Renesas R5F566TKAGFP#10

Overview

R5F566TKAGFP#10 from Renesas is a 32-bit RXv3 microcontroller optimized for industrial motor control and power conversion systems, operating at up to 160 MHz with 1 MB code flash, 128 KB SRAM, 32 KB data flash, integrated 3-phase/5-phase PWM timers (GPTW/MTU3), and on-chip FPU supporting IEEE 754 single-precision arithmetic.

For engineers reviewing the R5F566TKAGFP#10 datasheet, R5F566TKAGFP#10 pinout, R5F566TKAGFP#10 application, or R5F566TKAGFP#10 equivalent, key selection considerations include its 144-pin LFQFP package, 195-ps HRPWM timing resolution, dual 12-bit ADC units with PGA support, CAN 2.0B compliance, and IEC 60730 safety features including CAC, CRCA, and register write protection.

Technical Context

The R5F566TKAGFP#10 implements the RXv3 CPU core with 111 instructions, 32×32→64-bit hardware multiplier, and barrel shifter, executing at 160 MHz with 928 CoreMark performance. Its clock system integrates PLL, high-speed on-chip oscillator (16–20 MHz), and low-speed oscillator (240 kHz), enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz).

Motor control capability is anchored in three complementary timer subsystems: 10-channel 32-bit GPTW with synchronous start/stop and dead-time generation; 9-channel 16-bit MTU3d supporting 3-phase inverter PWM with automatic dead-time compensation; and 4-channel HRPWM delivering 195-ps minimum edge placement resolution for precise gate drive timing.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TKAGFP#10?

The R5F566TKAGFP#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This reflects its RXv3 CPU core architecture with hardware FPU, 32×32→64-bit multiplier, and optimized instruction pipeline. The CoreMark benchmark was measured under actual 160 MHz operation with ROM cache enabled, confirming deterministic real-time execution capability essential for motor control loops.

Does the R5F566TKAGFP#10 support IEC 60730 Class B compliance out of the box?

Yes, the R5F566TKAGFP#10 includes multiple hardware features required for IEC 60730 Class B compliance: clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), oscillation-stop detection, independent watchdog timer (IWDT), register write protection, and DOC-assisted RAM testing. These are implemented in silicon and documented in Renesas' functional safety manual R01UM0132EJ0200, enabling certified system-level validation without external components.

What PWM resolution does the R5F566TKAGFP#10 achieve, and how is it realized?

The R5F566TKAGFP#10 achieves a minimum PWM edge placement resolution of 195 ps using its 4-channel High-Resolution PWM (HRPWM) module. This is realized by interpolating the 160 MHz GPTW counter clock with a fine-phase delay circuit synchronized to GPTW0–GPTW3 outputs. The resolution is guaranteed across the full temperature range (–40°C to +105°C) and does not depend on external calibration or software compensation.

How many analog-to-digital converter channels does the R5F566TKAGFP#10 support, and what are their key capabilities?

The R5F566TKAGFP#10 supports 30 total channels across three 12-bit S12ADH ADC units: Unit 0 (8 ch, 3 sample-and-hold circuits), Unit 1 (8 ch, 3 sample-and-hold circuits), and Unit 2 (14 ch). Key capabilities include simultaneous sampling across units, programmable gain amplifier (6 channels, pseudo-differential mode), digital comparison with window detection, and ELC-triggered conversion synchronized to PWM events-enabling precise current/voltage acquisition in motor control applications.

Is the R5F566TKAGFP#10 pin-compatible with other RX66T Group MCUs in the same package?

Yes, the R5F566TKAGFP#10 is pin-compatible with other 144-pin LFQFP variants in the RX66T Group, including R5F566TKJGFP#10 and R5F566TEAGFP#10. All share identical PLQP0144KA-B mechanical dimensions, 0.5 mm pitch, and pin function mapping. However, feature availability (e.g., HRPWM, data flash, ADC units) varies by part number, so firmware and peripheral initialization must be validated per specific device configuration.
