FAQ

What is the maximum operating frequency and CPU performance of the R5F56519FDFB#10?

The R5F56519FDFB#10 operates at a maximum frequency of 120 MHz using the RXv2 32-bit CPU core and delivers 240 DMIPS of processing performance. Its single-precision IEEE-754 floating-point unit (FPU) and dual multiply-accumulate units enable efficient signal processing and control loop calculations. This performance level is validated under typical operating conditions (2.7–3.6 V, –40°C to +85°C) and supports real-time deterministic execution required in industrial automation and medical devices.

Does the R5F56519FDFB#10 include hardware encryption and safety features for certified applications?

Yes, the R5F56519FDFB#10 integrates AES-128/192/256 encryption, Trusted Secure IP (TSIP) for key management and secure boot, and comprehensive IEC60730 compliance features including oscillation-stop detection, CRC calculator (CRCA), independent watchdog timer (IWDTa) with windowing, A/D converter self-diagnostic, and register write protection. These capabilities allow developers to achieve Class B certification for industrial and medical equipment without adding external security ICs or safety monitors.

What package type and pin count does the R5F56519FDFB#10 use?

The R5F56519FDFB#10 uses the PLQP0176KB-A package: a 176-pin LQFP measuring 24 × 24 mm with 0.5 mm pitch. It provides 136 general-purpose I/O pins, including 19 with 5-V tolerance, configurable pull-up resistors, and open-drain outputs. This package matches the full peripheral complement of the RX65N Group's high-pin-count variants, supporting all integrated interfaces including Ethernet, dual CAN, SDHI, and GLCDC.

Can the R5F56519FDFB#10 support simultaneous Ethernet and CAN communication in a gateway application?

Yes, the R5F56519FDFB#10 natively supports concurrent Ethernet (10/100 Mbps MAC with RMII/MII) and dual CAN (ISO11898-1 compliant, 32 mailboxes per channel) operation. Its multi-channel DMA controllers (DMACAa, EXDMAC, EDMAC) and Event Link Controller (ELC) enable zero-CPU-intervention data movement between these interfaces and memory - allowing real-time protocol bridging (e.g., Modbus TCP ↔ CANopen) without performance degradation or packet loss.

What graphics and display capabilities does the R5F56519FDFB#10 offer for HMI development?

The R5F56519FDFB#10 integrates a Graphic-LCD Controller (GLCDC) supporting 24-bit RGB output, 3-layer plane superposition (background, graphic 1, graphic 2), and programmable timing for TFT panels up to VGA resolution. Paired with the 2D Drawing Engine (DRW2D), it accelerates vector graphics, bit blitting, rotation, and texture mapping - enabling responsive, multi-language UIs with minimal external memory. These features eliminate the need for external GPU or display controller ICs in industrial HMI designs.
