Overview
R5F526TBAGFP#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, featuring a 120 MHz CPU core, 512 KB on-chip flash memory, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and targets inverter-driven industrial motors and servo systems.
For engineers reviewing the R5F526TBAGFP#10 datasheet, R5F526TBAGFP#10 pinout, R5F526TBAGFP#10 application, or R5F526TBAGFP#10 equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options - all grounded in Renesas' official RX26T Group documentation (R01DS0407EJ0120 Rev.1.20).
Technical Context
The R5F526TBAGFP#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. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent 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 3-phase complementary PWM with automatic dead-time insertion; HRPWM adds 260 ps edge placement resolution to GPTW0–GPTW3 outputs; S12ADH provides simultaneous sampling across three 12-bit A/D units (4+4+14 channels); and CMPCa offers six analog comparators for overcurrent detection.
