Renesas R5F566TABDFL#10

Overview

R5F566TABDFL#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 160 MHz with 1 MB on-chip code flash, 128 KB SRAM (no wait states), 32 KB data flash (100,000 write cycles), and integrated high-resolution PWM (195 ps minimum timing resolution) for precise 3-phase/5-phase inverter gate driving.

For engineers reviewing the R5F566TABDFL#10 datasheet, R5F566TABDFL#10 pinout, R5F566TABDFL#10 application, or R5F566TABDFL#10 equivalent, key selection considerations include its 144-pin LFQFP package, dual 12-bit A/D converters with simultaneous sampling across 30 channels, embedded TSIP-Lite encryption, IEC60730 safety support, and dedicated HRPWM/MTU3/GPTW timer subsystems for real-time motor phase control.

Technical Context

The R5F566TABDFL#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian mode. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent domain clocks-ICLK (160 MHz), PCLKA (120 MHz), PCLKB/C/D (up to 160/60 MHz)-enabling concurrent high-speed computation and peripheral operation.

Motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW timers with dead-time generation and synchronous start/stop, 9-channel 16-bit MTU3d supporting 3-phase complementary PWM, and 4-channel HRPWM delivering 195 ps edge placement resolution. All are coordinated via the Event Link Controller (ELC) to trigger A/D conversion, comparator events, or port output disable without CPU intervention.

The R5F566TABDFL#10 operates at a maximum frequency of 160 MHz using the 32-bit RXv3 CPU core, achieving 928 CoreMark performance. It supports single-cycle instruction execution, IEEE 754-compliant floating-point operations, and configurable little/big-endian data handling-all verified in the official R01DS0315EJ0130 datasheet.

Does the R5F566TABDFL#10 support simultaneous sampling across all 30 A/D channels?

Yes, the R5F566TABDFL#10 integrates three independent 12-bit S12ADH A/D units (Unit 0: 8 ch, Unit 1: 8 ch, Unit 2: 14 ch) with dedicated sample-and-hold circuits for Units 0 and 1. Hardware-triggered simultaneous sampling across all 30 channels is supported via ELC-linked MTU3/GPTW triggers, as confirmed in Section 1.1 of the R01DS0315EJ0130 datasheet.

What PWM resolution and channel count does the R5F566TABDFL#10 provide for motor control?

The R5F566TABDFL#10 delivers 4-channel High-Resolution PWM (HRPWM) with a minimum timing resolution of 195 ps at 160 MHz, plus 10-channel 32-bit GPTW and 9-channel 16-bit MTU3d timers. These support single-phase, 3-phase, and 5-phase complementary PWM modes with hardware dead-time insertion-fully documented in Table 1.1 and Section 1.1 of the R01DS0315EJ0130 datasheet.

Is the R5F566TABDFL#10 qualified for IEC60730 Class B safety compliance?

Yes, the R5F566TABDFL#10 includes dedicated hardware features for IEC60730 Class B compliance: main clock oscillation stop detection, RAM test assist (via DOC), CRC calculator (CRCA), register write protection, analog input disconnection detection, and clock frequency accuracy measurement (CAC). These are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0315EJ0130 datasheet.

What package type and pin count does the R5F566TABDFL#10 use?

The R5F566TABDFL#10 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size, 0.5 mm pitch, and exposed thermal pad. This matches the "144-pin LFQFP" specification in Table 1.1 and Package Outline Diagrams of the R01DS0315EJ0130 datasheet Rev.1.30.
