For engineers reviewing the R5F563NBCDLK#U0 datasheet, R5F563NBCDLK#U0 pinout, R5F563NBCDLK#U0 application, or R5F563NBCDLK#U0 equivalent, key selection criteria include Ethernet MAC support (vs. RX631), 100 MHz operation with 165 DMIPS, 1 MB flash/128 KB RAM configuration, TFLGA-145 package compatibility, and IEC60730 safety feature set including CRC, self-diagnostic A/D, and oscillation-stop detection.

Technical Context

The R5F563NBCDLK#U0 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code density. It integrates dedicated peripherals for industrial automation: Ethernet MAC (MII/RMII), three ISO11898-1 CAN modules (32 mailboxes each), and up to 13 SCI channels supporting asynchronous, SPI-like, and LIN modes.

Its clock system includes main crystal oscillator (4–16 MHz), PLL for 100 MHz ICLK, and independent 125-kHz LOCO for IWDT. Power management supports four low-power modes, RTC battery backup (VBATT = 2.3–3.6 V), and module stop functionality-all validated for -40°C to +85°C operation in the PTLG0145KA-A package.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F563NBCDLK#U0?

The R5F563NBCDLK#U0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS performance. This is achieved using the 32-bit RX CPU core with 5-stage pipeline and variable-length instruction set. The R5F563NBCDLK#U0 sustains this performance with zero wait-state access to its 1 MB on-chip flash memory, enabling deterministic real-time execution critical for industrial control loops.

Does the R5F563NBCDLK#U0 include an Ethernet MAC, and what interface standards does it support?

Yes, the R5F563NBCDLK#U0 includes a fully integrated Ethernet MAC supporting IEEE 802.3 10/100 Mbps operation in both full- and half-duplex modes. It implements MII (Media Independent Interface) and RMII (Reduced MII) as defined in IEEE 802.3u, and includes Magic Packet™ wake-on-LAN detection. The R5F563NBCDLK#U0 also integrates a dedicated EDMAC controller with 2 KB TX/RX FIFOs to offload packet processing from the CPU.

What safety and security features does the R5F563NBCDLK#U0 provide for IEC60730 compliance?

The R5F563NBCDLK#U0 provides hardware-level IEC60730 Class B support including oscillation-stoppage detection, hardware CRC calculator (with three polynomials), independent watchdog timer (IWDT) with dedicated 125-kHz oscillator, self-diagnostic function for the 10-bit A/D converter, and memory protection unit (MPU). These features are documented in the R01DS0098EJ0180 datasheet and eliminate the need for external safety monitors in certified designs.

What is the package type and pin count of the R5F563NBCDLK#U0, and how many I/O pins does it offer?

The R5F563NBCDLK#U0 uses the PTLG0145KA-A package: a 145-pin Thin Fine-Pitch Land Grid Array measuring 7 mm × 7 mm with 0.5 mm pitch. It provides 111 general-purpose I/O pins, including 18 pins with 5-V tolerance, programmable pull-up resistors on all I/Os, and open-drain capability. This matches the RX63N Group specification for 145-pin TFLGA variants as confirmed in Table 1.2 of the R01DS0098EJ0180 datasheet.

How much on-chip memory does the R5F563NBCDLK#U0 include, and what are the endurance specifications for data flash?

The R5F563NBCDLK#U0 integrates 1 MB of on-chip flash memory (zero wait states at 100 MHz), 128 KB of SRAM, and 32 KB of reprogrammable data flash. The data flash is rated for 100,000 program/erase cycles and supports background operation (BGO), allowing concurrent code execution and data logging. This configuration is explicitly listed for R5F563NBCDLK in Table 1.3 of the R01DS0098EJ0180 datasheet.
