FAQ

What is the maximum operating frequency and CPU performance of the R5F5630ADDFB#V0?

The R5F5630ADDFB#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance using the RXv1 32-bit CPU core. Its single-precision IEEE-754 floating-point unit enables efficient execution of control algorithms without software emulation overhead, making it suitable for demanding real-time applications like motor control and digital power conversion where deterministic timing is critical. The R5F5630ADDFB#V0 achieves this performance with no wait states on its 768 Kbytes flash and 96 Kbytes SRAM.

Does the R5F5630ADDFB#V0 support functional safety standards such as IEC60730?

Yes, the R5F5630ADDFB#V0 includes multiple hardware features certified for IEC60730 Class B and Class C compliance, including oscillation-stop detection, built-in CRC calculator with three selectable polynomials, independent watchdog timer (IWDTA) with dedicated 125-kHz LOCO clock, and self-diagnostic functions for the 10-bit A/D converter. These capabilities reduce external component count and simplify safety certification for household appliances, medical devices, and industrial controls. The R5F5630ADDFB#V0 leverages these features to meet stringent runtime integrity requirements without requiring additional safety monitors.

What communication interfaces are integrated into the R5F5630ADDFB#V0?

The R5F5630ADDFB#V0 integrates USB 2.0 full-speed (12 Mbps), three CAN 2.0B channels (ISO11898-1 compliant, 32 mailboxes each), 13 serial communications interface (SCI) channels supporting UART, SPI, I²C, smart-card, and LIN protocols, four I²C bus interfaces (one FM+ capable at 1 Mbps), three RSPI channels, and one IEBus controller. This extensive connectivity enables heterogeneous network bridging - for example, using SCI for legacy RS-485 fieldbus, CAN for actuator coordination, and USB for configuration and diagnostics. All interfaces are accessible within the 144-pin LQFP footprint of the R5F5630ADDFB#V0.

What are the memory resources available on the R5F5630ADDFB#V0?

The R5F5630ADDFB#V0 provides 768 Kbytes of on-chip flash memory (executed at 100 MHz with zero wait states), 96 Kbytes of SRAM (also zero wait states), and 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. The flash supports background programming/erasing operations, allowing firmware updates without halting application execution. The memory map is linear (4 Gbyte address space), and the MPU enforces memory protection for secure multitasking. These resources are fixed for the R5F5630ADDFB#V0 and match the "A" ROM capacity designation in Renesas' part numbering scheme.

What package type and pin count does the R5F5630ADDFB#V0 use?

The R5F5630ADDFB#V0 uses the PLQP0144KA-A package: a 144-pin Low-profile Quad Flat Package measuring 20 mm × 20 mm with 0.5 mm lead pitch and an exposed thermal pad. This package supports 117 general-purpose I/O pins (5-V tolerant, open-drain capable), 148 total I/O signals including dedicated debug and power pins, and 16 external interrupt inputs (IRQ0–IRQ15). The "FB" suffix in R5F5630ADDFB#V0 explicitly denotes the 144-pin LQFP variant, distinguishing it from 100-pin (FP), 176-pin (FC), or BGA (BG) versions of the RX630 Group.
