Product details
Overview
R5F5651CHDFB#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 channels, and hardware AES encryption - deployed in industrial HMIs with integrated graphics and secure connectivity.
For engineers reviewing the R5F5651CHDFB#10 datasheet, R5F5651CHDFB#10 pinout, R5F5651CHDFB#10 application, or R5F5651CHDFB#10 equivalent, key selection criteria include its 176-pin LFBGA package, 120-MHz real-time performance with MPU and TSIP security, dual-bank flash for safe firmware updates, and integrated GLCDC/DRW2D for embedded display subsystems.
Technical Context
The R5F5651CHDFB#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) supporting eight configurable regions. It integrates dual-clock domains: ICLK up to 120 MHz for CPU/core logic, and PCLKA/PCLKB up to 120 MHz/60 MHz respectively for peripherals including ETHERC, DRW2D, and S12AD.
Its peripheral set is partitioned across clock domains and power modes: Ethernet MAC and USB 2.0 FS operate under PCLKA; A/D converters (S12AD) use dedicated PCLKC/PCLKD; RTC and IWDT run from independent low-frequency oscillators (LOCO/HOCO). The device supports IEC60730 functional safety via CRC, self-diagnostic A/D, oscillation-stop detection, and register write protection.
