Product details
Overview
R5F56719DDFP#10 from Renesas is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring double-precision IEEE-754 FPU, 2 MB on-chip code flash with dual-bank support, 384 KB SRAM, and integrated CAN, USB 2.0 FS, SDHI, QSPIX, and capacitive touch sensing - deployed in industrial HMI and smart metering systems requiring real-time control and secure firmware updates.
For engineers reviewing the R5F56719DDFP#10 datasheet, R5F56719DDFP#10 pinout, R5F56719DDFP#10 application, or R5F56719DDFP#10 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-B (144-pin LFQFP), functional pin roles, IEC60730-compliant safety features, and two validated alternative MCUs for migration paths in embedded control designs.
Technical Context
The R5F56719DDFP#10 implements the RXv3 CPU core with 113 instructions, including 21 double-precision FPU operations and DSP extensions, supporting little-endian or big-endian data arrangement and 4-Gbyte linear address space. It integrates a memory protection unit (MPU) with eight configurable regions and collective register bank save across 16 banks for deterministic interrupt latency.
Its clock system combines external crystal (8–24 MHz), sub-clock (32.768 kHz), and internal oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocks: ICLK up to 120 MHz for CPU/QSPIX, PCLKA up to 120 MHz for MTU/RSPI, and PCLKB up to 60 MHz for most peripherals and ADCs. The ELC interlinks 99 internal events to eliminate CPU polling overhead.
