Renesas R5F526TFBGFL#10

Overview

R5F526TFBGFL#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 R5F526TFBGFL#10 datasheet, R5F526TFBGFL#10 pinout, R5F526TFBGFL#10 application, or R5F526TFBGFL#10 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, 3-phase/5-phase complementary PWM generation, simultaneous sampling across three 12-bit A/D units, and Trusted Secure IP Lite encryption support.

Technical Context

The R5F526TFBGFL#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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) provide synchronized PWM outputs with dead-time insertion and phase-counting; HRPWM adds 260 ps fine timing control to GPTW0–GPTW3 outputs; S12ADH delivers simultaneous sampling across 23 analog inputs via three sample-and-hold units.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFBGFL#10?

The R5F526TFBGFL#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip FPU, and zero-wait-state access to 512 KB flash and 64 KB SRAM - enabling deterministic real-time response in motor control applications.

Does the R5F526TFBGFL#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFBGFL#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, A/D converter disconnection check, clock accuracy measurement circuit, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, CRCA, and register write protection. These are documented in the R01DS0407EJ0120 datasheet and require no external components to implement.

What PWM configurations does the R5F526TFBGFL#10 support for 3-phase inverter control?

The R5F526TFBGFL#10 supports multiple 3-phase PWM modes: MTU3d provides 3-channel complementary PWM with automatic dead-time insertion and fault protection; GPTWa offers 3-channel 3-phase complementary PWM with synchronous start/stop; and HRPWM adds 260 ps timing resolution to GPTW0–GPTW3 outputs for ultra-precise dead-time tuning - all usable concurrently for multi-inverter systems.

How many analog input channels can be sampled simultaneously on the R5F526TFBGFL#10?

The R5F526TFBGFL#10 supports simultaneous sampling across 23 analog input channels using three independent sample-and-hold units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). This capability is essential for vector control algorithms requiring synchronized current and voltage measurements in motor drives.

What package type and pin count does the R5F526TFBGFL#10 use?

The R5F526TFBGFL#10 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package measuring 14 mm × 14 mm with 0.5 mm pitch and an exposed thermal pad. It provides 82 general-purpose I/O pins, including 2 pins with 5-V tolerance and 15 high-current output pins - optimized for high-density motor control PCB layouts.
