For engineers reviewing the R5F56719HDLE#20 datasheet, R5F56719HDLE#20 pinout, R5F56719HDLE#20 application, or R5F56719HDLE#20 equivalent, key selection criteria include its 145-pin TFLGA (0.65 mm pitch) package, IEC60730-compliant safety features (TSIP, MPU, self-diagnostic A/D), RTC with battery backup, and hardware-accelerated cryptographic functions (AES128/192/256, ECC, TRNG).

Technical Context

The R5F56719HDLE#20 implements the RXv3 CPU core with 16 general-purpose 32-bit registers, double-precision FPU (16×64-bit data registers), and collective register bank save for fast context switching. It supports little-endian or big-endian data arrangement and executes instructions at one per cycle at 120 MHz.

Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), LOCO/HOCO (240 kHz / 16–20 MHz), and IWDT-dedicated 120 kHz oscillator. Peripheral clocks are independently configurable: PCLKA up to 120 MHz (for MTU, RSPI, RIICHS), PCLKB up to 60 MHz (for most peripherals), and ADCLK up to 60 MHz (S12AD units).

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56719HDLE#20?

The R5F56719HDLE#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 single-cycle instruction execution, 16 general-purpose registers, and efficient pipeline - enabling deterministic real-time response in applications like motor control and protocol processing. The R5F56719HDLE#20 maintains this speed across its 384 KB SRAM and 2 MB flash with zero-wait access below 60 MHz and one-wait access at full 120 MHz.

Does the R5F56719HDLE#20 support hardware cryptographic acceleration?

Yes, the R5F56719HDLE#20 integrates Trusted Secure IP (TSIP) with dedicated hardware engines for AES128/192/256, TDES, ARC4, RSA, ECC, SHA1/224/256, MD5, GHASH, and a true-random number generator (TRNG). These accelerate secure boot, encrypted firmware updates, and TLS stack operations - reducing CPU load and meeting IEC60730 Class B requirements. Key protection mechanisms prevent illicit copying, and all crypto operations are isolated from general memory space.

What package type and pin count does the R5F56719HDLE#20 use?

The R5F56719HDLE#20 uses the PTLG0145JC-A package: a 145-pin Thin Fine-Pitch Land Grid Array (TFLGA) with 9 mm × 9 mm body size, 0.65 mm pitch, and 0.75 mm height. It provides 111 general-purpose I/O pins (20 of which are 5-V tolerant), plus dedicated power, clock, reset, and interface signals. This package supports high-density PCB layouts while enabling full peripheral access - including USB, CAN, SDHI, and QSPIX - without signal multiplexing compromises.

Can the R5F56719HDLE#20 operate in low-power modes with RTC and backup RAM retention?

Yes, the R5F56719HDLE#20 supports four low-power modes, including deep software standby where the CPU and most peripherals halt while retaining RTC time, backup registers, and 4 KB of standby RAM powered by VBATT. In this mode, current consumption drops to microamp levels, and wake-up can occur via IRQ pins, RTC alarm, or external reset. The sub-clock oscillator (32.768 kHz) remains active, ensuring ±1 ppm timekeeping accuracy during backup operation.

What safety certifications and diagnostic features does the R5F56719HDLE#20 support?

The R5F56719HDLE#20 includes features aligned with IEC60730 Class B compliance: oscillation-stop detection, hardware CRC accelerator, independent watchdog timer (IWDTa) with windowing, self-diagnostic A/D converter test, memory protection unit (MPU), and register write protection. These allow runtime verification of clock integrity, memory correctness, and peripheral functionality - reducing software validation burden and supporting safety-critical industrial control applications without external monitors.
