Product details
Overview
R5F526TBADND#30 from Renesas is a 32-bit RXv3 core MCU optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, 512 KB on-chip flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min resolution), and dual-bank flash for safe firmware updates.
For engineers reviewing the R5F526TBADND#30 datasheet, R5F526TBADND#30 pinout, R5F526TBADND#30 application, or R5F526TBADND#30 equivalent, key selection criteria include its 3-phase/5-phase complementary PWM capability, IEC60730-compliant safety features, 12-bit simultaneous-sampling ADC with 3 sample-and-hold units, and Trusted Secure IP Lite encryption support for secure firmware deployment.
Technical Context
The R5F526TBADND#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, 240-kHz LOCO, and 16–20-MHz HOCO, enabling independent PCLKA (120 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains for precise peripheral timing.
Motor control is enabled by tightly coupled peripherals: GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), HRPWM (4-channel, 260 ps resolution), and ELC for interrupt-free event chaining between timers, ADC, and PWM - all synchronized to PCLKC for deterministic waveform generation and sampling.
