Product details
Overview
R5F526TBADFN#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, 512 KB on-chip flash, 48 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and dual 12-bit D/A converters. It targets real-time closed-loop motor drive systems requiring IEC60730 functional safety compliance.
For engineers reviewing the R5F526TBADFN#10 datasheet, R5F526TBADFN#10 pinout, R5F526TBADFN#10 application, or R5F526TBADFN#10 equivalent, key selection criteria include its 120-MHz GPTWa timer with 3-phase/5-phase complementary PWM support, 12-bit S12ADH A/D converter with simultaneous sampling across two units (7 + 8 channels), 6-channel analog comparator, and Trusted Secure IP Lite encryption engine with AES-128/256.
Technical Context
The R5F526TBADFN#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 in motor control ISR handling. Its clock system integrates PLL-synthesized 120 MHz ICLK, independent IWDT oscillator (120 kHz), and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D up to 60–120 MHz) enabling precise timing separation between control loops and communication stacks.
It features event-driven architecture via ELC (183 internal signals), allowing MTU3d and GPTWa timers to trigger A/D conversion or update PWM duty cycles without CPU intervention-critical for deterministic field-oriented control (FOC) execution. The device includes dedicated hardware acceleration for trigonometric functions (TFUv2) and CRC calculation (CRCA) to offload safety-critical computations.
