For engineers reviewing the R5F56519EGLJ#20 datasheet, R5F56519EGLJ#20 pinout, R5F56519EGLJ#20 application, or R5F56519EGLJ#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), -40°C to +85°C operating range, 2-channel CAN compliance with ISO11898-1, and hardware-accelerated AES-128/192/256 plus TSIP for IEC60730-compliant safety-critical firmware.

Technical Context

The R5F56519EGLJ#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU-enforced memory protection across eight configurable regions. It integrates dual-clock domain operation: ICLK up to 120 MHz for CPU/core logic, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, EDMAC, AES, GLCDC), and PCLKB up to 60 MHz for timers, ADC, and communication interfaces.

Its peripheral subsystem includes a dedicated 120-kHz IWDT clock source, RTC with battery backup and time-capture, two independent 12-bit A/D units (8+21 channels), dual 12-bit D/A converters, and event-linking controller (ELC) enabling hardware-triggered inter-module coordination without CPU intervention - critical for deterministic real-time control in industrial automation.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F56519EGLJ#20?

The R5F56519EGLJ#20 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with 5-stage pipeline, Harvard architecture, and variable-length instruction set. It delivers 240 DMIPS and includes a single-precision IEEE-754 floating-point unit. This architecture enables deterministic real-time execution and efficient code density for industrial firmware deployed on the R5F56519EGLJ#20.

Does the R5F56519EGLJ#20 support Ethernet connectivity, and what physical layer options are available?

Yes, the R5F56519EGLJ#20 integrates a full-featured Ethernet MAC compliant with IEEE 802.3, supporting 10/100 Mbps in full- and half-duplex modes. It provides MII and RMII interfaces for connection to external PHYs, along with Magic Packet™ wake-on-LAN and IEEE 802.3x flow control. The R5F56519EGLJ#20 does not include an on-die PHY - external PHY selection (e.g., LAN8720A) is required for physical layer implementation.

What safety and security features are built into the R5F56519EGLJ#20 for industrial certification?

The R5F56519EGLJ#20 includes MPU-based memory protection, Trusted Memory (TM) for code flash read protection, register write protection, CRCA for 8-/32-bit CRC generation, oscillation-stop detection, and self-diagnostic A/D functionality - all aligned with IEC60730 Class B requirements. Its TSIP module provides certified AES-128/192/256 encryption and secure key management, enabling secure boot and firmware integrity verification on the R5F56519EGLJ#20.

How many analog-to-digital converter channels does the R5F56519EGLJ#20 provide, and what resolution options are supported?

The R5F56519EGLJ#20 integrates two independent 12-bit A/D converter units: S12ADFa Unit 0 with 8 input channels and Unit 1 with 21 input channels. Both units support selectable resolution of 8-, 10-, or 12-bit per conversion, with minimum conversion times of 0.42 µs (8-bit), 0.45 µs (10-bit), and 0.48 µs (12-bit). The R5F56519EGLJ#20 also includes channel-dedicated sample-and-hold for three channels in Unit 0 and analog input disconnection detection.

What is the package type and pin count of the R5F56519EGLJ#20, and is it RoHS-compliant?

The R5F56519EGLJ#20 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array with 24 × 24 mm body size and 0.5-mm ball pitch. It is RoHS-compliant and lead-free solder process compatible. This package provides 136 general-purpose I/O pins (19 with 5-V tolerance), supporting industrial-level noise immunity and high-density PCB layouts required for compact edge devices built around the R5F56519EGLJ#20.
