Renesas R5F562GAADFH#V1

Overview

R5F562GAADFH#V1 from Renesas Electronics is a 32-bit RX62G Group microcontroller designed for high-precision motor control and industrial inverter systems. It operates at up to 100 MHz, delivers 165 DMIPS, integrates dual 12-bit ADC units with sample-and-hold and programmable gain amplifiers, supports CAN 2.0B (32 mailboxes), and features eight 16-bit MTU3 timer channels for three-phase complementary PWM generation with hardware dead-time insertion.

For engineers reviewing the R5F562GAADFH#V1 datasheet, R5F562GAADFH#V1 pinout, R5F562GAADFH#V1 application, or R5F562GAADFH#V1 equivalent, this MCU is selected for IEC 60730-compliant real-time control where simultaneous 7-channel ADC sampling, robust independent watchdog (IWDT), CRC-based memory/data integrity checking, and deterministic 100-MHz PWM timing are required.

Technical Context

The R5F562GAADFH#V1 implements the 32-bit RX CPU core with IEEE-754 single-precision FPU, 64-bit accumulator, and CISC Harvard architecture with 5-stage pipeline. Its clock system supports PLL-based 100-MHz ICLK and configurable PCLK up to 50 MHz, enabling synchronized operation of CPU, MTU3, GPT, and peripheral modules.

It integrates three A/D converter units: two 12-bit S12ADA units (4 channels each, 1.0 µs conversion at 50 MHz ADCLK) with shared and per-unit sample-and-hold, programmable gain amplifiers (11-step scaling), and window comparators; plus one 10-bit ADA unit (12 channels). All ADC units support simultaneous 7-channel sampling and self-diagnostic functions per IEC 60730.

FAQ

What is the maximum operating frequency and performance rating of the R5F562GAADFH#V1?

The R5F562GAADFH#V1 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance. Its RX CPU core includes a single-precision IEEE-754 floating-point unit and a 64-bit accumulator optimized for motor control math. This performance level enables real-time execution of field-oriented control (FOC) algorithms with minimal interrupt latency, confirmed in Renesas' R01DS0096EJ0200 datasheet Section 1.1.

Does the R5F562GAADFH#V1 support CAN communication, and what configuration is required?

Yes, the R5F562GAADFH#V1 supports CAN 2.0B communication with 32 dedicated mailboxes and ISO 11898-1 compliance. It requires external CAN transceiver circuitry and proper termination on the CANH/CANL pins. The CAN module is enabled by default in the D version (R5F562GAADFH#V1), unlike non-CAN variants such as R5F562GADDFH#V1, as specified in Table 1.3 of the R01DS0096EJ0200 datasheet.

What ADC capabilities does the R5F562GAADFH#V1 provide for motor current sensing?

The R5F562GAADFH#V1 integrates two 12-bit S12ADA units (4 channels each) with three programmable gain amplifiers (2×–13.3×) and three window comparators per unit-ideal for shunt-based current sensing. It supports simultaneous sampling across seven channels with 1.0 µs conversion time at 50 MHz ADCLK, enabling precise phase-current reconstruction without CPU intervention, as detailed in Section 1.1 and Table 1.1 of R01DS0096EJ0200.

How does the R5F562GAADFH#V1 meet IEC 60730 safety requirements?

The R5F562GAADFH#V1 meets Class B IEC 60730 requirements through hardware-enforced safety mechanisms: an independent watchdog timer (IWDT) clocked by a dedicated 125-kHz LOCO, oscillation stop detection, CRC calculation unit for memory/data integrity, ADC self-diagnostic function, and PORT register monitoring. These features are explicitly validated in the datasheet's safety-related sections and block diagram (Figure 1.2).

What package and pin count does the R5F562GAADFH#V1 use, and is it pin-compatible with other RX62G variants?

The R5F562GAADFH#V1 uses the PLQP0112JA-A package: a 112-pin LQFP with 20 × 20 mm body and 0.65 mm pitch. It is pin-compatible with all other RX62G Group devices in the same 112-pin LQFP package (e.g., R5F562G7ADFH#V1, R5F562GAAGFH#V3), sharing identical pin functions and electrical characteristics per the "List of Pins and Pin Functions" in the R01DS0096EJ0200 datasheet.
