For engineers reviewing the R5F56517FGLJ#20 datasheet, R5F56517FGLJ#20 pinout, R5F56517FGLJ#20 application, or R5F56517FGLJ#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual-bank flash for safe OTA updates, integrated GLCDC + DRW2D for 2D GUI acceleration, and IEC60730-compliant safety features including CRC calculator, IWDT with window function, and register write protection.
Technical Context
The R5F56517FGLJ#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a dedicated 120-MHz system clock (ICLK) and independent peripheral clocks (PCLKA up to 120 MHz for ETHERC/DRW2D/GLCDC; PCLKB up to 60 MHz for timers/A/D).
Its memory subsystem includes dual-bank flash supporting background programming and bank-swapping at reset, 32 KB data flash rated for 100,000 erase/write cycles, and 8 KB standby RAM backed by VBATT. Safety-critical functions are enabled via MPU (8 regions), Trusted Memory (TM) for code protection, and CRCA supporting configurable 8-/32-bit CRC polynomials.

Does the R5F56517FGLJ#20 support secure firmware updates and cryptographic operations?
Yes, the R5F56517FGLJ#20 integrates hardware-accelerated AES-128/192/256 encryption, Trusted Secure IP (TSIP) for key management, and dual-bank code flash memory. These features enable authenticated, encrypted, and atomic firmware updates - where one bank runs the active image while the other is programmed and verified - meeting IEC60730 Class B requirements for safe field upgrades without runtime interruption.
What display and graphics capabilities does the R5F56517FGLJ#20 provide?
The R5F56517FGLJ#20 includes a Graphic-LCD Controller (GLCDC) supporting 24-bit RGB parallel output up to WXGA resolution and a 2D Drawing Engine (DRW2D) capable of vector drawing (lines, triangles, circles), bit-blitting with rotation/stretching, and 3-layer plane compositing. These peripherals offload GUI rendering from the CPU, reduce external memory bandwidth, and enable responsive touch-based HMIs in resource-constrained industrial panels.
How many CAN interfaces does the R5F56517FGLJ#20 include, and what is their compliance level?
The R5F56517FGLJ#20 integrates two fully independent CAN 2.0B modules compliant with ISO 11898-1, each supporting standard and extended frames with 32 configurable mailboxes. Each channel provides dedicated TX/RX pins, error counters, and loopback/self-test modes. The CAN modules operate synchronously with PCLKB (up to 60 MHz) and support bit rates up to 1 Mbps, making them suitable for deterministic industrial networking and automotive subsystem communication.
What is the package type and thermal specification of the R5F56517FGLJ#20?
The R5F56517FGLJ#20 uses a PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm pitch. It is rated for industrial temperature operation from –40°C to +105°C (G-version), qualified per JEDEC J-STD-020 moisture sensitivity level (MSL) 3, and RoHS-compliant.
