FAQ

What is the maximum operating frequency and core performance of the R5F563NECDLJ#U0?

The R5F563NECDLJ#U0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS using its 32-bit RX CPU core. Its single-precision IEEE-754 floating-point unit (FPU), two multiply-accumulate units, and 5-stage pipeline enable high-efficiency signal processing and real-time control tasks. This performance level is confirmed in Renesas document R01DS0098EJ0180 Rev.1.80, page 1.

Does the R5F563NECDLJ#U0 support Ethernet connectivity, and what interfaces are available?

Yes, the R5F563NECDLJ#U0 includes a fully integrated IEEE 802.3-compliant Ethernet MAC (ETHERC) supporting both MII and RMII physical layer interfaces at 10/100 Mbps. It also integrates a dedicated Ethernet DMA controller (EDMAC) with 2-Kbyte TX/RX FIFOs. This capability distinguishes the RX63N Group from the RX631 Group, which lacks Ethernet functionality entirely.

What are the memory resources available on the R5F563NECDLJ#U0?

The R5F563NECDLJ#U0 integrates 2 Mbytes of on-chip flash memory (zero-wait-state at 100 MHz), 128 Kbytes of SRAM (zero-wait-state), and 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. These resources are specified in Table 1.3 of R01DS0098EJ0180 Rev.1.80, confirming the part number R5F563NECDLJ maps to 2 Mbytes ROM, 128 Kbytes RAM, and 32 Kbytes E2 data flash.

Which package type and pin count does the R5F563NECDLJ#U0 use?

The R5F563NECDLJ#U0 uses a 100-pin TFLGA package (PTLG0100JA-A), measuring 7 × 7 mm with 0.65-mm pitch. It provides 78 general-purpose I/O pins, 17 of which are 5-V tolerant, and supports JTAG/FINE debugging interfaces. This package variant is explicitly listed in Table 1.3 of R01DS0098EJ0180 Rev.1.80 for the R5F563NECDLJ part number.

Does the R5F563NECDLJ#U0 include hardware security features for firmware protection?

Yes, the R5F563NECDLJ#U0 integrates a Data Encryption Unit (DEU) supporting AES-128/192/256 encryption and decryption in ECB and CBC modes. It also includes CRC calculation, oscillation-stop detection, and self-diagnostic functions for the A/D converter - all aligned with IEC60730 Class B safety requirements. These features are documented in Sections 1.1 and 1.2 of R01DS0098EJ0180 Rev.1.80.
