For engineers reviewing the R5F56519FGLK#20 datasheet, R5F56519FGLK#20 pinout, R5F56519FGLK#20 application, or R5F56519FGLK#20 equivalent, this page delivers verified package mapping (176-pin LFBGA, PLQP0176KB-A), confirmed peripheral clock domains (ICLK ≤ 120 MHz, PCLKA ≤ 120 MHz, PCLKB ≤ 60 MHz), validated dual-bank flash operation, and precise I/O capability (136 general-purpose pins with 5-V tolerance on 19 pins).

Technical Context

The R5F56519FGLK#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dedicated clock domains: ICLK for CPU execution, PCLKA for high-speed peripherals (ETHERC, GLCDC, DRW2D), and PCLKB for timers and analog modules - enabling deterministic timing isolation across subsystems.

Its memory subsystem includes dual-bank 2-MB code flash supporting background programming and bank-swapping during runtime, 640-KB SRAM (256 KB main + 384 KB expansion), and 32-KB data flash rated for 100,000 erase/write cycles. Peripheral coherency is maintained via ELC (Event Link Controller), allowing 83 internal event signals to trigger timer actions, A/D conversions, or DMA transfers without CPU intervention.

FAQ

What is the maximum operating frequency and CPU performance of the R5F56519FGLK#20?

The R5F56519FGLK#20 operates at a maximum system clock (ICLK) of 120 MHz and delivers 240 DMIPS. Its RXv2 core supports single-precision IEEE-754 floating-point operations, 32-bit multiplier (1-cycle), and 32-bit divider (2-cycle), enabling deterministic real-time math in motion control and signal processing applications. The R5F56519FGLK#20 achieves this performance with no wait states up to 50 MHz on code flash and full 120 MHz on 640 KB SRAM.

Does the R5F56519FGLK#20 support dual-bank flash operation and background programming?

Yes, the R5F56519FGLK#20 features a dual-bank 2-MB code flash architecture that supports background programming (BGO) and runtime bank swapping. This allows the R5F56519FGLK#20 to execute from one bank while reprogramming the other - essential for fail-safe firmware updates in networked industrial devices without service interruption.

What peripheral clock domains does the R5F56519FGLK#20 use, and why does it matter?

The R5F56519FGLK#20 uses independent clock domains: ICLK (≤120 MHz) for CPU, PCLKA (≤120 MHz) for Ethernet, GLCDC, and DRW2D, and PCLKB (≤60 MHz) for timers and analog modules. This domain separation ensures deterministic timing - for example, Ethernet packet handling won't stall A/D sampling or PWM generation, which is critical for IEC 60730-compliant systems. The R5F56519FGLK#20 assigns each peripheral to its optimal clock source to guarantee jitter-free operation.

How many general-purpose I/O pins does the R5F56519FGLK#20 provide, and what are their electrical characteristics?

The R5F56519FGLK#20 provides 136 general-purpose I/O pins in its 176-pin LFBGA package (PLQP0176KB-A). Of these, 19 pins are 5-V tolerant, all support input pull-up and open-drain output, and each can be individually configured for high-drive or low-drive strength. These I/Os enable direct interfacing with legacy 5-V sensors, industrial logic, and display interfaces - eliminating level-shifters in mixed-voltage systems using the R5F56519FGLK#20.

What security features are integrated into the R5F56519FGLK#20 for firmware and data protection?

The R5F56519FGLK#20 integrates AES-128/192/256 encryption, Trusted Secure IP (TSIP) for key management and secure boot, Memory Protection Unit (MPU) with eight configurable regions, register write protection, and CRC calculator supporting multiple polynomials. These features allow the R5F56519FGLK#20 to implement secure OTA updates, encrypted data logging, and runtime memory isolation - meeting foundational requirements for IEC 62443 and IEC 60730 Class B certification.
