Renesas R5F526TFAGFM#30

Overview

R5F526TFAGFM#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, integrated CAN FD interface, and high-resolution PWM with 260 ps timing resolution.

For engineers reviewing the R5F526TFAGFM#30 datasheet, R5F526TFAGFM#30 pinout, R5F526TFAGFM#30 application, or R5F526TFAGFM#30 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit A/D units, 3-phase/5-phase complementary PWM support, and IEC60730-compliant safety features for certified motor drives.

Technical Context

The R5F526TFAGFM#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and hardware floating-point unit compliant with IEEE 754 single-precision standard. It integrates an event-link controller (ELC) enabling interrupt-free inter-module coordination - critical for deterministic motor control timing.

Its clock system combines an 8–24 MHz external crystal oscillator with PLL synthesis to generate 120 MHz ICLK, while independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains allow precise peripheral clock scaling - essential for synchronizing GPTWa timers, S12ADH converters, and HRPWM outputs without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFAGFM#30?

The R5F526TFAGFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables real-time execution of field-oriented control (FOC) algorithms with sub-microsecond loop times. The RXv3 CPU core supports single-cycle instruction execution and includes hardware floating-point and DSP instructions - all verified in the official R01DS0407EJ0120 datasheet. The R5F526TFAGFM#30 sustains this performance with no wait states across its 512 KB flash and 64 KB SRAM.

Does the R5F526TFAGFM#30 support simultaneous sampling across multiple A/D converter units?

Yes, the R5F526TFAGFM#30 supports true simultaneous sampling using three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each unit has dedicated sample-and-hold circuitry, allowing concurrent acquisition of motor phase currents and DC bus voltage without timing skew. This capability is explicitly confirmed in Table 1.1 and Section 1.1 of the R01DS0407EJ0120 datasheet and is essential for accurate vector control calculations in the R5F526TFAGFM#30.

What PWM resolution and complementary output capabilities does the R5F526TFAGFM#30 provide?

The R5F526TFAGFM#30 delivers 260 ps minimum timing resolution via its 4-channel High-Resolution PWM (HRPWM) module, which enhances GPTWa outputs for precise dead-time control. It supports 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM modes - all with automatic dead-time insertion and non-overlapping waveform generation. These features are documented in the "High-resolution PWM waveform generation circuit (HRPWM)" section and Table 1.1 of the R01DS0407EJ0120 datasheet for the R5F526TFAGFM#30.

Is the R5F526TFAGFM#30 qualified for IEC60730 Class B safety compliance?

Yes, the R5F526TFAGFM#30 includes dedicated hardware features 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 are explicitly listed under "Useful functions for IEC60730 compliance" in the R01DS0407EJ0120 datasheet and are integral to the R5F526TFAGFM#30's safety architecture - not optional add-ons.

What package type and pin count does the R5F526TFAGFM#30 use?

The R5F526TFAGFM#30 uses a 100-pin Low-Profile Quad Flat Package (LFQFP) with PLQP0100KB-B footprint: 14 × 14 mm body size, 0.5 mm pin pitch. It provides 82 general-purpose I/O pins, including 2× 5-V tolerant inputs and 15× large-current outputs. This package information is confirmed in the "Package Information" section of the R01DS0407EJ0120 datasheet and matches the ordering part number suffix "GFM", which denotes the 100-pin LFQFP variant of the R5F526TFAGFM#30.
