Renesas R5F562T6DDFF#H3

Overview

R5F562T6DDFF#H3 from Renesas Electronics is a 32-bit RX CPU-based microcontroller designed for motor control and industrial real-time applications. 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 three-phase complementary PWM via MTU3, and features CAN interface (not supported in this variant). It targets inverter-driven AC motor control systems requiring precise timing, analog sensing, and functional safety compliance.

For engineers reviewing the R5F562T6DDFF#H3 datasheet, R5F562T6DDFF#H3 pinout, R5F562T6DDFF#H3 application, or R5F562T6DDFF#H3 equivalent, key selection criteria include its 64-KB flash / 8-KB SRAM configuration, 80-pin LQFP package (PLQP0080JA-A), 5-V operation, -40°C to +85°C temperature range, and absence of CAN - making it suitable for cost-optimized, non-automotive motor drive designs where IEC 60730 self-test capability and high-resolution PWM timing are critical.

Technical Context

The R5F562T6DDFF#H3 implements the RX62T Group architecture with a CISC Harvard 5-stage pipeline core supporting IEEE-754 single-precision FPU and 64-bit accumulator operations. Its clock system uses an external crystal or internal PLL to generate ICLK up to 100 MHz and PCLK up to 50 MHz, with independent division/multiplication paths for system and peripheral domains.

It integrates three A/D converter units: two 12-bit S12ADA units (4 channels each, simultaneous 7-channel sampling) and one 10-bit ADA unit (12 channels), all supporting self-diagnosis per IEC 60730. The MTU3 timer provides eight 16-bit channels with three-phase complementary PWM output, dead-time control, and hardware-triggered A/D conversion - essential for closed-loop motor control without CPU intervention.

FAQ

What is the maximum operating frequency and performance rating of the R5F562T6DDFF#H3?

The R5F562T6DDFF#H3 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 jitter, as confirmed in Renesas' R01DS0096EJ0200 datasheet Section 1.1.

Does the R5F562T6DDFF#H3 support CAN communication?

No, the R5F562T6DDFF#H3 does not support CAN communication. The "D" in its part number suffix indicates "5-V version, CAN not supported", per Figure 1.1 and Table 1.3 of the R01DS0096EJ0200 datasheet. It retains three SCIs, one I²C, one RSPI, and one LIN master interface - making it suitable for non-automotive industrial networks where CAN is unnecessary.

What analog capabilities does the R5F562T6DDFF#H3 provide for motor current sensing?

The R5F562T6DDFF#H3 integrates two 12-bit S12ADA units (4 channels each) and one 10-bit ADA unit (12 channels), with simultaneous 7-channel sampling capability. Each 12-bit unit includes three programmable gain amplifier channels (2×–13.3×), sample-and-hold circuits, and window comparators - enabling direct shunt-based current sensing with hardware-triggered acquisition synchronized to MTU3 PWM edges.

Which package and pin count does the R5F562T6DDFF#H3 use?

The R5F562T6DDFF#H3 uses an 80-pin LQFP package designated PLQP0080JA-A: 14×14 mm body size with 0.65 mm pitch, RoHS-compliant and lead-free. This matches the "FF" suffix in the part number per Figure 1.1 of the R01DS0096EJ0200 datasheet and supports 44 I/O pins and 13 input-only pins as specified in Table 1.2.

How does the R5F562T6DDFF#H3 support IEC 60730 functional safety compliance?

The R5F562T6DDFF#H3 supports IEC 60730 Class B compliance through hardware features including self-diagnostic ADC, CRC calculator for memory/data integrity checking, oscillation stop detection for the main clock, independent watchdog timer (IWDT) with dedicated LOCO clock, and PORT register monitoring. These are documented in Sections 1.1 and 1.2 of R01DS0096EJ0200 and eliminate need for external safety monitors in many industrial applications.
