Renesas R5F566TKCGFB#10

Overview

R5F566TKCGFB#10 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 160 MHz with 928 CoreMark performance, 1 MB on-chip code flash, 128 KB SRAM (no wait states), and integrated 3-phase/5-phase complementary PWM timers - deployed in HVAC compressors, servo drives, and industrial PLCs.

For engineers reviewing the R5F566TKCGFB#10 datasheet, R5F566TKCGFB#10 pinout, R5F566TKCGFB#10 application, or R5F566TKCGFB#10 equivalent, key selection criteria include 160-MHz GPTW timer resolution, 195-ps HRPWM timing control, IEC60730 safety features (CAC, IWDT, RAM test assist), CAN 2.0B compliance, and 144-pin LFQFP package with 110 GPIOs including 5-V-tolerant inputs.

Technical Context

The R5F566TKCGFB#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian support. It integrates dual-clock domain architecture: ICLK up to 160 MHz for CPU/core logic, PCLKA up to 120 MHz for GPTW/MTU3/HRPWM, and PCLKD up to 60 MHz for S12ADH ADC operation.

Its motor control subsystem combines ten 32-bit GPTW channels (supporting single-/3-/5-phase complementary PWM), nine 16-bit MTU3d channels, and four-channel HRPWM with 195-ps minimum timing resolution - all synchronized via PCLKC and coordinated by ELC event linking without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TKCGFB#10?

The R5F566TKCGFB#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, single-cycle instruction execution, and on-chip cache behavior - validated under conditions matching the datasheet's Rev.1.30 test methodology. The R5F566TKCGFB#10 sustains this performance across its full operating temperature range (–40°C to +105°C) with no derating.

Does the R5F566TKCGFB#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TKCGFB#10 includes dedicated hardware for IEC60730 Class B compliance: clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with window function, oscillation-stop detection, RAM test assist via DOC, and register write protection. These features are documented in the R01DS0315EJ0130 datasheet and do not require external components to meet functional safety diagnostics requirements.

What PWM resolution does the R5F566TKCGFB#10 achieve, and how is it implemented?

The R5F566TKCGFB#10 achieves a minimum PWM timing resolution of 195 ps using its four-channel High-Resolution PWM (HRPWM) module, which fine-tunes the edge placement of waveforms generated by GPTW0–GPTW3. This resolution is realized at 160 MHz system clock and is confirmed in the "High-resolution PWM waveform generation circuit" section of the R01DS0315EJ0130 datasheet - enabling precise dead-time control for SiC/GaN power stages.

How many analog-to-digital converter channels does the R5F566TKCGFB#10 support, and what is their configuration?

The R5F566TKCGFB#10 integrates three independent 12-bit S12ADH ADC units totaling 30 channels: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). Each unit supports programmable sampling time, group scan modes, and digital comparison - with simultaneous sampling across units enabled for multi-axis motor current sensing.

What package type and pin count does the R5F566TKCGFB#10 use, and what are its thermal characteristics?

The R5F566TKCGFB#10 uses the PLQP0144KA-B package: a 144-pin low-profile quad flat package with 20 × 20 mm body size, 0.5 mm pitch, and exposed thermal pad. It is rated for operation from –40°C to +105°C (G-grade), with thermal resistance θJA = 30.2°C/W per Renesas' published package data - enabling reliable operation in enclosed industrial enclosures without forced airflow.
