Product details
Overview
R5F526TBADNE#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 with dead-time control. It supports IEC60730 Class B safety compliance and operates across –40°C to +85°C.
For engineers reviewing the R5F526TBADNE#30 datasheet, R5F526TBADNE#30 pinout, R5F526TBADNE#30 application, or R5F526TBADNE#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 83-pin PLQP0100KB-B (14 × 14 mm) QFP package.
Technical Context
The R5F526TBADNE#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 real-time motor control loops. 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 at derived frequencies).
Peripheral timing is tightly coordinated: MTU3d and GPTWa timers synchronize to PCLKC for high-resolution PWM generation, while S12ADH A/D converters operate on PCLKD (up to 60 MHz) with 0.9 µs minimum conversion time. Event Link Controller (ELC) enables direct hardware interconnection between modules-e.g., MTU3d trigger → A/D start-without CPU intervention during sleep mode.
