Renesas R5F563TBBDFB#V1

Overview

R5F563TBBDFB#V1 from Renesas Electronics is a 100-MHz 32-bit RX CPU-based microcontroller designed for digital power supply control and motor inverter applications. It integrates dual 12-bit ADCs (with three sample-and-hold circuits, programmable gain amplifiers, and window comparators), one 10-bit 20-channel ADC, two 10-bit DACs, and hardware-accelerated digital power supply controller (DPC) logic. It operates across –40°C to +85°C and supports IEC60730 functional safety compliance.

For engineers reviewing the R5F563TBBDFB#V1 datasheet, R5F563TBBDFB#V1 pinout, R5F563TBBDFB#V1 application, or R5F563TBBDFB#V1 equivalent, key selection criteria include its 256 KB on-chip flash, 24 KB SRAM, CAN interface support, 144-pin LQFP package with 81 GPIOs, and integrated DPC unit optimized for real-time switched-mode power supply control.

Technical Context

The R5F563TBBDFB#V1 implements the RXv1 CPU core with IEEE-754 single-precision FPU, 165 DMIPS performance at 100 MHz, and memory protection unit (MPU). Its clock system combines external crystal/PLL (4–12.5 MHz input) with internal LOCO oscillators for system (ICLK), peripheral (PCLKA/B/C/D), and IWDT domains - enabling independent domain scaling up to 100 MHz for MTU3/GPT timers and ADCs.

It features dual ADC subsystems: S12ADB (two units × 4 channels, 1.0 µs conversion @ 50 MHz PCLKD) with simultaneous 7-channel sampling, and ADA (20 channels, 0.5 µs @ 100 MHz ADCLK); both support software, timer-triggered, and external-started conversions plus self-diagnostic functions required for IEC60730 Class B certification.

FAQ

What is the maximum operating frequency and CPU performance of the R5F563TBBDFB#V1?

The R5F563TBBDFB#V1 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS performance using the RXv1 32-bit CPU core. It includes a single-precision IEEE-754 floating-point unit, 32-bit multiplier (1-cycle execution), and divider (2-cycle execution), enabling efficient real-time control math. This performance level is sustained across its full operating temperature range of –40°C to +85°C.

Does the R5F563TBBDFB#V1 include CAN interface support, and what configuration does it use?

Yes, the R5F563TBBDFB#V1 includes a CAN 2.0B-compliant module (ISO 11898-1) with 32 configurable mailboxes and dedicated CAN_TX/CAN_RX pins. It supports both standard and extended frames, and the module is enabled in this part variant as confirmed by Renesas' official product list (R01DS0087EJ0220, Table 1.3). No external transceiver is integrated - an external CAN PHY is required for physical layer interfacing.

What ADC resources are available on the R5F563TBBDFB#V1, and how do they support motor control?

The R5F563TBBDFB#V1 integrates two independent ADC subsystems: S12ADB (two 4-channel 12-bit units with sample-and-hold, PGA, and window comparators) and ADA (20-channel 10-bit unit). Together they enable simultaneous sampling across 7 channels - essential for reconstructing three-phase motor currents. The 1.0 µs conversion time (S12ADB @ 50 MHz PCLKD) and hardware-triggered start ensure deterministic timing for field-oriented control loops.

Is the R5F563TBBDFB#V1 qualified for IEC60730 Class B compliance, and which features enable it?

Yes, the R5F563TBBDFB#V1 includes multiple hardware features explicitly designed for IEC60730 Class B compliance: oscillation-stop detection, CRC calculator (with three polynomials), self-diagnostic A/D converter, independent watchdog timer (IWDT) with dedicated LOCO, and frequency measurement circuit (CAC). These are documented in Renesas' RX63T datasheet (R01DS0087EJ0220) and eliminate the need for external safety monitors in certified designs.

What package type and pin count does the R5F563TBBDFB#V1 use, and are there thermal considerations?

The R5F563TBBDFB#V1 uses the PLQP0144KA-A package: a 144-pin LQFP with 20 mm × 20 mm body, 0.5 mm pitch, and exposed thermal pad. Its thermal resistance (θJA) is 28.5°C/W (JEDEC JESD51-7, 4-layer board). For continuous 100 MHz operation with active peripherals, Renesas recommends minimum 4-layer PCB routing with solid ground/power planes and thermal vias under the exposed pad to maintain junction temperature below 125°C.
