Renesas R5F566TKGGFP#10

Overview

R5F566TKGGFP#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial real-time 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 3-phase/5-phase complementary PWM generation for inverter drive systems.

For engineers reviewing the R5F566TKGGFP#10 datasheet, R5F566TKGGFP#10 pinout, R5F566TKGGFP#10 application, or R5F566TKGGFP#10 equivalent, key selection considerations include its 144-pin LFQFP package, 160-MHz GPTW timer with 195-ps HRPWM resolution, dual 12-bit ADC units supporting simultaneous sampling across 30 channels, CAN 2.0B compliance, and IEC60730 safety features including CAC, CRCA, and register write protection.

Technical Context

The R5F566TKGGFP#10 implements the RXv3 CPU core with single-precision FPU, IEEE 754-compliant floating-point arithmetic, and 111 instructions including DSP extensions. Its clock system supports PLL multiplication using 8–24 MHz external crystals or internal 16–20 MHz HOCO, enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) for precise timing isolation between motor control timers and communication peripherals.

Real-time motor control is enabled by tightly coupled hardware: ELC links GPTW/MTU3 events to A/D conversion triggers without CPU intervention; POE3B and POEG provide hardware fault response for PWM output disable during short-circuit detection; and the 32-channel CAN module supports mailbox-based filtering and transmission prioritization for deterministic fieldbus communication in industrial drives.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TKGGFP#10?

The R5F566TKGGFP#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency with FPU and cache support, enabling complex motor control algorithms such as Field-Oriented Control (FOC) to execute within tight real-time deadlines. The R5F566TKGGFP#10 maintains this performance across its full industrial temperature range (–40°C to +105°C).

Does the R5F566TKGGFP#10 support simultaneous sampling across all 30 ADC channels?

No - the R5F566TKGGFP#10 supports simultaneous sampling only within each of its three independent S12ADH units: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels, no sample-and-hold). While all 30 channels can be scanned in sequence, true simultaneous conversion is limited to up to 7 channels across Units 0 and 1 when using their dedicated sample-and-hold circuits. The R5F566TKGGFP#10's architecture enables synchronized start triggers across units for near-simultaneous acquisition in multi-phase motor current sensing.

What safety certifications and self-test features does the R5F566TKGGFP#10 include for IEC60730 compliance?

The R5F566TKGGFP#10 integrates multiple IEC60730 Class B–compliant features: oscillation-stop detection for main clock failure, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assisting function via DOC, register write protection, and independent watchdog timer (IWDT) with windowing. These are documented in Renesas' R01DS0315EJ0130 datasheet and enable certified self-diagnostic routines without external components. The R5F566TKGGFP#10 also supports Trusted Secure IP Lite for secure boot and firmware integrity verification.

What is the resolution and timing capability of the HRPWM feature in the R5F566TKGGFP#10?

The R5F566TKGGFP#10's High-Resolution PWM (HRPWM) provides a minimum timing resolution of 195 ps when operating the GPTW timer at 160 MHz. This applies specifically to GPTW0 through GPTW3 channels and enables precise dead-time control for SiC and GaN power stages. The R5F566TKGGFP#10 uses this capability to generate non-overlapping gate drive signals with sub-nanosecond accuracy, directly improving inverter efficiency and reducing electromagnetic interference in high-frequency motor drives.

Which package and pin count does the R5F566TKGGFP#10 use, and what are its key mechanical specifications?

The R5F566TKGGFP#10 uses a 144-pin Low-Profile Quad Flat Package (LFQFP) with PLQP0144KA-B footprint: 20 mm × 20 mm body size, 0.5 mm pitch, and an exposed thermal pad. It supports 110 general-purpose I/O pins, including 4 with 5-V tolerance, and is rated for operation from –40°C to +105°C. This package provides the highest I/O density and analog channel count among RX66T variants, making it optimal for complex motor control designs requiring extensive sensor and actuator interfacing. The R5F566TKGGFP#10's pinout is fully documented in the official Renesas datasheet R01DS0315EJ0130.
