Renesas R5F566TAFGFL#50

Overview

R5F566TAFGFL#50 from Renesas is a 32-bit RXv3 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 across 10 GPTW channels. It supports IEC60730-compliant safety functions and targets inverter-driven HVAC, servo drives, and industrial PLCs.

For engineers reviewing the R5F566TAFGFL#50 datasheet, R5F566TAFGFL#50 pinout, R5F566TAFGFL#50 application, or R5F566TAFGFL#50 equivalent, key selection criteria include its 160-MHz PWM timing resolution (195 ps minimum), dual 12-bit A/D converters with simultaneous sampling across 30 channels, integrated TSIP-Lite encryption, CAN 2.0B compliance, and full-speed USB 2.0 host/function capability.

Technical Context

The R5F566TAFGFL#50 implements the RXv3 CPU core with single-precision FPU, IEEE 754-compliant floating-point arithmetic, and 111-instruction set including DSP extensions. Its clock architecture uses PLL-synthesized ICLK up to 160 MHz derived from 8–24 MHz external crystal or internal 16–20 MHz HOCO, while peripheral clocks (PCLKA/B/C/D) are independently configurable - PCLKC at 160 MHz synchronizes GPTW/HRPWM counter references.

Safety-critical operation is enabled by hardware-assisted features: oscillation-stop detection, CAC for clock accuracy monitoring, CRCA with selectable polynomials, register write protection, and Trusted Memory (TM) locking blocks 8–9 of code flash. The ELC allows event-triggered peripheral coordination without CPU intervention - essential for deterministic motor control loop timing.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAFGFL#50?

The R5F566TAFGFL#50 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency with FPU, cache, and pipeline optimizations - enabling complex motor control algorithms and real-time signal processing within strict timing budgets. The R5F566TAFGFL#50 sustains this performance across its full temperature range (–40°C to +105°C) with no derating.

Does the R5F566TAFGFL#50 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TAFGFL#50 includes hardware features required for IEC60730 Class B: oscillation-stop detection, clock accuracy measurement circuit (CAC), CRC calculator (CRCA), independent watchdog timer (IWDT), RAM test assist via DOC, and register write protection. These are documented in the R01DS0315EJ0130 datasheet and do not require external components - though system-level validation remains the designer's responsibility. The R5F566TAFGFL#50 is rated for industrial temperature range (–40°C to +105°C), supporting robust operation in safety-critical environments.

What PWM resolution and channel count does the R5F566TAFGFL#50 provide for motor control?

The R5F566TAFGFL#50 delivers 10-channel 32-bit GPTW PWM plus 4-channel HRPWM with a minimum timing resolution of 195 ps at 160 MHz - enabling precise dead-time insertion and phase alignment for 3-phase and 5-phase inverters. It supports single-phase complementary (10 outputs), 3-phase complementary (3 outputs), and 5-phase complementary (2 outputs) modes. All PWM outputs are hardware-linked to ADC triggers via ELC, ensuring deterministic sampling synchronized to switching edges - a capability confirmed in the R5F566TAFGFL#50 datasheet section 1.1 and Table 1.1.

How many analog input channels and what ADC architecture does the R5F566TAFGFL#50 support?

The R5F566TAFGFL#50 integrates three 12-bit S12ADH units totaling 30 analog input channels: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). It supports simultaneous sampling across all units, programmable gain amplifiers (6 channels), and digital comparison. Conversion time is 0.9 µs per channel at 60 MHz ADCLK. This architecture is explicitly specified for the 144-pin variant in the R01DS0315EJ0130 datasheet pages 9 and 11, confirming full 30-channel capability for R5F566TAFGFL#50.

What package type and pin count does the R5F566TAFGFL#50 use?

The R5F566TAFGFL#50 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with PLQP0144KA-B designation: 20 × 20 mm body size, 0.5 mm pitch, and an exposed thermal pad. It provides 110 general-purpose I/O pins, including 4 with 5-V tolerance, 110 with pull-up capability, and 15 with large-current drive. This package is confirmed in the "Outline of Specifications" table (page 10) and "Comparison of Functions" table (page 11) of the R01DS0315EJ0130 datasheet - uniquely assigned to the 1 MB flash, 128 KB SRAM, and full-feature variant of the RX66T Group.
