Renesas R5F563TBDDFB#V1

Overview

R5F563TBDDFB#V1 from Renesas is a 100-MHz 32-bit RX CPU-based microcontroller designed for digital power supply control and motor drive applications. It integrates dual 12-bit ADCs (with programmable gain amplifiers and window comparators), one 10-bit 20-channel ADC, two 10-bit DACs, CAN interface (not included in this variant), USB 2.0 full-speed, and hardware-accelerated digital power supply controller (DPC) logic. It operates across –40°C to +85°C and targets IEC60730-compliant industrial inverters.

For engineers reviewing the R5F563TBDDFB#V1 datasheet, R5F563TBDDFB#V1 pinout, R5F563TBDDFB#V1 application, or R5F563TBDDFB#V1 equivalent, key selection criteria include its 256 KB on-chip flash, 24 KB SRAM, 32 KB data flash, 100-MHz PWM timing resolution (312 ps delay control), and integrated DPC engine optimized for switched-mode power supply feedback loop computation.

Technical Context

The R5F563TBDDFB#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 supports external crystal or internal PLL (4–12.5 MHz input), with independent PCLKA (up to 100 MHz) for timers and PCLKD (up to 50 MHz) for 12-bit ADCs.

It features two independent A/D subsystems: S12ADB (12-bit × 8 channels, 1 µs conversion at 50 MHz ADCLK) and ADA (10-bit × 20 channels, 0.5 µs at 100 MHz ADCLK), both supporting software/external/timer-triggered conversion and self-diagnostic functions per IEC60730. The DPC unit performs fixed-point compensatory calculations using real-time ADC inputs.

FAQ

Does R5F563TBDDFB#V1 include a CAN interface?

No, R5F563TBDDFB#V1 does not include the CAN module. It belongs to the "DD" variant family (e.g., R5F563TBDDFB#V1, R5F563TCDDFB#V0), explicitly designated as CAN-free in Renesas' official product matrix. For CAN-enabled versions, refer to "TE", "TC", or "TB" parts with "AD" suffix (e.g., R5F563TEADFB#V1). The R5F563TBDDFB#V1 retains all other core peripherals including USB, SCI, RSPI, and dual ADC subsystems.

What is the maximum operating frequency and associated performance of R5F563TBDDFB#V1?

The R5F563TBDDFB#V1 operates at a maximum system clock frequency of 100 MHz. At this speed, it delivers 165 DMIPS of processing performance and supports 100-MHz operation for MTU3 and GPT timers, 50-MHz operation for 12-bit ADCs (S12ADB), and 100-MHz operation for the 10-bit ADC (ADA). Its RXv1 CPU core includes single-precision IEEE-754 FPU and hardware multiplier/divider for deterministic control loop execution.

How does the Digital Power Controller (DPC) in R5F563TBDDFB#V1 function in practice?

The DPC in R5F563TBDDFB#V1 is a dedicated 16-bit fixed-point calculation unit that executes compensator algorithms (e.g., PID, lead-lag) for switched-mode power supplies. It accepts real-time inputs from the 10-bit ADC, performs coefficient multiplication and accumulation, and outputs control values directly to PWM registers-bypassing CPU intervention. This ensures sub-microsecond loop latency and deterministic timing critical for stable SMPS operation.

What analog input capabilities does R5F563TBDDFB#V1 provide for motor control?

R5F563TBDDFB#V1 provides three independent A/D subsystems: two 12-bit S12ADB units (8 channels total, with 3× sample-and-hold, programmable gain amplifier, and window comparator) and one 10-bit ADA unit (20 channels, 0.5 µs conversion time). It supports simultaneous sampling across up to 7 channels-enabling synchronized current/voltage acquisition essential for field-oriented motor control and IEC60730 self-test routines.

Is R5F563TBDDFB#V1 qualified for IEC60730 Class B compliance?

Yes, R5F563TBDDFB#V1 includes multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection, independent watchdog timer (IWDT) with dedicated 125-kHz LOCO, CRC calculator, ADC self-diagnostic function, frequency measurement circuit (CAC), and register write protection. These are documented in the R01DS0087EJ0220 datasheet and form the basis for certified safety firmware implementations.
