Renesas R5F5630BCDFC#V0

Overview

R5F5630BCDFC#V0 from Renesas is a 100-MHz 32-bit RX CPU-based microcontroller with single-precision IEEE-754 FPU, 1 Mbyte on-chip flash, 96 Kbytes SRAM, and integrated USB 2.0 full-speed, CAN, 12-bit A/D (21 ch), 10-bit D/A (2 ch), RTC, and temperature sensor - deployed in industrial motor control and factory automation systems requiring deterministic real-time response.

For engineers reviewing the R5F5630BCDFC#V0 datasheet, R5F5630BCDFC#V0 pinout, R5F5630BCDFC#V0 application, or R5F5630BCDFC#V0 equivalent, key selection criteria include its LQFP-176 package, 100 MHz operation with 165 DMIPS, 4-channel DMAC, 3-channel CAN, and IEC60730-compliant self-diagnostic features for functional safety-critical firmware.

Technical Context

The R5F5630BCDFC#V0 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) for secure embedded execution. It supports dual-clock domains: ICLK up to 100 MHz for CPU/core logic, and PCLK up to 50 MHz for peripherals including MTU2, TPU, and A/D converters.

Its timing subsystem integrates three independent clock sources - main crystal oscillator (4–16 MHz), sub-clock (32 kHz), and on-chip HOCO/LOCO oscillators - enabling precise RTC operation with battery backup (VBATT ≥ 2.3 V) and independent watchdog timer (IWDT) driven by dedicated 125-kHz oscillator.

FAQ

What is the maximum operating frequency and CPU performance of the R5F5630BCDFC#V0?

The R5F5630BCDFC#V0 operates at a maximum system clock frequency of 100 MHz, delivering 165 DMIPS of processing performance. Its RX CPU core features a 5-stage pipeline, single-precision IEEE-754 FPU, and ultra-compact variable-length instruction set - enabling deterministic real-time execution for motor control and industrial automation tasks. The R5F5630BCDFC#V0 achieves this performance with zero-wait-state access to both 1 Mbyte flash and 96 Kbytes SRAM.

Does the R5F5630BCDFC#V0 include CAN interface support?

No, the R5F5630BCDFC#V0 does not include CAN functionality. The 'C' in the part number suffix indicates CAN omission (per Renesas naming convention: 'C' = CAN excluded, 'D' = CAN included). This variant retains all other peripherals - USB 2.0, 3-channel RSPI, 4-channel RIIC, 13-channel SCI, and 3-channel IEBus - making it ideal for applications requiring high-speed serial connectivity without CAN bus dependency.

What package type and pin count does the R5F5630BCDFC#V0 use?

The R5F5630BCDFC#V0 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 × 24 mm body size and 0.5-mm pin pitch. It provides 148 general-purpose I/O pins with 5-V tolerance, internal pull-up resistors, and open-drain capability - supporting direct interfacing with legacy 5-V logic and industrial sensors without level shifters.

How does the R5F5630BCDFC#V0 support functional safety standards like IEC60730?

The R5F5630BCDFC#V0 integrates multiple hardware features for IEC60730 Class B compliance: oscillation-stop detection for main/sub clocks, dedicated independent watchdog timer (IWDT) with 125-kHz on-chip oscillator, CRC calculator with three selectable polynomials, self-diagnostic function for the 10-bit A/D converter, and memory protection unit (MPU) for runtime code/data integrity enforcement - all documented in the RX630 Group Hardware Manual.

What are the supported clock sources and low-power modes for the R5F5630BCDFC#V0?

The R5F5630BCDFC#V0 supports multiple clock sources: external 4–16 MHz crystal (XTAL/EXTAL), 32.768 kHz sub-clock (XCOUT/XCIN), and on-chip HOCO (50 MHz) and LOCO (125 kHz) oscillators. It implements four low-power modes - Sleep, All-module clock stop, Software standby, and Deep software standby - with RTC and data retention enabled even in deep standby using VBATT (2.3–3.6 V).
