Product details
Overview
R5F526TFDGFL#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 hardware-accelerated 3-phase complementary PWM with dead-time control.
For engineers reviewing the R5F526TFDGFL#30 datasheet, R5F526TFDGFL#30 pinout, R5F526TFDGFL#30 application, or R5F526TFDGFL#30 equivalent, this MCU is evaluated for real-time motor phase timing, IEC60730 safety-critical diagnostics, high-resolution PWM waveform generation (260 ps minimum resolution), and simultaneous sampling across three 12-bit A/D converter units - all within a 100-pin LFQFP package rated for –40°C to +85°C operation.
Technical Context
The R5F526TFDGFL#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-based 120 MHz ICLK, independent IWDT oscillator (120 kHz), and configurable peripheral clocks (PCLKA up to 120 MHz, PCLKB/C/D at up to 60–120 MHz).
Motor control is enabled by tightly coupled peripherals: GPTWa (8-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) support synchronous 3-phase/5-phase complementary PWM; HRPWM adds 260 ps timing resolution to GPTW0–GPTW3 outputs; S12ADH provides simultaneous sampling across three 12-bit A/D units (4+4+14 channels); and ELC enables event-triggered module linkage without CPU intervention.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFDGFL#30?
The R5F526TFDGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and optimized memory subsystem enabling no-wait access to both 512 KB code flash and 64 KB SRAM at full speed. The R5F526TFDGFL#30 maintains this rating under industrial temperature conditions (–40°C to +85°C) with proper decoupling and thermal design.
Does the R5F526TFDGFL#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFDGFL#30 includes dedicated hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), register write protection, A/D disconnection diagnostics, and independent watchdog timer (IWDTa) with window function. These are documented in the R01DS0407EJ0120 datasheet and do not require external components. The R5F526TFDGFL#30 implements them natively to reduce software validation effort in safety-critical motor control applications.
What A/D converter configuration does the R5F526TFDGFL#30 provide, and how many channels support simultaneous sampling?
The R5F526TFDGFL#30 includes the S12ADH 12-bit A/D converter with three independent units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 channels. All three units support true simultaneous sampling - critical for field-oriented control - with dedicated sample-and-hold circuits per channel in Units 0 and 1. The R5F526TFDGFL#30 achieves 0.9 µs minimum conversion time per channel when ADCLK runs at 60 MHz.
What is the role of the Event Link Controller (ELC) in the R5F526TFDGFL#30, and how many event signals does it support?
The Event Link Controller (ELC) in the R5F526TFDGFL#30 enables direct hardware-level interconnection between peripherals - such as MTU3d, GPTWa, S12ADH, and CANFD - without CPU intervention. It supports 183 internal event signals, allowing precise, deterministic triggering of A/D conversions, PWM updates, or CAN message transmission based on timer events or external inputs. This eliminates interrupt latency and jitter, making the R5F526TFDGFL#30 ideal for time-critical motor control loops.
Which package and pin count does the R5F526TFDGFL#30 use, and what is its thermal pad configuration?
The R5F526TFDGFL#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package (LFQFP) with 14 × 14 mm body size, 0.5 mm pitch, and an exposed thermal pad on the underside. This pad must be soldered to a PCB copper pour for effective heat dissipation in high-duty-cycle motor control applications. The package is RoHS compliant and rated for operation from –40°C to +85°C (D-version), matching the industrial temperature grade specified for the R5F526TFDGFL#30.
