For engineers reviewing the R5F565NEDGLK#20 datasheet, R5F565NEDGLK#20 pinout, R5F565NEDGLK#20 application, or R5F565NEDGLK#20 equivalent, key selection criteria include dual-bank flash for safe firmware updates, TSIP-based AES-128/192/256 encryption, 136 GPIOs with 5-V tolerance, RTC with battery backup, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.

Technical Context

The R5F565NEDGLK#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual-bank flash supporting background programming and bank-swapping during execution - critical for fail-safe OTA updates in field-deployed systems.

Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL to generate independent clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, GLCDC, DRW2D), and PCLKB up to 60 MHz for timers and ADC - enabling precise timing isolation across subsystems.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F565NEDGLK#20?

The R5F565NEDGLK#20 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance. This is achieved by the RXv2 CPU core with 5-stage pipeline and optimized instruction set. The R5F565NEDGLK#20 sustains this performance with zero-wait-state access to 640 KB SRAM and efficient cache-hit behavior in its 2 MB dual-bank flash - making it suitable for real-time industrial control loops and protocol stacks.

Does the R5F565NEDGLK#20 support secure boot and cryptographic acceleration?

Yes, the R5F565NEDGLK#20 includes Trusted Secure IP (TSIP) hardware that accelerates AES-128/192/256 encryption and decryption, along with a CRC calculator (CRCA) supporting multiple polynomials. It also provides register write protection, memory protection unit (MPU), and IEC60730-compliant safety features like oscillation-stop detection and self-diagnostic A/D - all essential for implementing secure boot and runtime integrity verification in the R5F565NEDGLK#20.

What display interfaces does the R5F565NEDGLK#20 integrate for HMI applications?

The R5F565NEDGLK#20 integrates a Graphic-LCD Controller (GLCDC) supporting up to 3 overlay planes and a 2D Drawing Engine (DRW2D) for hardware-accelerated vector graphics, bit blitting, and rotation. It supports common LCD data formats (32/16 bpp, CLUT), and connects directly to parallel RGB or CPU-interface displays. These capabilities eliminate external GPU requirements and enable responsive GUIs in resource-constrained HMIs built around the R5F565NEDGLK#20.

How many CAN channels and mailboxes does the R5F565NEDGLK#20 provide?

The R5F565NEDGLK#20 integrates two CAN modules compliant with ISO11898-1, each supporting 32 message mailboxes - totaling 64 configurable receive/transmit buffers. This enables robust multi-node communication in industrial automation networks, allowing simultaneous handling of high-priority control messages and lower-priority diagnostics traffic without CPU polling overhead in the R5F565NEDGLK#20.

What is the operating temperature range and package type of the R5F565NEDGLK#20?

The R5F565NEDGLK#20 is rated for –40°C to +105°C (G-version) and uses a 176-pin LFBGA package (PLQP0176KB-A, 24 × 24 mm, 0.5 mm pitch). This extended temperature grade and fine-pitch BGA make the R5F565NEDGLK#20 suitable for harsh industrial environments and high-density PCB layouts where thermal reliability and peripheral integration are critical.
