Renesas R5F566TAEGFH#30

Overview

R5F566TAEGFH#30 from Renesas is a 32-bit RXv3 microcontroller designed for high-performance motor control and industrial real-time applications. It operates at up to 160 MHz, integrates 1 MB code flash, 128 KB SRAM, 32 KB data flash, dual 12-bit ADCs with simultaneous sampling across 30 channels, and 10-channel 32-bit GPTW timers supporting 3-phase complementary PWM. It is deployed in servo drives and inverters requiring precise timing, safety compliance (IEC60730), and integrated USB 2.0 FS host/function capability.

For engineers reviewing the R5F566TAEGFH#30 datasheet, R5F566TAEGFH#30 pinout, R5F566TAEGFH#30 application, or R5F566TAEGFH#30 equivalent, key selection considerations include its 144-pin LFQFP package, 160 MHz CPU with FPU, 195 ps HRPWM resolution, CAN 2.0B interface, and TSIP-Lite encryption engine for secure firmware updates.

Technical Context

The R5F566TAEGFH#30 implements the RXv3 CPU core with single-precision FPU compliant to IEEE 754, enabling deterministic floating-point math for field-oriented control (FOC) algorithms. Its clock system supports PLL multiplication using an 8–24 MHz external resonator or internal 16/18/20 MHz HOCO, delivering ICLK up to 160 MHz while independently configuring PCLKA (120 MHz), PCLKB (60 MHz), and PCLKC (160 MHz) for peripheral domains.

Real-time responsiveness is enhanced by the Event Link Controller (ELC), which enables direct hardware interconnection between 188 internal event sources - such as GPTW compare matches or MTU3 capture events - and peripheral modules like ADC start triggers or port output enables, eliminating CPU intervention during critical timing sequences.

FAQ

What is the maximum operating frequency and CPU core type of the R5F566TAEGFH#30?

The R5F566TAEGFH#30 features a 32-bit RXv3 CPU core with integrated single-precision floating-point unit (FPU), operating at a maximum frequency of 160 MHz. This enables deterministic execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless estimation with sub-microsecond loop times. The R5F566TAEGFH#30 achieves 928 CoreMark performance at this speed, confirming its suitability for real-time industrial applications.

Does the R5F566TAEGFH#30 support simultaneous sampling across multiple ADC channels?

Yes, the R5F566TAEGFH#30 integrates three independent 12-bit S12ADH ADC units totaling 30 input channels, with simultaneous sampling capability across up to 7 channels. This is achieved using dedicated sample-and-hold circuits in Units 0 and 1 (3 channels each) and Unit 2 (14 channels). The R5F566TAEGFH#30 uses hardware triggers from GPTW or MTU3 timers to synchronize conversions - essential for accurate current reconstruction in dual-shunt motor control topologies.

What safety certifications and features does the R5F566TAEGFH#30 support for industrial use?

The R5F566TAEGFH#30 includes built-in features aligned with IEC60730 Class B compliance, including oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, self-diagnostic ADC functions, and register write protection. It also integrates a memory protection unit (MPU), Trusted Memory (TM) for code flash blocks 8–9, and TSIP-Lite for AES encryption. These capabilities make the R5F566TAEGFH#30 suitable for safety-critical industrial applications without requiring external safety monitors.

What package type and pin count does the R5F566TAEGFH#30 use?

The R5F566TAEGFH#30 is housed in a PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package measuring 20 × 20 mm with 0.5 mm pitch. It provides 110 general-purpose I/O pins, including 4 with 5-V tolerance, 15 large-current outputs, and dedicated pins for USB DP/DM, CAN TX/RX, and high-resolution PWM outputs. This package is RoHS-compliant and optimized for thermal dissipation in motor control applications.

Can the R5F566TAEGFH#30 operate with a 5 V supply voltage?

Yes, the R5F566TAEGFH#30 supports a wide VCC supply range of 2.7 V to 5.5 V, making it compatible with standard 5 V industrial power rails. Its analog supply AVCC0/AVCC1/AVCC2 accepts 3.0 V to 5.5 V (with VCC ≤ AVCC), and four GPIO pins are explicitly rated for 5-V tolerance. When USB is used, VCC_USB must be regulated to 3.0–3.6 V, but the R5F566TAEGFH#30 internally manages domain isolation to maintain robust operation across mixed-voltage subsystems.
