Product details
Overview
R5F526TBCGND#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.
For engineers reviewing the R5F526TBCGND#30 datasheet, R5F526TBCGND#30 pinout, R5F526TBCGND#30 application, or R5F526TBCGND#30 equivalent, key selection considerations include its 100-pin LQFP package, 120 MHz HRPWM timing resolution (260 ps), dual-bank flash for safe firmware updates, IEC60730-compliant safety features, and integrated trigonometric function unit (TFUv2) for real-time motor vector control.
Technical Context
The R5F526TBCGND#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 in motor control interrupt routines. Its clock system supports PLL multiplication of external 8–24 MHz crystals or internal 16/18/20 MHz HOCO to achieve 120 MHz ICLK.
Peripheral timing is segmented across four PCLK domains: PCLKA (up to 120 MHz) drives MTU3d, GPTWa, and CAN FD; PCLKC (up to 120 MHz) clocks HRPWM and timer counter references; PCLKB (up to 60 MHz) serves ADC, SCI, and DTCb; and PCLKD (up to 60 MHz) feeds S12ADH conversion clocks - enabling precise, independent timing for motor control, sensing, and communication subsystems.
