Product details
Overview
R5F56514BDFB#10 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 120 MHz (240 DMIPS), featuring 1 MB on-chip code flash, 256 KB SRAM, single-precision IEEE-754 FPU, Ethernet MAC, dual CAN 2.0B channels, and hardware AES-128/192/256 encryption - deployed in industrial HMIs with real-time graphics and secure networked control.
For engineers reviewing the R5F56514BDFB#10 datasheet, R5F56514BDFB#10 pinout, R5F56514BDFB#10 application, or R5F56514BDFB#10 equivalent, key selection criteria include its 176-pin LFBGA package, 120-MHz deterministic real-time performance, integrated GLCDC + DRW2D for embedded GUIs, dual-bank flash for safe firmware updates, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.
Technical Context
The R5F56514BDFB#10 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a memory protection unit (MPU) supporting eight configurable regions and Trusted Memory (TM) for secure code execution from protected flash areas.
Its clock system combines external crystal support (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL-based frequency synthesis - delivering independent clocks for CPU (ICLK ≤ 120 MHz), peripherals (PCLKA ≤ 120 MHz, PCLKB ≤ 60 MHz), ADC (ADCLK ≤ 60 MHz), and flash interface (FCLK ≤ 60 MHz).
