Renesas R5F566TKEDFP#30

Overview

R5F566TKEDFP#30 from Renesas is a 32-bit RXv3 core MCU optimized for industrial motor control, operating at up to 160 MHz with 928 CoreMark performance, integrated 1 MB code flash, 128 KB SRAM, and dedicated high-resolution PWM (195 ps min. resolution) for precise inverter gate timing. It supports IEC60730-compliant safety functions including oscillation-stop detection, RAM self-test, and CRC acceleration.

For engineers reviewing the R5F566TKEDFP#30 datasheet, R5F566TKEDFP#30 pinout, R5F566TKEDFP#30 application, or R5F566TKEDFP#30 equivalent, key selection criteria include its 144-pin LFQFP package, 3-phase/5-phase complementary PWM capability, dual 12-bit ADC units with PGA support, CAN 2.0B interface, and TSIP-Lite encryption engine for secure firmware updates.

Technical Context

The R5F566TKEDFP#30 implements the RXv3 CPU core with single-precision FPU, IEEE 754-compliant floating-point arithmetic, and 111 instructions including DSP extensions. Its clock system combines PLL synthesis with selectable reference sources (8–24 MHz crystal or 16/18/20 MHz HOCO), enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).

Motor control execution relies on tightly coupled peripherals: GPTW timers (10 channels, 32-bit) synchronized to PCLKC for PWM generation, HRPWM circuitry for sub-nanosecond edge placement, MTU3d (9 channels) for 3-phase dead-time compensation, and ELC-driven event chaining to trigger ADC conversions without CPU intervention during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TKEDFP#30?

The R5F566TKEDFP#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's 111-instruction set, single-cycle execution capability, and integrated 32-bit multiplier/divider - enabling deterministic execution of complex motor control algorithms such as field-oriented control (FOC) within tight timing budgets. The R5F566TKEDFP#30 maintains this throughput across its full voltage range (2.7–5.5 V).

Does the R5F566TKEDFP#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TKEDFP#30 includes hardware-accelerated features required for IEC60730 Class B compliance: oscillation-stop detection for main clock, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), DOC-assisted RAM testing, and register write protection. These are implemented in dedicated peripherals - not software libraries - reducing certification effort. The R5F566TKEDFP#30 datasheet explicitly lists these functions under "Useful functions for IEC60730 compliance", confirming their integration into the silicon.

What analog peripherals are integrated into the R5F566TKEDFP#30 for motor current sensing?

The R5F566TKEDFP#30 integrates three 12-bit ADC units totaling 30 channels, with Units 0 and 1 each featuring three programmable gain amplifier (PGA) channels supporting pseudo-differential input. This allows direct connection to shunt resistors for high-accuracy current sensing without external op-amps. Additionally, six analog comparators (CMPC) provide hardware-based overcurrent protection with sub-microsecond response, and two 12-bit DACs can generate reference voltages for comparator thresholds - all coordinated via the Event Link Controller to minimize CPU involvement in critical fault responses.

How does the HRPWM feature of the R5F566TKEDFP#30 improve inverter performance?

The HRPWM circuit in the R5F566TKEDFP#30 delivers minimum timing resolution of 195 ps when operating at 160 MHz, enabling precise placement of rising/falling edges on GPTW0–GPTW3 outputs. This allows accurate dead-time insertion down to ~1 ns, which is essential for preventing shoot-through in high-frequency SiC/GaN inverters. Unlike standard PWM timers, HRPWM operates independently of the main counter, permitting dynamic adjustment of edge timing without disrupting base PWM frequency - a capability critical for adaptive modulation schemes in advanced motor drives using the R5F566TKEDFP#30.

What package and pin count does the R5F566TKEDFP#30 use, and how many GPIOs are available?

The R5F566TKEDFP#30 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package (LFQFP) with 20 mm × 20 mm body and 0.5 mm pitch. It provides 110 general-purpose I/O pins, including 4 pins with 5-V tolerance, 110 with pull-up resistors, 110 with open-drain capability, and 15 with large-current drive. This I/O count supports complex motor control systems requiring multiple PWM outputs, encoder inputs, analog sensor interfaces, and communication buses - all while maintaining signal integrity through dedicated power/ground pin allocation per functional block.
