Renesas R5F566TFBGFP#10

Overview

R5F566TFBGFP#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 160 MHz with 928 CoreMark performance, 1 MB on-chip code flash, 128 KB SRAM (no wait states), and integrated high-resolution PWM (195 ps minimum resolution) for precise 3-phase/5-phase inverter gate timing.

For engineers reviewing the R5F566TFBGFP#10 datasheet, R5F566TFBGFP#10 pinout, R5F566TFBGFP#10 application, or R5F566TFBGFP#10 equivalent, this MCU delivers deterministic real-time control with simultaneous sampling across three 12-bit A/D units (30 channels total), 32-channel CAN interface, full-speed USB 2.0 host/function/OTG, and IEC60730-compliant safety features including oscillation-stop detection, RAM ECC, and trusted secure IP Lite encryption.

Technical Context

The R5F566TFBGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and configurable endian support. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).

Real-time motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers with synchronous start/stop and dead-time generation, 9-channel MTU3d for 3-phase complementary PWM, 4-channel HRPWM with sub-nanosecond edge placement, and ELC-driven event chaining that triggers A/D conversion or timer actions without CPU intervention during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TFBGFP#10?

The R5F566TFBGFP#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency with single-cycle instruction execution, on-chip FPU, and optimized memory subsystem-including zero-wait-state access to 128 KB SRAM and cache-hit performance up to 160 MHz. The R5F566TFBGFP#10 sustains this performance under full peripheral load in industrial ambient conditions.

Does the R5F566TFBGFP#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TFBGFP#10 includes multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assisting function via DOC, independent watchdog timer (IWDTa), and register write protection. These are implemented in silicon and documented in the R01DS0315EJ0130 datasheet-enabling certified safety firmware development without external components. The R5F566TFBGFP#10 also supports Trusted Memory and MPU for secure code partitioning.

What analog sensing capabilities does the R5F566TFBGFP#10 provide for motor current measurement?

The R5F566TFBGFP#10 integrates three 12-bit S12ADH A/D converter units totaling 30 channels, with dedicated sample-and-hold circuits across two units (8+8 channels) for simultaneous current sampling. It includes a programmable gain amplifier (PGA) supporting pseudo-differential inputs on six channels-ideal for shunt-based current sensing with noise rejection. Conversion time is as low as 0.9 µs per channel at 60 MHz ADCLK, and triggers can be synchronized to GPTW/MTU3 events for precise alignment with PWM switching edges. All these capabilities are present in the R5F566TFBGFP#10.

Can the R5F566TFBGFP#10 generate 3-phase complementary PWM waveforms with hardware dead-time insertion?

Yes, the R5F566TFBGFP#10 supports hardware dead-time insertion for 3-phase complementary PWM through both its MTU3d and GPTW peripherals. MTU3d provides automatic dead-time specification and non-overlapping waveform generation for inverter gate driving, while GPTW offers configurable dead-time registers per channel. The HRPWM module further refines edge timing down to 195 ps resolution. These functions operate independently of CPU load and are fully supported in the R5F566TFBGFP#10's 144-pin LFQFP package with dedicated MTIOC and GTIOC pins.

What is the package type and pin count of the R5F566TFBGFP#10?

The R5F566TFBGFP#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B: 20 mm × 20 mm body size, 0.5 mm pitch, and exposed thermal pad. It provides 110 general-purpose I/O pins-including 4 with 5-V tolerance, 15 high-current outputs, and dedicated pins for MTU3/GPTW PWM, A/D triggers, USB, CAN, and SCI interfaces. This package is confirmed in the R01DS0315EJ0130 datasheet and matches the "BGFP" suffix designation in the R5F566TFBGFP#10 ordering code.
