For engineers reviewing the R5F566NDDGBG#20 datasheet, R5F566NDDGBG#20 pinout, R5F566NDDGBG#20 application, or R5F566NDDGBG#20 equivalent, key selection criteria include its 144-pin LFQFP package, 160-MHz GPTW/HRPWM timing resolution (195 ps min), dual 12-bit ADC units with pseudo-differential PGA, CAN 2.0B interface, and IEC60730 safety support including CAC, CRCA, and register write protection.

Technical Context

The R5F566NDDGBG#20 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endian mode. It integrates three independent 12-bit A/D converter units (S12ADH) supporting simultaneous sampling across 30 channels, with dedicated sample-and-hold circuits and programmable gain amplifiers on six channels.

Its timer subsystem includes ten 32-bit GPTW channels with synchronous start/stop, dead-time control, and ELC-triggered operation, plus four HRPWM channels delivering 195 ps minimum timing resolution at 160 MHz - enabling precise gate drive for SiC/GaN-based motor inverters. The MCU supports full-speed USB 2.0 host/function/OTG and ISO 11898-1 CAN with 32 mailboxes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566NDDGBG#20?

The R5F566NDDGBG#20 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark performance per the official Renesas benchmark. This reflects deterministic real-time execution capability critical for motor control loops. The R5F566NDDGBG#20 uses the RXv3 CPU core with single-cycle instruction execution and integrated FPU, enabling fast mathematical operations required for field-oriented control algorithms.

Does the R5F566NDDGBG#20 support simultaneous sampling across all 30 ADC channels?

No - the R5F566NDDGBG#20 supports simultaneous sampling only within each of its three independent 12-bit A/D converter units (S12ADH): Unit 0 (8 channels), Unit 1 (8 channels), and Unit 2 (14 channels). Each unit has dedicated sample-and-hold circuits, allowing concurrent sampling across its assigned channels. Cross-unit synchronization requires ELC-triggered start signals, not true hardware simultaneity across all 30 channels.

What safety certifications and features does the R5F566NDDGBG#20 support for IEC60730 compliance?

The R5F566NDDGBG#20 includes multiple IEC60730 Class B–compliant features: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOC) for RAM testing, register write protection, and independent watchdog timer (IWDT). These are documented in the R01DS0315EJ0130 datasheet and enable self-test routines required for certification in industrial appliances and motor drives.

What is the resolution and timing capability of the HRPWM module in the R5F566NDDGBG#20?

The R5F566NDDGBG#20 integrates four HRPWM channels capable of controlling the rising/falling edges of GPTW-generated PWM waveforms with a minimum resolution of 195 ps when operating at 160 MHz. This enables precise dead-time insertion and edge alignment for SiC/GaN gate drivers. The HRPWM operates in conjunction with GPTW0–GPTW3 and requires no additional external timing ICs.

Which package variant corresponds to the R5F566NDDGBG#20, and what are its mechanical dimensions?

The R5F566NDDGBG#20 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size, 0.5 mm pin pitch, and exposed thermal pad. This package is rated for –40°C to +105°C operation (G-grade) and is compatible with standard reflow soldering profiles. Pin compatibility is maintained across all RX66T 144-pin variants.
