Renesas R5F566TAAGFH#30

Overview

R5F566TAAGFH#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial real-time 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 generation for inverter drive systems.

For engineers reviewing the R5F566TAAGFH#30 datasheet, R5F566TAAGFH#30 pinout, R5F566TAAGFH#30 application, or R5F566TAAGFH#30 equivalent, key selection considerations include its 144-pin LFQFP package, 160-MHz GPTW timer with 195-ps HRPWM resolution, dual 12-bit ADC units supporting simultaneous sampling across 30 channels, CAN 2.0B compliance, and IEC60730 safety features including CAC, CRCA, and register write protection.

Technical Context

The R5F566TAAGFH#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian support. 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) for precise timing control of GPTW, MTU3, and HRPWM modules.

Real-time motor control is enabled by tightly coupled peripherals: 10-channel 32-bit GPTW with dead-time insertion and synchronous start/stop, 9-channel 16-bit MTU3d for 3-phase PWM, 4-channel HRPWM with 195-ps minimum timing resolution, and ELC-driven event chaining that allows autonomous module interaction without CPU intervention during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TAAGFH#30?

The R5F566TAAGFH#30 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance. This benchmark reflects real-world execution efficiency of the RXv3 CPU core with its 32-bit architecture, single-cycle instruction execution, and integrated FPU. The R5F566TAAGFH#30 sustains this performance across its full voltage range (2.7–5.5 V) and temperature range (–40°C to +105°C), making it suitable for demanding real-time motor control tasks where deterministic timing is critical.

Does the R5F566TAAGFH#30 support simultaneous sampling across all 30 ADC channels?

The R5F566TAAGFH#30 supports simultaneous sampling across up to 30 channels using three independent 12-bit S12ADH units-Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels)-each with dedicated sample-and-hold circuits. While full 30-channel simultaneous capture requires coordinated triggering via ELC-linked timers like GPTW or MTU3, the hardware architecture enables true concurrent acquisition across all units. This capability is essential for vector control algorithms requiring synchronized current and voltage measurements in motor drive applications.

What safety certifications and built-in functions does the R5F566TAAGFH#30 provide for IEC60730 compliance?

The R5F566TAAGFH#30 includes multiple hardware-assisted features for IEC60730 Class B compliance: oscillation-stop detection for main clock, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOC) for RAM testing, independent watchdog timer (IWDT) with dedicated 120-kHz oscillator, and register write protection. These functions are implemented in silicon-not software-and are documented in Renesas Application Note R01AN3815EJ0100. The R5F566TAAGFH#30 also supports Trusted Memory blocks 8–9 to prevent unauthorized code access.

How many PWM output channels does the R5F566TAAGFH#30 support, and what is the minimum timing resolution?

The R5F566TAAGFH#30 supports up to 10 single-phase, 3 three-phase, and 2 five-phase complementary PWM outputs via its 10-channel GPTW timer, plus 4 additional high-resolution PWM (HRPWM) channels derived from GPTW0–GPTW3. The HRPWM achieves a minimum timing resolution of 195 ps when operating at 160 MHz, enabling precise edge placement for dead-time control and reduced electromagnetic interference in inverter gate drivers. All PWM outputs are fully configurable via registers and can be triggered autonomously via ELC events.

Is the R5F566TAAGFH#30 pin-compatible with other RX66T Group MCUs such as R5F566TAADFH#30 or R5F566TADGH#30?

No, the R5F566TAAGFH#30 is not pin-compatible with R5F566TAADFH#30 or R5F566TADGH#30. Although all belong to the RX66T Group and share architectural similarities, the R5F566TAAGFH#30 uses a 144-pin LFQFP package (PLQP0144KA-B), while R5F566TAADFH#30 uses the same package but differs in memory mapping and peripheral enablement, and R5F566TADGH#30 uses a 100-pin LFQFP (PLQP0100KB-B) with fewer GPIOs and no USB interface. PCB layout must be redesigned for any substitution; no drop-in replacement exists within the RX66T family.
