Product details
Overview
R5F526TBDGND#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.
For engineers reviewing the R5F526TBDGND#50 datasheet, R5F526TBDGND#50 pinout, R5F526TBDGND#50 application, or R5F526TBDGND#50 equivalent, this MCU delivers deterministic real-time motor control with IEC60730-compliant safety features, dual-bank flash for seamless firmware updates, and simultaneous sampling across three 12-bit A/D units - critical for field-oriented control (FOC) and sensorless BLDC commutation.
Technical Context
The R5F526TBDGND#50 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting 113 instructions including DSP and single-precision FPU operations compliant with IEEE754. Its memory protection unit (MPU) enforces eight configurable memory regions with read/write/execute permissions, while Trusted Memory (TM) restricts code fetch access to protected flash areas.
Real-time motor control is enabled by tightly coupled peripherals: GPTWa timers (8-channel, 32-bit) synchronized to PCLKC at up to 120 MHz drive complementary PWM outputs with programmable dead time; MTU3d provides 9-channel 16-bit timer resources with phase-counting and cascade support; and ELC links 183 internal event signals without CPU intervention for low-latency waveform triggering and A/D conversion synchronization.

How many A/D converter channels does the R5F526TBDGND#50 support, and what is their configuration?
The R5F526TBDGND#50 supports 22 total 12-bit A/D channels across three independent S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). All units include sample-and-hold circuits, with Units 0 and 1 each providing three dedicated sample-and-hold channels. This configuration allows true simultaneous sampling - a key requirement for field-oriented control implementations using the R5F526TBDGND#50 in industrial drives.
