For engineers reviewing the R5F56519FGLJ#20 datasheet, R5F56519FGLJ#20 pinout, R5F56519FGLJ#20 application, or R5F56519FGLJ#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual-bank flash for safe OTA updates, integrated GLCDC + DRW2D for embedded GUIs, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.

Technical Context

The R5F56519FGLJ#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual-clock domain operation: ICLK up to 120 MHz for CPU/core logic, and PCLKA up to 120 MHz for high-speed peripherals (ETHERC, EDMAC, AES, GLCDC), while PCLKB runs up to 60 MHz for timers, ADC, and communication modules.

Its memory subsystem includes 2 MB dual-bank code flash (enabling background programming and bank-swapping during execution), 32 KB data flash (100,000 erase/write cycles), 640 KB SRAM (256 KB main + 384 KB expansion), and 8 KB standby RAM backed by VBATT. Peripheral integration follows a modular, event-driven architecture via the Event Link Controller (ELC), allowing timer-triggered ADC conversions, PWM-to-PPG chaining, and interrupt-free peripheral coordination.

FAQ

What is the maximum operating frequency and CPU performance of the R5F56519FGLJ#20?

The R5F56519FGLJ#20 operates at a maximum system clock frequency of 120 MHz and delivers 240 DMIPS of processing performance using the RXv2 CPU core. Its single-precision IEEE-754 floating-point unit enables efficient math-intensive tasks such as sensor fusion and real-time filtering without software emulation overhead. The R5F56519FGLJ#20 achieves this performance with low power consumption - approximately 0.19 mA/MHz under typical peripheral load - making it suitable for thermally constrained industrial enclosures.

Does the R5F56519FGLJ#20 support secure over-the-air (OTA) firmware updates?

Yes, the R5F56519FGLJ#20 supports robust OTA firmware updates via its dual-bank code flash architecture. One bank can execute active firmware while the other is programmed in background, and the startup bank can be swapped atomically via the FASR register. Combined with hardware AES encryption and Trusted Secure IP (TSIP), the R5F56519FGLJ#20 enables authenticated, encrypted firmware images that prevent unauthorized modification or rollback. This capability is certified for IEC60730 Class B compliance.

What display interfaces and graphics acceleration does the R5F56519FGLJ#20 provide?

The R5F56519FGLJ#20 integrates a Graphic-LCD Controller (GLCDC) supporting RGB/TFT panels up to WXGA resolution and a dedicated 2D Drawing Engine (DRW2D) with hardware-accelerated bit blitting, rotation, stretching, and vector primitives. These peripherals operate independently of the CPU, reducing rendering latency and freeing the RXv2 core for application logic. The R5F56519FGLJ#20 uses dedicated SRAM regions for framebuffers and textures, ensuring deterministic display refresh even under heavy CPU load.

How many CAN channels does the R5F56519FGLJ#20 support, and what protocol versions are compliant?

The R5F56519FGLJ#20 integrates two independent CAN modules compliant with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) identifier frames. Each channel provides 32 mailboxes with programmable priority and acceptance filtering, enabling concurrent handling of multiple CAN networks - for example, one for vehicle diagnostics (UDS) and another for actuator control. The R5F56519FGLJ#20's CAN peripherals are clocked from PCLKB and support bit rates up to 1 Mbps with programmable sample points and synchronization jump width.

What is the package type and pin count of the R5F56519FGLJ#20, and is it RoHS-compliant?

The R5F56519FGLJ#20 is housed in a PLQP0176KB-A package: a 176-pin Low-Profile Quad Flat Package (LFBGA) measuring 24 × 24 mm with 0.5-mm pitch. It is RoHS-compliant and rated for industrial temperature range (–40°C to +105°C). This package provides 136 general-purpose I/O pins - including 19 with 5-V tolerance - and dedicated signal routing for high-speed interfaces like Ethernet MII, QSPI, and SD buses. The R5F56519FGLJ#20's pinout is fully documented in Renesas Document R01DS0276EJ0240, Section 5 "Pin Functions".
