Overview
R5F56514AGFB#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 120 MHz (240 DMIPS), featuring 1 MB on-chip code flash, 640 KB SRAM (no wait states), single-precision IEEE-754 FPU, and integrated Ethernet MAC, CAN, SD host/slave, QSPI, and GLCDC for industrial HMI applications.
For engineers reviewing the R5F56514AGFB#30 datasheet, R5F56514AGFB#30 pinout, R5F56514AGFB#30 application, or R5F56514AGFB#30 equivalent, key selection criteria include dual-bank flash for safe firmware updates, 136 GPIOs with 5-V tolerance, RTC with battery backup, AES-128/192/256 encryption, and IEC60730 safety support including CRC, IWDT, and self-diagnostic A/D.
Technical Context
The R5F56514AGFB#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates a memory protection unit (MPU) supporting eight configurable regions and Trusted Memory (TM) for secure code execution in designated flash areas.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL for flexible domain partitioning: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for ETHERC/EDMAC/GLCDC/DRW2D, and PCLKB up to 60 MHz for most peripherals including S12AD units.
