FAQ

What is the maximum operating frequency and core architecture of the R5F5630ADDLK#U0?

The R5F5630ADDLK#U0 operates at a maximum frequency of 100 MHz using the 32-bit RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instruction set. It delivers 165 DMIPS performance and includes a single-precision IEEE-754 floating-point unit (FPU) for hardware-accelerated math operations essential in motor control and signal processing applications. The R5F5630ADDLK#U0 uses this architecture to achieve deterministic real-time execution without software emulation overhead.

Which package type and pin count does the R5F5630ADDLK#U0 use?

The R5F5630ADDLK#U0 uses a 145-pin Thin Fine-Pitch Land Grid Array (TFLGA) package designated PTLG0145KA-A, measuring 7 × 7 mm with 0.5-mm pitch. This package supports 117 general-purpose I/O pins (including 53 with 5-V tolerance), dedicated debug interfaces (JTAG/FINE), and power/ground distribution optimized for high-frequency stability. The R5F5630ADDLK#U0's TFLGA footprint enables compact board layouts while maintaining thermal and signal integrity for industrial-grade operation.

Does the R5F5630ADDLK#U0 support functional safety standards like IEC60730?

Yes, the R5F5630ADDLK#U0 includes multiple hardware features certified for IEC60730 Class B compliance: oscillation-stop detection, dedicated independent watchdog timer (IWDT) with LOCO clock, CRC calculator supporting three polynomials, self-diagnostic function for the 10-bit A/D converter, and memory protection unit (MPU). These capabilities allow developers to implement safety-critical functions without external monitoring ICs. The R5F5630ADDLK#U0 leverages these integrated features to reduce certification effort and bill-of-materials cost in white goods and industrial controls.

What communication interfaces are integrated into the R5F5630ADDLK#U0?

The R5F5630ADDLK#U0 integrates USB 2.0 full-speed (12 Mbps), CAN × 3 (ISO11898-1 compliant, 32 mailboxes per channel), SCI × 13 (supporting asynchronous, SPI, I²C, LIN, and smart-card modes), RIIC × 4 (including one FM+ channel), RSPI × 3, and IEBus × 1. Its SCI modules support LIN frame format and average transfer rate clock input from TMR timers - critical for automotive diagnostics. The R5F5630ADDLK#U0 uses this comprehensive interface set to serve as a protocol-agnostic communication hub in multi-standard industrial networks.

How much on-chip memory does the R5F5630ADDLK#U0 provide, and what are its access characteristics?

The R5F5630ADDLK#U0 provides 768 Kbytes 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 write/erase cycles. Flash supports on-board programming via multiple methods and background operation (BGO) for data flash writes. The R5F5630ADDLK#U0's memory subsystem enables real-time code execution and data buffering without external memory latency penalties - essential for time-critical control loops and firmware-over-the-air (FOTA) updates.
