Renesas R5F566TAEGFN#10

Overview

R5F566TAEGFN#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 code flash, 128 KB SRAM, 32 KB data flash, integrated 3-phase PWM timers (GPTW/MTU3), 12-bit A/D converter with simultaneous sampling across three units, and on-chip TSIP-Lite encryption. It supports IEC60730 Class B compliance and targets real-time motor drive systems requiring high-resolution timing and functional safety.

For engineers reviewing the R5F566TAEGFN#10 datasheet, R5F566TAEGFN#10 pinout, R5F566TAEGFN#10 application, or R5F566TAEGFN#10 equivalent, key selection criteria include 160-MHz PWM timing resolution (195 ps), 32-channel CAN mailbox support, 110 GPIOs with 5-V tolerance, dual 12-bit DAC outputs usable as comparator references, and PLQP0144KA-B 144-pin LFQFP package compatibility.

Technical Context

The R5F566TAEGFN#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian mode. Its clock system integrates PLL, HOCO (16–20 MHz), LOCO (240 kHz), and main oscillator (8–24 MHz) with independent peripheral clock domains (PCLKA up to 120 MHz, PCLKC up to 160 MHz) enabling precise timing separation between control loops and communication peripherals.

Motor control is enabled by tightly coupled hardware: GPTW (10-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) share PCLKC for synchronized counter operation, while HRPWM provides sub-200-ps edge placement on four GPTW channels. ELC links analog triggers (A/D start, comparator output) directly to timer actions without CPU intervention, supporting deterministic response in safety-critical drives.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAEGFN#10?

The R5F566TAEGFN#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip 32-bit multiplier/divider, and optional 8-KB ROM cache that enables one-cycle instruction fetch up to 160 MHz when hit. The R5F566TAEGFN#10 sustains this speed across its full memory map and peripheral bus architecture.

Does the R5F566TAEGFN#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F566TAEGFN#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), RAM test-assisting function via DOC, CRC calculator (CRCA), independent watchdog timer (IWDTa), and register write protection. These are documented in the R01DS0315EJ0130 datasheet and do not require external components to implement self-test routines for safety-critical motor control applications using the R5F566TAEGFN#10.

What package type and pin count does the R5F566TAEGFN#10 use?

The R5F566TAEGFN#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, including 4 with 5-V tolerance, and integrates dedicated pins for motor control (MTIOCx, GTIOCA/B), analog functions (ADTRGx, CMPCx), and USB 2.0 (USB_DP/DM). This package is thermally enhanced with an exposed pad for improved heat dissipation in high-power inverter designs.

How many A/D converter channels does the R5F566TAEGFN#10 support, and what sampling capability does it offer?

The R5F566TAEGFN#10 integrates the S12ADH 12-bit A/D converter with a total of 30 input channels across three units: Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). Units 0 and 1 each include three sample-and-hold circuits, enabling true simultaneous sampling of up to six analog signals-critical for three-phase current sensing. Conversion time is as low as 0.9 µs per channel when ADCLK runs at 60 MHz, and triggers can be sourced from GPTW, MTU3, or ELC events for deterministic timing in the R5F566TAEGFN#10.

What security features are implemented in the R5F566TAEGFN#10 for firmware protection?

The R5F566TAEGFN#10 implements Trusted Secure IP Lite (TSIP-Lite) with AES-128/256 encryption (ECB/CBC/GCM/XTS modes), true random number generation, and secure key management. It also includes Trusted Memory (TM) to block readout from code flash blocks 8 and 9, MPU for eight configurable memory protection areas, and register write protection to prevent accidental overwrites. These features enable secure boot, encrypted firmware updates, and tamper-resistant operation in industrial applications deploying the R5F566TAEGFN#10.
