For engineers reviewing the R5F5630DCDFC#V0 datasheet, R5F5630DCDFC#V0 pinout, R5F5630DCDFC#V0 application, or R5F5630DCDFC#V0 equivalent, this page delivers verified package mapping (PLQP0176KB-A, 176-pin LQFP), confirmed peripheral channel counts (CAN×3, SCI×12+1, RIIC×4, RSPI×3), power supply specs (2.7–3.6 V), operating temperature (−40 to +85°C), and validated alternative part options for migration or sourcing continuity.

Technical Context

The R5F5630DCDFC#V0 implements the RX630 Group's CISC Harvard architecture with 5-stage pipeline, supporting 165 DMIPS at 100 MHz and variable-length instructions for ultra-compact code density. It integrates dual clock domains: system clock (ICLK) up to 100 MHz for CPU/core logic, and peripheral module clock (PCLK) up to 50 MHz for timers, ADCs, and communication peripherals.

Its memory subsystem includes no-wait-state 100-MHz flash, 128-Kbyte SRAM with deep software standby backup, and 32-Kbyte data flash rated for 100,000 erase/program cycles. The MCU supports IEC60730-compliant features including oscillation-stop detection, CRC calculator (X8/X16 polynomials), self-diagnostic A/D, and independent watchdog timer (IWDT) driven by dedicated 125-kHz LOCO.

It includes a single-precision IEEE-754 floating-point unit, 32-bit multiplier (1-cycle execution), and divider (2-cycle execution), enabling efficient math-intensive tasks such as motor control algorithms and sensor fusion without external coprocessors.

Does the R5F5630DCDFC#V0 support IEC60730 functional safety compliance?

Yes, the R5F5630DCDFC#V0 includes multiple hardware features required for Class B IEC60730 compliance: oscillation-stop detection, frequency measurement (MCK), CRC calculator with three selectable polynomials, independent watchdog timer (IWDT) with dedicated LOCO clock, and self-diagnostic capability for the 10-bit A/D converter-all documented in the RX630 Group hardware manual and supported by Renesas safety libraries.

What package type and pin count does the R5F5630DCDFC#V0 use?

The R5F5630DCDFC#V0 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 mm × 24 mm body size and 0.5-mm pitch. It provides 148 general-purpose I/O pins, of which 54 are 5-V tolerant, and supports external bus expansion across eight chip-select areas with configurable 8/16/32-bit data width per area.
