Renesas R5F5630BDDFC#V0

Overview

R5F5630BDDFC#V0 from Renesas is a 100-MHz 32-bit RX630 Group MCU with on-chip FPU, 1 Mbyte flash, 96 Kbytes SRAM, and 32 Kbytes data flash. It integrates USB 2.0 full-speed, CAN (3 channels), 12-bit/10-bit A/D converters (21+8 ch), dual 10-bit D/A, RTC, and 148 GPIO pins. Used in industrial motor control, PLCs, and embedded HMI systems requiring deterministic real-time response and IEC60730 compliance.

For engineers reviewing the R5F5630BDDFC#V0 datasheet, R5F5630BDDFC#V0 pinout, R5F5630BDDFC#V0 application, or R5F5630BDDFC#V0 equivalent, key selection criteria include its LQFP-176 package, -40 to +85°C operating range, 100 MHz CPU clock with 165 DMIPS, integrated CAN/USB/IEBus interfaces, and support for background programming of data flash.

Technical Context

The R5F5630BDDFC#V0 implements the RX CPU core with CISC Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point math for motion control algorithms. Its memory subsystem includes zero-wait-state 100-MHz flash and SRAM, plus background-programmable 32-Kbyte E² data flash supporting 100,000 erase/write cycles.

Peripherals are clocked independently: ICLK up to 100 MHz (CPU), PCLK up to 50 MHz (peripherals), FCLK up to 50 MHz (FlashIF), and BCLK up to 50 MHz (external bus). The device supports four low-power modes, RTC battery backup (VBATT ≥ 2.3 V), and hardware CRC acceleration for safety-critical firmware integrity checks.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F5630BDDFC#V0?

The R5F5630BDDFC#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS performance. This is achieved through its optimized RX CPU core with 5-stage pipeline and ultra-compact variable-length instruction set. The R5F5630BDDFC#V0 maintains this performance with zero-wait-state access to both flash and SRAM, enabling deterministic real-time execution critical for industrial control loops.

Does the R5F5630BDDFC#V0 support IEC60730 Class B compliance out of the box?

Yes, the R5F5630BDDFC#V0 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, hardware CRC calculator, self-diagnostic function for the 10-bit A/D converter, independent watchdog timer (IWDT) with dedicated clock source, and frequency measurement capability for multiple on-chip oscillators. These are documented in the R01DS0060EJ0160 datasheet and require no external components to implement basic Class B checks.

What package type and dimensions does the R5F5630BDDFC#V0 use?

The R5F5630BDDFC#V0 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 mm × 24 mm body size, 0.5 mm pin pitch, and internal thermal pad. This package is RoHS-compliant and designed for standard surface-mount reflow assembly. Pin compatibility is maintained across all RX630 Group devices using this package variant, enabling scalable design reuse.

How many CAN channels does the R5F5630BDDFC#V0 support, and what protocol versions are implemented?

The R5F5630BDDFC#V0 supports three fully independent CAN channels compliant with ISO11898-1, handling both standard (11-bit) and extended (29-bit) frame formats. Each channel includes 32 dedicated mailboxes with programmable acceptance filtering, FIFO mode, and automatic retransmission. The CAN module operates up to 1 Mbps and integrates bus-off recovery logic - confirmed in Table 1.2 of the R01DS0060EJ0160 datasheet for the 176-pin package variant.

Can the R5F5630BDDFC#V0 execute code while programming its data flash memory?

Yes, the R5F5630BDDFC#V0 supports background programming (BGO) of its 32-Kbyte data flash memory. This allows firmware to initiate erase/write operations on data flash sectors while simultaneously executing application code from main flash or SRAM. BGO is managed via dedicated control registers and interrupt flags, enabling seamless field updates and parameter storage without system interruption - a feature explicitly specified in the "On-chip data flash memory" section of the datasheet.
