Overview

R5F562GAAGFH#V3 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 256 KB on-chip flash, 16 KB SRAM, and 32 KB data flash - all qualified for −40°C to +105°C operation.

For engineers reviewing the R5F562GAAGFH#V3 datasheet, R5F562GAAGFH#V3 pinout, R5F562GAAGFH#V3 application, or R5F562GAAGFH#V3 equivalent, key selection criteria include its 100-MHz MTU3/GPT complementary PWM capability with hardware dead-time generation, simultaneous 7-channel ADC sampling across three A/D units, IEC 60730-compliant self-diagnostic features (CRC, IWDT, analog self-test), and support for 112-pin LQFP package with 61 I/O pins and 21 input-only pins.

Technical Context

The R5F562GAAGFH#V3 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, IEEE-754 single-precision FPU, and memory protection unit (MPU). Its clock system combines an external crystal oscillator or internal PLL for 8–100 MHz ICLK, with independent PCLK division (8–50 MHz) for peripherals.

It integrates three A/D converter units: two 12-bit S12ADA units (4 channels each, shared and per-unit sample-and-hold, 3-channel programmable gain amplifiers, window comparators) and one 10-bit ADA unit (12 channels), all supporting simultaneous 7-channel sampling triggered by MTU3 or GPT. The CAN module is enabled and compliant with ISO 11898-1.

FAQ

What is the maximum operating frequency and performance rating of the R5F562GAAGFH#V3?

The R5F562GAAGFH#V3 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance. This is achieved using the 32-bit RX CPU core with a 5-stage pipeline, single-cycle 32×32-bit multiplication, and integrated IEEE-754 floating-point unit - enabling real-time execution of complex motor control algorithms without external co-processors. The R5F562GAAGFH#V3 sustains this performance across its full −40°C to +105°C operating range.

Does the R5F562GAAGFH#V3 support IEC 60730 Class B functional safety requirements?

Yes, the R5F562GAAGFH#V3 includes multiple hardware features certified for IEC 60730 Class B compliance: an independent watchdog timer (IWDT) clocked by a dedicated 125-kHz LOCO oscillator, cyclic redundancy check (CRC) calculation unit for memory and data integrity, analog self-diagnostic capability in both 12-bit ADC units, and oscillation stoppage detection for the main crystal oscillator. These features are implemented in silicon and require no software overhead to maintain safety integrity in the R5F562GAAGFH#V3.

What ADC resources does the R5F562GAAGFH#V3 provide for motor current sensing?

The R5F562GAAGFH#V3 provides three coordinated A/D converter units: two 12-bit S12ADA units (4 channels each) with per-unit sample-and-hold circuits, 3-channel programmable gain amplifiers (11 gain steps), and window comparators; plus one 10-bit ADA unit (12 channels). All three units support simultaneous 7-channel sampling - essential for capturing phase currents and DC-link voltage without timing skew during FOC execution in the R5F562GAAGFH#V3.

Which PWM peripherals in the R5F562GAAGFH#V3 support hardware dead-time insertion?

The R5F562GAAGFH#V3 supports hardware dead-time insertion exclusively in the MTU3 (Multi-function Timer Pulse Unit 3) - used for its two three-phase complementary PWM output channels. Dead-time is automatically applied and adjustable in the R5F562GAAGFH#V3 without CPU intervention, preventing shoot-through in inverter bridge drivers. The GPTa unit supports complementary PWM but does not implement hardware dead-time; it relies on software or external logic for timing safety.

Is CAN functionality enabled in the R5F562GAAGFH#V3, and what protocol version does it support?

Yes, CAN functionality is fully enabled in the R5F562GAAGFH#V3. It integrates a CAN module compliant with ISO 11898-1, supporting CAN 2.0B protocol with 32 configurable mailboxes, bit rates up to 1 Mbit/s, and built-in message filtering and FIFO buffering. This capability is confirmed in the device's product listing (Table 1.3) and functional overview (Section 1.2), making the R5F562GAAGFH#V3 suitable for industrial networked motor control systems requiring robust diagnostics and interoperability.
