Renesas R5F566TAEGFF#10

Overview

R5F566TAEGFF#10 from Renesas is a 32-bit RXv3 microcontroller designed for high-performance motor control and industrial inverter applications. It operates at up to 160 MHz, integrates 1 MB code flash, 128 KB SRAM (no wait states), 32 KB data flash (100,000 write cycles), and features dual 12-bit ADC units with simultaneous sampling across 30 channels. Its 10-channel 32-bit GPTW timer supports 3-phase complementary PWM with dead-time control, and it includes CAN (ISO 11898-1), full-speed USB 2.0, and TSIP-Lite encryption.

For engineers reviewing the R5F566TAEGFF#10 datasheet, R5F566TAEGFF#10 pinout, R5F566TAEGFF#10 application, or R5F566TAEGFF#10 equivalent, this MCU delivers deterministic real-time control for servo drives, HVAC inverters, and industrial PLCs - with IEC 60730-compliant safety features, 195-ps HRPWM timing resolution, and ELC-based event-driven peripheral coordination without CPU intervention.

Technical Context

The R5F566TAEGFF#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 111-instruction set including DSP extensions. Its clock system uses a PLL fed by an 8–24 MHz external resonator or internal 16/18/20 MHz HOCO, generating independent clocks: ICLK up to 160 MHz (CPU), PCLKA up to 120 MHz (GPTW/MTU3/HRPWM), and PCLKD up to 60 MHz (S12ADH).

Peripheral integration centers on motor control: GPTW provides 10 channels of 32-bit PWM with synchronous start/stop, phase-counting, and A/D trigger generation; MTU3d adds 9 channels of 16-bit complementary PWM with automatic dead-time insertion; HRPWM refines GPTW0–GPTW3 outputs to 195 ps minimum edge resolution. The ELC enables direct inter-module triggering (e.g., timer overflow → ADC conversion) while CPU remains in sleep mode.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAEGFF#10?

The R5F566TAEGFF#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all verified in the official Renesas R01DS0315EJ0130 datasheet Rev.1.30. The R5F566TAEGFF#10 sustains this speed with zero-wait-state access to 128 KB SRAM and optimized ROM cache behavior.

Does the R5F566TAEGFF#10 support IEC 60730 functional safety certification?

Yes, the R5F566TAEGFF#10 includes dedicated hardware features for IEC 60730 compliance: oscillation-stop detection, RAM test assistance via DOC, CRC calculator (CRCA), independent watchdog timer (IWDT) with window function, clock accuracy measurement circuit (CAC), and register write protection. These are documented in Section 1.1 of the R01DS0315EJ0130 datasheet and enable Class B certification without external safety monitors. The R5F566TAEGFF#10 leverages these blocks to reduce software overhead in safety routines.

What package type and pin count does the R5F566TAEGFF#10 use?

The R5F566TAEGFF#10 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size and 0.5 mm pitch. This package supports 110 general-purpose I/O pins, including 4 with 5-V tolerance, and is rated for operation from –40°C to +105°C (G-version). Pin assignments and thermal pad layout are defined in Figure 1-1 of the R01DS0315EJ0130 datasheet.

How many ADC channels and what resolution does the R5F566TAEGFF#10 provide?

The R5F566TAEGFF#10 integrates three 12-bit S12ADH ADC units totaling 30 input channels: Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). Each unit includes dedicated sample-and-hold circuits (3 per unit for Units 0/1), programmable gain amplifiers (6 channels total), and supports simultaneous sampling across units. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK, as specified in Table 1.1 of the R01DS0315EJ0130 datasheet.

What communication interfaces are integrated into the R5F566TAEGFF#10?

The R5F566TAEGFF#10 integrates CAN (1 channel, 32 mailboxes, ISO 11898-1 compliant), full-speed USB 2.0 host/function/OTG, seven SCI channels (including FIFO-buffered SCI11 and LIN-capable SCI12), one I2C interface (RIICa, 400 kbps fast mode), and one RSPI interface (30 Mbps). All interfaces support event linking via ELC for CPU-free operation. These are detailed in Sections 1.1 and Table 1.1 of the R01DS0315EJ0130 datasheet.
