For engineers reviewing the R5F5630ACDLC#U0 datasheet, R5F5630ACDLC#U0 pinout, R5F5630ACDLC#U0 application, or R5F5630ACDLC#U0 equivalent, key selection criteria include its TFLGA-177 package, -40°C to +85°C operating range, 100 MHz real-time deterministic execution, integrated CAN/USB dual-protocol support, and IEC60730-compliant safety features including CRC, IWDT, and A/D self-diagnosis.

Technical Context

The R5F5630ACDLC#U0 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, enabling precise timing isolation between computation and I/O subsystems.

Its peripheral set includes three independent CAN controllers (ISO 11898-1 compliant, 32 mailboxes each), a USB 2.0 device controller with 2 KB on-chip buffer, and dual A/D converters - one 12-bit (21-channel, 1 µs conversion at 50 MHz PCLK) and one 10-bit (8-channel) - both supporting hardware-triggered sampling via MTU2/TPU timers or external pins.

FAQ

What is the maximum operating frequency and CPU performance of the R5F5630ACDLC#U0?

The R5F5630ACDLC#U0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance using its 32-bit RX CPU core. It includes a single-precision IEEE-754 floating-point unit (FPU) for hardware-accelerated math operations, making it suitable for real-time control algorithms such as motor FOC or digital power supply regulation. The R5F5630ACDLC#U0 achieves deterministic instruction execution with a 5-stage pipeline and ultra-compact variable-length instruction set.

Which package type and pin count does the R5F5630ACDLC#U0 use?

The R5F5630ACDLC#U0 uses the PTLG0177KA-A package: a 177-pin Thin Fine-Pitch Land Grid Array (TFLGA) with 8 mm × 8 mm body size and 0.5 mm pitch. This package supports high I/O density (148 general-purpose pins), 5-V tolerant inputs on selected pins, and low-inductance grounding for noise-sensitive analog/mixed-signal operation. Its compact footprint and thermal characteristics suit space-constrained industrial modules.

Does the R5F5630ACDLC#U0 support IEC60730 functional safety requirements?

Yes, the R5F5630ACDLC#U0 includes multiple hardware features to support IEC60730 Class B compliance, including oscillation-stop detection, dedicated independent watchdog timer (IWDT) with isolated clock source, CRC calculator with configurable polynomials, and self-diagnostic capability for the 10-bit A/D converter. These features are documented in the RX630 Group hardware manual and enable certified safety firmware implementations without external supervision circuitry.

How many CAN interfaces does the R5F5630ACDLC#U0 integrate, and what standards do they support?

The R5F5630ACDLC#U0 integrates three fully independent CAN modules compliant with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) frame formats. Each channel provides 32 dedicated mailboxes for flexible message filtering and prioritization. These CAN interfaces operate concurrently and can be configured for different bit rates, enabling multi-network topology support - for example, one for motor control, one for diagnostics, and one for HMI communication - all within a single R5F5630ACDLC#U0 device.

What are the memory resources available on the R5F5630ACDLC#U0?

The R5F5630ACDLC#U0 includes 768 KB of on-chip main flash memory (accessible at 100 MHz with zero wait states), 96 KB of high-speed SRAM (also zero-wait), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. The flash supports background programming/erasing (BGO), allowing code execution during non-volatile updates. All memory blocks are protected by the integrated memory protection unit (MPU) to enforce privilege levels and prevent unintended access.
