Product details
Overview
R5F526TBDDFN#10 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, 48 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 operates across –40°C to +85°C.
For engineers reviewing the R5F526TBDDFN#10 datasheet, R5F526TBDDFN#10 pinout, R5F526TBDDFN#10 application, or R5F526TBDDFN#10 equivalent, key selection criteria include its 16-bit GPTWa timer configuration, 48 KB RAM variant, 64-pin HWQFN package (PWQN0064KF-A), dual-bank flash architecture, and integrated HRPWM/MTU3d for 3-phase inverter gate driving.
Technical Context
The R5F526TBDDFN#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and memory protection unit (MPU) supporting eight configurable regions. Its clock system integrates PLL with external 8–24 MHz crystal support, internal HOCO (16/18/20 MHz), and dedicated 120 kHz IWDT oscillator.
Peripheral coordination is managed via Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts/stops, A/D conversion, or port output changes without CPU intervention. The device uses PCLKA (up to 120 MHz) for MTU3d/GPTWa/HRPWM, PCLKC (up to 120 MHz) as counter reference, and PCLKD (up to 60 MHz) for S12ADH ADC operation.
