Renesas R5F56514FGFM#30

Overview

R5F56514FGFM#30 from Renesas is a 32-bit RXv2 microcontroller operating at up to 120 MHz, delivering 240 DMIPS with integrated single-precision IEEE-754 FPU, 1.5 MB on-chip code flash memory, 640 KB SRAM (including 8 KB standby RAM), and dual-bank flash architecture enabling background programming. It integrates Ethernet MAC, CAN (2 channels), SD host/slave interfaces, QSPI, GLCDC, DRW2D, and hardware AES encryption - targeting industrial HMI, networked gateway, and secure embedded control applications.

For engineers reviewing the R5F56514FGFM#30 datasheet, R5F56514FGFM#30 pinout, R5F56514FGFM#30 application, or R5F56514FGFM#30 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 120-MHz real-time performance with MPU and TSIP security, dual-bank flash for safe firmware updates, and full peripheral integration including Ethernet PHY support, 21-channel 12-bit A/D converter (unit 1), and 2-channel D/A converter.

Technical Context

The R5F56514FGFM#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, supporting little- or big-endian data arrangement and executing floating-point, DSP, and multiply-accumulate operations in hardware. Its clock system uses PLL multiplication of external crystal or internal HOCO (16/18/20 MHz) to achieve 120 MHz ICLK, while peripheral clocks (PCLKA/PCLKB) are independently configurable up to 120 MHz and 60 MHz respectively.

Peripheral subsystems operate under strict clock domain separation: ETHERC, EDMAC, AES, GLCDC, and DRW2D synchronize to PCLKA (≤120 MHz); S12AD unit 1 runs on PCLKD (≤60 MHz); and RTC, IWDT, and low-power modes rely on dedicated LOCO (240 kHz) or sub-clock sources. The ELC enables zero-CPU-latency interconnection of 83 internal event signals across timers, ADC, and communication modules.
