Renesas R5F566TFGGFB#10

Overview

R5F566TFGGFB#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 code flash, 128 KB SRAM, 32 KB data flash, integrated 3-phase PWM timers (GPTW/MTU3), 12-bit A/D converter with simultaneous sampling across 30 channels, and on-chip TSIP-Lite encryption. It supports IEC60730 Class B compliance and targets real-time motor drive systems requiring high-resolution timing and analog signal acquisition.

For engineers reviewing the R5F566TFGGFB#10 datasheet, R5F566TFGGFB#10 pinout, R5F566TFGGFB#10 application, or R5F566TFGGFB#10 equivalent, this MCU delivers deterministic 195-ps HRPWM timing, dual 12-bit D/A outputs usable as comparator references, CAN 2.0B interface with 32 mailboxes, full-speed USB 2.0 host/function/OTG, and ELC-driven event-triggered peripheral coordination - all within a 144-pin LFQFP package rated for –40°C to +105°C operation.

Technical Context

The R5F566TFGGFB#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 integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent domain clocks: ICLK up to 160 MHz, PCLKA up to 120 MHz for GPTW/MTU3/HRPWM, PCLKB up to 60 MHz for peripherals like SCI/RIIC/CAN, and ADCLK up to 60 MHz for S12ADH.

It features tightly coupled analog subsystems: three 12-bit A/D units (S12ADH) supporting simultaneous sampling across 30 channels with programmable gain amplifiers (6 channels), six analog comparators (CMPC), two 12-bit D/A converters (R12DAb), and temperature sensor interfaced via unit 2 of S12ADH. Safety functions include MPU, register write protection, CAC, CRCA, oscillation-stop detection, and DOC-assisted RAM testing - all aligned with IEC60730 requirements.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F566TFGGFB#10?

The R5F566TFGGFB#10 operates at a maximum frequency of 160 MHz using the 32-bit RXv3 CPU core with single-precision FPU, achieving 928 CoreMark. Its architecture supports IEEE 754 floating-point operations, 111 instructions (including DSP extensions), and little-endian or big-endian data arrangement - all verified in the R01DS0315EJ0130 datasheet Rev.1.30.

Does the R5F566TFGGFB#10 support simultaneous sampling across multiple A/D channels?

Yes, the R5F566TFGGFB#10 integrates three independent 12-bit S12ADH units capable of simultaneous sampling across up to 30 channels (8+8+14). Unit 0 and Unit 1 each include three sample-and-hold circuits, enabling true concurrent acquisition of motor phase currents and DC-link voltage - a capability confirmed in Section 1.1 and Table 1.1 of the official datasheet.

What PWM resolution and complementary output capabilities does the R5F566TFGGFB#10 provide?

The R5F566TFGGFB#10 delivers 10-channel 32-bit GPTW PWM with single-phase, 3-phase, and 5-phase complementary modes, plus 4-channel HRPWM with 195 ps minimum timing resolution at 160 MHz. It supports automatic dead-time insertion, non-overlapping waveform generation, and synchronous counter clearing - all documented for the GPTW and HRPWM modules in pages 6–7 of R01DS0315EJ0130.

Is the R5F566TFGGFB#10 qualified for IEC60730 Class B compliance?

Yes, the R5F566TFGGFB#10 includes dedicated hardware for IEC60730 Class B: oscillation-stop detection, clock frequency accuracy measurement (CAC), CRC calculator (CRCA), DOC-assisted RAM testing, register write protection, and self-diagnostic A/D functions. These features are explicitly listed under "Useful functions for IEC60730 compliance" on page 1 of the datasheet.

What is the package type and thermal rating of the R5F566TFGGFB#10?

The R5F566TFGGFB#10 uses a 144-pin LFQFP package (PLQP0144KA-B, 20 mm × 20 mm, 0.5 mm pitch) and is rated for operation from –40°C to +105°C (G-version). This package includes an exposed thermal pad and supports 5-V tolerant I/O on four pins - specifications confirmed in Table 1.1 (page 10) and package dimension diagrams in the datasheet.
