Overview

R5F56719DDBP#20 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, SD host interface, and capacitive touch sensing - deployed in industrial HMI and smart metering systems requiring real-time control and secure firmware updates.

For engineers reviewing the R5F56719DDBP#20 datasheet, R5F56719DDBP#20 pinout, R5F56719DDBP#20 application, or R5F56719DDBP#20 equivalent, key selection criteria include its 144-pin LFQFP package, -40°C to +85°C temperature grade, TSIP-based AES256/SHA256 encryption, and hardware-accelerated QSPIX boot-from-serial-flash capability.

Technical Context

The R5F56719DDBP#20 implements the RXv3 CPU core with collective register bank save, memory protection unit (MPU), and JTAG/FINE debug interfaces. It integrates dual-clock domain operation: ICLK up to 120 MHz for CPU and QSPIX, and PCLKA/PCLKB up to 120 MHz/60 MHz respectively for peripherals including MTU3a timers and S12AD converters.

Its peripheral architecture includes EXDMACa (2-channel extended DMA), DTCb (1-channel data transfer controller), and ELC (event link controller) enabling zero-CPU-intervention signal chaining between RTC alarms, TPU capture events, and A/D conversion triggers - critical for deterministic real-time response in safety-compliant IEC60730 applications.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56719DDBP#20?

The R5F56719DDBP#20 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's dual-issue pipeline, collective register bank save, and zero-wait-state access to 384 KB SRAM - enabling deterministic execution of complex control algorithms in real-time industrial applications. The R5F56719DDBP#20 delivers this throughput while maintaining low power consumption across four configurable low-power modes.

Does the R5F56719DDBP#20 support secure boot and firmware updates?

Yes, the R5F56719DDBP#20 supports secure boot and firmware updates via its Trusted Secure IP (TSIP) module, which provides hardware-accelerated AES128/192/256, SHA256, RSA, and ECC operations alongside a true random number generator. The dual-bank flash architecture allows background programming (BGO) of the inactive bank while the active bank runs - enabling atomic, fail-safe firmware updates without system interruption. This capability is integral to the R5F56719DDBP#20's compliance with IEC60730 Class B safety requirements.

What package type and pin count does the R5F56719DDBP#20 use?

The R5F56719DDBP#20 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size, 0.50-mm pin pitch, and RoHS-compliant lead-free finish. This LFQFP variant provides 113 general-purpose I/O pins with 5-V tolerance on 20 pins, open-drain capability on all I/Os, and dedicated signals for USB, CAN, SDHI, and QSPIX - making it suitable for industrial PCBs requiring mechanical robustness and thermal reliability. The R5F56719DDBP#20's pinout is fully documented in Renesas' R01DS0373EJ0120 datasheet Section 5.

Can the R5F56719DDBP#20 interface directly with SD cards and serial NOR flash?

Yes, the R5F56719DDBP#20 integrates both an SD host interface (SDHI) supporting 1-/4-bit SD/SDIO buses at up to 25 MB/s and a Quad-SPI memory interface (QSPIX) compatible with extended SPI, dual-SPI, and quad-SPI protocols. The SDHI complies with SD Physical Layer Specification v3.01 and supports CRC7/CRC16 error checking, while QSPIX enables direct execution (XIP) from serial NOR flash using 32-bit addressing. These interfaces eliminate external controllers, reducing BOM cost and board area in the R5F56719DDBP#20-based designs.

What analog and human-interface peripherals are integrated into the R5F56719DDBP#20?

The R5F56719DDBP#20 integrates two 12-bit A/D converter units (S12ADFa) with 8+12 channels, an on-die temperature sensor (±1°C accuracy), and a capacitive touch sensing unit (CTSUa) supporting up to 17 self-capacitance keys. The A/D converters feature sample-and-hold, digital comparison, and self-diagnostic functions; the temperature sensor feeds into S12AD unit 1 for calibration; and CTSU includes built-in noise rejection for reliable touch detection in noisy industrial environments - all without requiring external components in the R5F56719DDBP#20 implementation.
