Product details
Overview
R5F56719DDFB#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, secure firmware updates, and low-power operation.
For engineers reviewing the R5F56719DDFB#10 datasheet, R5F56719DDFB#10 pinout, R5F56719DDFB#10 application, or R5F56719DDFB#10 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-B (144-pin LFQFP), functional pin roles, IEC60730-compliant safety features, and validated alternative MCUs for migration or second-sourcing.
Technical Context
The R5F56719DDFB#10 implements the RXv3 CPU core with 113 instructions, including 21 double-precision FPU ops and DSP extensions, supporting little-endian or big-endian data arrangement and register bank save across 16 banks. It integrates a memory protection unit (MPU) with eight configurable regions (min. 16-byte granularity) and supports TrustZone-like isolation via Trusted Memory (TM) for secure code execution.
Its clock architecture uses independent PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and sub-clock (32.768 kHz) sources, enabling asynchronous domain control: ICLK up to 120 MHz for CPU/QSPIX, PCLKA up to 120 MHz for MTU/RSPI/RIICHS, and PCLKB up to 60 MHz for most peripherals and ADC clocks - ensuring deterministic timing for mixed-criticality tasks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F56709DDFB#10 | Same RX671 Group, 1 MB flash (vs. 2 MB), identical pinout and peripheral set except reduced SRAM (256 KB vs. 384 KB) | Suitable for cost-sensitive designs where firmware size < 1 MB and buffer requirements are lower | Select when full 2 MB flash and 384 KB SRAM are not required; maintains drop-in compatibility on PLQP0144KA-B layout |
| R5F572N9DDFB#10 | RX72N Group part: higher 240 MHz CPU, 4 MB flash, but different pinout (144-pin TFLGA), no SDHI or QSPIX, adds Ethernet MAC | Better for networked edge controllers needing TCP/IP stack, but requires PCB redesign and lacks serial flash boot capability | Choose only if Ethernet connectivity is mandatory and flash/SRAM scaling justifies board revision and toolchain migration |
Compared with R5F56719DDFB#10, R5F56709DDFB#10 offers identical peripheral functionality at lower memory cost with zero layout change, while R5F572N9DDFB#10 trades serial memory interface and SD support for Ethernet - making it unsuitable for flash-booted or SD-dependent deployments without hardware rework.

It supports secure boot, encrypted firmware updates via dual-bank flash, and key protection against extraction - meeting IEC60730 Class B requirements for safe field upgrades.
What package type and pin count does the R5F56719DDFB#10 use?
The R5F56719DDFB#10 uses the PLQP0144KA-B package: a 144-pin LQFP measuring 20 × 20 mm with 0.50-mm pitch. It provides 114 general-purpose I/O pins (20 of which are 5-V tolerant), and shares pin compatibility with other RX671 variants in the same package family - simplifying design reuse across memory configurations.
Can the R5F56719DDFB#10 boot directly from external serial flash memory?
Yes, the R5F56719DDFB#10 supports execute-in-place (XIP) booting from external serial flash via its QSPIX interface.
