Renesas R5F526TFAGFL#10

Overview

R5F526TFAGFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and power conversion, featuring a 120 MHz CPU core, 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. It supports IEC60730 safety compliance and operates across –40°C to +105°C.

For engineers reviewing the R5F526TFAGFL#10 datasheet, R5F526TFAGFL#10 pinout, R5F526TFAGFL#10 application, or R5F526TFAGFL#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit ADC units, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.

Technical Context

The R5F526TFAGFL#10 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 interrupt-heavy motor control loops. Its clock system integrates a PLL fed by an 8–24 MHz crystal, internal HOCO/LOCO oscillators, and independent IWDT-dedicated 120 kHz oscillator.

Peripheral coordination is managed via the Event Link Controller (ELC), enabling 183 internal event signals-including MTU3d timer triggers, GPTWa compare matches, and ADC start requests-to initiate module operations without CPU intervention, even during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFAGFL#10?

The R5F526TFAGFL#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all critical for deterministic motor control loop timing. The R5F526TFAGFL#10 sustains this performance with zero wait-state access to both 512 KB flash and 64 KB SRAM.

Does the R5F526TFAGFL#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFAGFL#10 includes multiple hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test-assisting function via DOC, CRC calculator (CRCA), register write protection, independent watchdog timer (IWDT) with window function, and self-diagnostic A/D converter disconnection detection. These are documented in the R01DS0407EJ0120 datasheet and require no external components to implement baseline safety checks. The R5F526TFAGFL#10 is validated for use in safety-critical motor control applications.

What PWM resolution and complementary output capability does the R5F526TFAGFL#10 provide?

The R5F526TFAGFL#10 delivers 260 ps minimum timing resolution via its HRPWM circuit applied to GPTW0–GPTW3 outputs - enabling precise dead-time control for SiC/GaN power stages. It supports 10 single-phase, 3 three-phase, and 2 five-phase complementary PWM outputs with automatic dead-time insertion, non-overlapping waveform generation, and synchronous start/stop across channels. This capability is intrinsic to the R5F526TFAGFL#10's GPTWa and MTU3d timers and requires no software overhead.

How many ADC channels and sampling modes does the R5F526TFAGFL#10 support?

The R5F526TFAGFL#10 integrates three 12-bit S12ADH ADC units totaling 22 input channels: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). It supports simultaneous sampling across all three units, scan modes (single, continuous, 3-group), group priority control, and digital comparison with window detection. Each unit includes dedicated sample-and-hold circuits - a key capability of the R5F526TFAGFL#10 for accurate current reconstruction in motor control.

What package type and pin count does the R5F526TFAGFL#10 use?

The R5F526TFAGFL#10 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package with 14 × 14 mm body size and 0.5 mm pitch. It provides 82 general-purpose I/O pins, including 2 pins with 5-V tolerance, 15 high-current outputs, and dedicated pins for CAN FD, multiple SCI/RSCI interfaces, and HRPWM outputs. This package is explicitly assigned to the R5F526TFAGFL#10 in Renesas documentation and supports industrial temperature range (–40°C to +105°C).
