FAQ

What is the maximum operating frequency and core architecture of the R5F5630BCDLC#U0?

The R5F5630BCDLC#U0 operates at a maximum frequency of 100 MHz using the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions. It delivers 165 DMIPS performance and includes a single-precision IEEE-754 floating-point unit (FPU) for deterministic real-time math operations essential in motor control and sensor processing applications. The R5F5630BCDLC#U0 core supports memory protection unit (MPU) and fast interrupt response.

Does the R5F5630BCDLC#U0 support functional safety standards like IEC60730?

Yes, the R5F5630BCDLC#U0 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stop detection, dedicated independent watchdog timer (IWDT) with 125-kHz on-chip oscillator, CRC calculator with three selectable polynomials, self-diagnostic function for the 10-bit A/D converter, and clock frequency measurement capability. These features reduce software validation burden and support systematic safety measures in household and industrial appliances. The R5F5630BCDLC#U0 documentation explicitly lists these functions as IEC60730-enabling.

What package type and pin count does the R5F5630BCDLC#U0 use?

The R5F5630BCDLC#U0 uses the PTLG0177KA-A package: a 177-pin Thin Fine-Pitch Land Grid Array (TFLGA) with 8 mm × 8 mm body size, 0.5 mm pitch, and 0.75 mm height. It provides 148 general-purpose I/O pins (54 of which are 5-V tolerant), along with dedicated power, clock, reset, and debug interface pins. This compact, high-density package supports automated SMT assembly and efficient thermal dissipation in space-constrained industrial modules.

How much on-chip memory does the R5F5630BCDLC#U0 integrate, and what are its access characteristics?

The R5F5630BCDLC#U0 integrates 1 Mbyte of on-chip flash memory (accessible at 100 MHz with zero wait states), 96 Kbytes of SRAM (also zero-wait at 100 MHz), and 32 Kbytes of data flash rated for 100,000 erase/write cycles. Flash supports on-board programming via multiple interfaces and background operation for data flash writes. The R5F5630BCDLC#U0 memory map includes 4-Gbyte linear address space, MPU enforcement, and configurable endian mode for data transfers.

Which communication interfaces are available on the R5F5630BCDLC#U0, and how many instances of each?

The R5F5630BCDLC#U0 provides USB 2.0 full-speed (1 port), CAN (3 channels, 32 mailboxes each), serial communications interfaces (13 total: 12 SCIc + 1 SCId), I2C bus interfaces (4 channels, one FM+), RSPI (3 channels), and IEBus (1 channel). All interfaces support independent clocking, DMA/DTC transfer, and flexible configuration (e.g., SCI supports asynchronous, SPI, I2C, and LIN modes). The R5F5630BCDLC#U0 datasheet confirms these counts apply to the TFLGA-177 package variant.
