Product details
Overview
R5F526TFBDND#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and power conversion, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and high-resolution PWM with 260 ps timing resolution. It targets real-time inverter control in industrial drives and HVAC compressors.
For engineers reviewing the R5F526TFBDND#10 datasheet, R5F526TFBDND#10 pinout, R5F526TFBDND#10 application, or R5F526TFBDND#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM support, dual-bank flash for safe firmware updates, IEC60730-compliant safety features (IWDT, oscillation-stop detection, CRC, MPU), and 100-pin LFQFP package with 82 general-purpose I/Os and 5-V tolerant pins.
Technical Context
The R5F526TFBDND#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast interrupt response. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator, enabling precise timing across PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), and PCLKC (up to 120 MHz) domains.
Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both support dead-time insertion and synchronous PWM output; HRPWM (4 channels) overlays sub-nanosecond edge control onto GPTWa outputs; S12ADH (12-bit ADC with 3 sample-and-hold units) enables simultaneous sampling of current/voltage feedback signals.
