For engineers reviewing the R5F56719HDFB#30 datasheet, R5F56719HDFB#30 pinout, R5F56719HDFB#30 application, or R5F56719HDFB#30 equivalent, this MCU delivers deterministic real-time performance (707 CoreMark), IEC60730-compliant safety features including self-diagnostic A/D and oscillation-stop detection, and hardware-accelerated cryptography via TSIP for secure boot and OTA updates.

Technical Context

The R5F56719HDFB#30 implements the RXv3 CPU core with 16 general-purpose 32-bit registers, double-precision FPU coprocessor (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), and dedicated IWDT 120-kHz oscillator, with independent domain clocks: ICLK (up to 120 MHz for CPU/QSPIX), PCLKA (up to 120 MHz for MTU/RSPI), PCLKB (up to 60 MHz for most peripherals), and ADCLK (up to 60 MHz for S12AD units).

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56719HDFB#30?

The R5F56719HDFB#30 operates at a maximum frequency of 120 MHz and achieves 707 CoreMark under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 16 general-purpose registers, and optimized pipeline - enabling deterministic real-time response in industrial control loops and HMI rendering tasks. The R5F56719HDFB#30 sustains this speed across its 384 KB SRAM and dual-bank flash interface.

Does the R5F56719HDFB#30 support secure firmware updates and cryptographic operations?

Yes, the R5F56719HDFB#30 integrates Trusted Secure IP (TSIP) with hardware acceleration for AES128/192/256, RSA, ECC, SHA256, and a true-random number generator (TRNG). These capabilities enable secure boot verification, encrypted OTA firmware updates, and protected key storage - all required for IEC60730 Class B and IEC62443 compliance. The R5F56719HDFB#30 uses TSIP to prevent illicit copying of keys and enforce firmware integrity checks before execution.

What package type and pin count does the R5F56719HDFB#30 use?

The R5F56719HDFB#30 is packaged in PLQP0144KA-B: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size, 0.50-mm pitch, and exposed thermal pad. It provides 114 general-purpose I/O pins (20 of which are 5-V tolerant), supporting flexible peripheral routing for CAN, USB, SDHI, and QSPIX interfaces. The R5F56719HDFB#30 shares this footprint with other RX671 Group members for scalable design reuse.

How does the R5F56719HDFB#30 handle analog-to-digital conversion and self-diagnosis?

The R5F56719HDFB#30 integrates two 12-bit A/D converters (S12ADFa): Unit 0 (8 channels) and Unit 1 (12 channels), each supporting 8/10/12-bit resolution and conversion times as fast as 0.42 µs. Both units include self-diagnostic functions that internally generate reference voltages (e.g., VREFL0, VREFH0 × 1/2) to verify analog path integrity - a mandatory feature for IEC60730 Class B certification. The R5F56719HDFB#30 also detects analog input disconnection and supports digital comparison for windowed threshold monitoring.

Can the R5F56719HDFB#30 operate in low-power modes with RTC and backup RAM retention?

Yes, the R5F56719HDFB#30 supports four low-power modes, including deep software standby where only the sub-clock oscillator, RTC, and 4 KB standby RAM remain active - powered by VBATT during main supply loss. In this mode, the R5F56719HDFB#30 maintains calendar time, alarm triggers, and critical state data while consuming minimal current. Battery-backed operation ensures uninterrupted timekeeping and tamper-evident logging in smart meters and security systems using the R5F56719HDFB#30.
