCa comparators to trigger each other without CPU intervention, critical for synchronized current sampling, gate drive timing, and fault response in inverter systems.

It supports automatic dead-time insertion, non-overlapping output generation, and hardware fault response (via POE inputs) that forces outputs to high-impedance within nanoseconds - all essential for reliable SiC/GaN inverter operation. This capability is intrinsic to the R5F526T9BGFP#30 silicon and requires no external logic.
How many ADC channels and what sampling architecture does the R5F526T9BGFP#30 support?
