Product details
Overview
R5F526T9BDFM#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip flash, 64 KB SRAM, CAN FD interface, and integrated high-resolution PWM with 260 ps timing resolution. It integrates dual-bank flash for safe firmware updates, 16 KB data flash rated for 100,000 erase/write cycles, and hardware encryption (AES-128/256) for IEC 60730-compliant safety-critical systems.
For engineers reviewing the R5F526T9BDFM#30 datasheet, R5F526T9BDFM#30 pinout, R5F526T9BDFM#30 application, or R5F526T9BDFM#30 equivalent, key selection considerations include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit ADC units, and support for real-time event-driven control via ELC without CPU intervention.
Technical Context
The R5F526T9BDFM#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 motor control interrupt routines. Its clock system supports PLL multiplication of external 8–24 MHz crystals or internal HOCO (16/18/20 MHz), delivering synchronized PCLKA/PCLKC up to 120 MHz for GPTW, MTU3d, and HRPWM modules.
It features dedicated motor control peripherals: eight-channel 32-bit GPTWa timers supporting single-/3-/5-phase complementary PWM with programmable dead time, nine-channel 16-bit MTU3d with automatic dead-time compensation, and four-channel HRPWM enabling sub-nanosecond edge placement (260 ps min resolution at 120 MHz). The S12ADH ADC includes three independent sample-and-hold units for simultaneous sampling across 22 channels.
