Renesas R5F566TEFDFL#10

Overview

R5F566TEFDFL#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 reprogrammable data flash, and integrated high-resolution PWM (195 ps minimum resolution) for precise 3-phase/5-phase inverter gate timing.

For engineers reviewing the R5F566TEFDFL#10 datasheet, R5F566TEFDFL#10 pinout, R5F566TEFDFL#10 application, or R5F566TEFDFL#10 equivalent, key selection criteria include its 110 GPIOs (4× 5-V tolerant), dual 12-bit ADC units with PGA support, embedded TSIP-Lite encryption, IEC60730 safety features, and CAN 2.0B compliance - all in a 144-pin LFQFP (20 × 20 mm, 0.5 mm pitch) package.

Technical Context

The R5F566TEFDFL#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 111-instruction set including DSP extensions. It integrates three independent 12-bit A/D converter units (S12ADH) supporting simultaneous sampling across 30 channels, with programmable gain amplifiers on six channels for direct current-sense signal conditioning.

Its timer subsystem combines ten 32-bit GPTW channels (160 MHz operation), nine 16-bit MTU3d channels, and four HRPWM channels synchronized to GPTW outputs - enabling real-time dead-time compensation, phase-counting, and 3-phase complementary PWM generation without CPU intervention via ELC-triggered event linking.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEFDFL#10?

The R5F566TEFDFL#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - enabling deterministic real-time response in motor control loops. The R5F566TEFDFL#10 sustains this speed with zero wait-state access to 128 KB SRAM and optimized flash cache behavior.

Does the R5F566TEFDFL#10 support simultaneous sampling across multiple analog input channels?

Yes, the R5F566TEFDFL#10 integrates three independent 12-bit S12ADH A/D converter units with dedicated sample-and-hold circuits on six channels (three per unit). This architecture enables true simultaneous sampling of up to three phase currents in motor control applications, with <10 ns inter-channel skew. The R5F566TEFDFL#10 supports group scan modes and hardware triggers from GPTW/MTU3 to align conversions precisely with PWM switching events.

What safety certifications and built-in diagnostic features does the R5F566TEFDFL#10 provide for IEC60730 compliance?

The R5F566TEFDFL#10 includes oscillation-stop detection, clock frequency accuracy measurement (CAC), RAM test assistance via DOC, CRC calculator (CRCA), register write protection, and self-diagnostic A/D functions - all required for Class B compliance. These features are implemented in hardware and documented in Renesas' IEC60730 safety manual. The R5F566TEFDFL#10 also supports Trusted Memory to protect critical firmware blocks and independent watchdog timers with windowing functionality.

Can the R5F566TEFDFL#10 generate 3-phase complementary PWM waveforms with automatic dead-time insertion?

Yes, the R5F566TEFDFL#10's GPTW and MTU3d timers support hardware-generated 3-phase complementary PWM with configurable dead time. GPTW provides 10 output channels in single-phase mode or 3 channels in 3-phase mode, while MTU3d offers 2 additional 3-phase channels. Dead-time values are programmable per channel, and the R5F566TEFDFL#10 automatically inserts non-overlapping intervals to prevent shoot-through in inverter bridge drivers without CPU intervention.

What is the package type and pin count of the R5F566TEFDFL#10, and are the I/O pins 5-V tolerant?

The R5F566TEFDFL#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. It provides 110 general-purpose I/O pins, of which four are explicitly rated for 5-V tolerance - enabling direct interfacing with legacy 5 V sensors and logic without external level shifters. All I/Os support pull-up resistors, open-drain outputs, and configurable drive strength.
