The R5F565N4EGLK#20 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instruction set. It delivers 240 DMIPS performance and includes single-precision IEEE-754 floating-point unit, on-chip multiplier (1-cycle), and divider (2-cycle). This architecture enables high code density and deterministic real-time execution critical for industrial control tasks in the R5F565N4EGLK#20.

Does the R5F565N4EGLK#20 support secure boot and cryptographic operations?

Yes, the R5F565N4EGLK#20 integrates Trusted Secure IP (TSIP) hardware acceleration for AES-128/192/256 encryption/decryption, secure key storage, and random number generation. It also supports Trusted Memory (TM) to protect code flash regions from unauthorized read access. These features-combined with CRC calculator (CRCA), independent watchdog timer (IWDT) with windowing, and register write protection-enable certified secure boot and firmware update workflows compliant with IEC60730 Class B requirements for the R5F565N4EGLK#20.

What display interfaces and graphics capabilities does the R5F565N4EGLK#20 provide?

The R5F565N4EGLK#20 includes a full-featured Graphic-LCD Controller (GLCDC) supporting 24-bit RGB parallel output (GLCD_D0–D23) and a dedicated 2D Drawing Engine (DRW2D) for hardware-accelerated vector graphics (lines, circles), bit blitting, rotation, and scaling. It supports multiple pixel formats (RGB565, RGB666, CLUT), three overlay planes, and direct frame buffer access. These capabilities eliminate the need for external graphics controllers in HMI applications built around the R5F565N4EGLK#20.

How many CAN interfaces does the R5F565N4EGLK#20 support, and what is their compliance level?

The R5F565N4EGLK#20 integrates two fully independent CAN modules compliant with ISO 11898-1 (CAN 2.0B), each supporting standard and extended frames with 32 configurable mailboxes. Both CAN channels support bit rates up to 1 Mbps, programmable sample points, loopback mode for self-test, and error counters with interrupt reporting. This dual-CAN capability enables robust fieldbus communication in industrial automation systems using the R5F565N4EGLK#20 as the central controller.

What is the package type and pin count of the R5F565N4EGLK#20?

The R5F565N4EGLK#20 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 0.65 mm height.
