Renesas R5F526T9ADFL#30

Overview

R5F526T9ADFL#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, and integrated CAN FD interface. It supports simultaneous sampling across three 12-bit A/D converter units (up to 22 channels), six analog comparators, two 12-bit D/A outputs, and high-resolution PWM with 260 ps timing resolution for precise gate drive control in 3-phase and 5-phase inverters.

For engineers reviewing the R5F526T9ADFL#30 datasheet, R5F526T9ADFL#30 pinout, R5F526T9ADFL#30 application, or R5F526T9ADFL#30 equivalent, key selection considerations include its dual-bank flash architecture enabling background programming, Trusted Secure IP Lite encryption (AES-128/256), IEC60730 safety support (oscillation detection, RAM test assist, CRC), and dedicated HRPWM timing control for field-oriented control (FOC) implementations.

Technical Context

The R5F526T9ADFL#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 register banks for fast context switching, and optional big-endian data handling. Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and selectable 16/18/20 MHz HOCO, plus PLL multiplication up to 120 MHz - with independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains for peripheral timing isolation.

Motor control functionality is anchored by the GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel sub-260 ps resolution), all synchronized to PCLKC and linked via Event Link Controller (ELC) to eliminate CPU intervention during PWM dead-time compensation, A/D trigger generation, and comparator-based fault response - critical for real-time inverter protection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9ADFL#30?

The R5F526T9ADFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 16 register banks, and optimized memory subsystem - making R5F526T9ADFL#30 suitable for real-time motor control loops with sub-microsecond latency requirements.

Does the R5F526T9ADFL#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9ADFL#30 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist via DOC, CRC calculator (CRCA), independent watchdog timer (IWDT) with window function, register write protection, and self-diagnostic A/D functions. These capabilities are integrated into the silicon and documented in Renesas' safety manual R01UM0517EJ0100 - no external components are needed to implement the core safety mechanisms for R5F526T9ADFL#30.

How many analog input channels does the R5F526T9ADFL#30 support, and what is their sampling capability?

The R5F526T9ADFL#30 supports 22 analog input channels across three independent 12-bit S12ADH A/D converter units - unit 0 (4 channels), unit 1 (4 channels), and unit 2 (14 channels). Each channel achieves a minimum conversion time of 0.9 µs at 60 MHz ADCLK, and all units support simultaneous sampling triggered by MTU/GPTW events - enabling accurate current reconstruction in 3-phase motor control using R5F526T9ADFL#30.

What PWM resolution and complementary modes are supported by the R5F526T9ADFL#30?

The R5F526T9ADFL#30 delivers 260 ps minimum timing resolution via its 4-channel HRPWM block, which refines the output of GPTW0–GPTW3. It supports single-phase (10 outputs), 3-phase (3 outputs), and 5-phase (2 outputs) complementary PWM modes with automatic dead-time insertion, phase counting, and synchronous start/stop - all coordinated through the Event Link Controller to minimize CPU overhead in inverter gate drive control using R5F526T9ADFL#30.

Is the R5F526T9ADFL#30 pin-compatible with other RX26T group MCUs?

No, the R5F526T9ADFL#30 uses the 100-pin PLQP0100KB-B package and is not pin-compatible with smaller RX26T variants (e.g., 64-pin or 48-pin packages). Pin assignments for MTU, GPTW, A/D, and CAN FD are specific to this 100-pin configuration. Migration to other RX26T devices requires PCB redesign - though software compatibility is maintained within the RXv3 architecture and Renesas' SSP framework for R5F526T9ADFL#30.
