Product details
Overview
R5F526TBBGFP#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and high-resolution PWM with 260 ps timing resolution. It delivers 709 CoreMark performance and supports IEC60730 safety compliance in industrial motor drives.
For engineers reviewing the R5F526TBBGFP#30 datasheet, R5F526TBBGFP#30 pinout, R5F526TBBGFP#30 application, or R5F526TBBGFP#30 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, 3-phase/5-phase complementary PWM capability, hardware-accelerated trigonometric functions (TFUv2), and Trusted Secure IP Lite encryption engine.
Technical Context
The R5F526TBBGFP#30 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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling precise timing control across PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains.
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 provides 260 ps resolution on GPTW0–GPTW3 outputs; S12ADH includes three 12-bit A/D units (4+4+14 channels) with simultaneous sampling and programmable gain amplifiers for current/voltage sensing.
