Product details
Overview
R5F526TFCGFN#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 HRPWM timing resolution.
For engineers reviewing the R5F526TFCGFN#10 datasheet, R5F526TFCGFN#10 pinout, R5F526TFCGFN#10 application, or R5F526TFCGFN#10 equivalent, key selection considerations include its dual-bank flash architecture for safe firmware updates, IEC60730-compliant safety features (oscillation-stop detection, RAM test assist, CRC), and dedicated motor-control peripherals including MTU3d (9-channel 16-bit timer), GPTWa (8-channel 32-bit PWM), and CMPCa (6-channel analog comparator).
Technical Context
The R5F526TFCGFN#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-critical for real-time motor control loop execution. Its clock system supports PLL multiplication of external 8–24 MHz crystals or internal HOCO (16/18/20 MHz) to achieve 120 MHz ICLK, while PCLKA/PCLKC run at up to 120 MHz to synchronize high-speed peripherals like GPTWa and HRPWM.
Motor control is enabled by tightly coupled peripherals: MTU3d provides 3-phase complementary PWM with automatic dead-time insertion and phase-counting mode; GPTWa delivers 10 single-phase, 3 three-phase, or 2 five-phase complementary PWM outputs; and HRPWM adds 260 ps edge placement resolution to GPTW0–GPTW3 outputs. The S12ADH A/D converter supports simultaneous sampling across three units (4+4+14 channels) with programmable gain amplifiers and disconnection detection for sensor health monitoring.
