FAQ

What is the maximum operating frequency and core performance of the R5F5630DCDFP#V0?

The R5F5630DCDFP#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance using its 32-bit RX CPU core. Its single-precision IEEE-754 floating-point unit enables efficient computation of motor control algorithms and sensor fusion tasks without external coprocessors. This performance level is sustained across the full -40°C to +85°C operating range.

Does the R5F5630DCDFP#V0 support CAN communication, and how many channels are implemented?

Yes, the R5F5630DCDFP#V0 integrates three fully compliant ISO 11898-1 CAN controllers (CAN0–CAN2), each supporting standard and extended frames with 32 configurable mailboxes. These channels operate independently with dedicated message RAM and filtering logic - enabling robust multi-node industrial network topologies without external CAN controllers. The R5F5630DCDFP#V0 requires external transceivers (e.g., TJA1042) for physical layer interfacing.

What are the memory resources available on the R5F5630DCDFP#V0?

The R5F5630DCDFP#V0 includes 1.5 Mbytes of on-chip flash memory (no wait states at 100 MHz), 128 Kbytes of SRAM (no wait states), and 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. The flash supports background programming/erasing, allowing firmware updates without halting real-time operations - a critical capability for industrial systems requiring zero-downtime maintenance.

How does the R5F5630DCDFP#V0 support functional safety standards like IEC60730?

The R5F5630DCDFP#V0 provides hardware-accelerated IEC60730 Class B compliance features including oscillation-stop detection for main/sub clocks, a dedicated independent watchdog timer (IWDT) with LOCO clock source, CRC calculation engine (X8/X16 polynomials), and self-diagnostic functions for the 10-bit A/D converter. These capabilities are documented in Renesas' Functional Safety Manual and eliminate the need for discrete safety monitors in certified appliance and industrial control designs.

What package type and pin count does the R5F5630DCDFP#V0 use, and is it compatible with standard PCB assembly?

The R5F5630DCDFP#V0 uses the PLQP0100KB-A package: a 100-pin LQFP with 14 × 14 mm body size and 0.5-mm pitch. It conforms to JEDEC MS-026AC standards and is compatible with automated SMT placement, reflow soldering (J-STD-020), and standard test fixtures. The exposed thermal pad supports enhanced heat dissipation in industrial enclosures without requiring custom footprints.
