For engineers reviewing the R5F564MFGDFC#31 datasheet, R5F564MFGDFC#31 pinout, R5F564MFGDFC#31 application, or R5F564MFGDFC#31 equivalent, this MCU delivers verified 240 DMIPS performance, on-chip ECC-protected RAM, background data flash programming, IEC60730 self-test features, and hardware-accelerated AES/SHA encryption - critical for secure, high-integrity edge node designs.

Technical Context

The R5F564MFGDFC#31 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC + EPTPC) compliant with IEEE 1588-2008 for precise time synchronization, and supports PTP timestamping via hardware-assisted packet injection and capture.

Its clock system combines external crystal oscillators (8–24 MHz), internal HOCO/LOCO sources, and PLL-based frequency synthesis to drive independent peripheral clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz). The device includes dedicated low-power modes (deep software standby with 8 KB backup RAM), RTC with battery backup, and voltage monitoring circuits (LVDA) with configurable reset thresholds for robust operation in industrial environments.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F564MFGDFC#31?

The R5F564MFGDFC#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline and optimized instruction set. The R5F564MFGDFC#31 sustains this performance with zero-wait-state access to both 4 MB code flash and 512 KB SRAM, making it suitable for computationally intensive real-time control tasks.

Does the R5F564MFGDFC#31 support IEEE 1588 Precision Time Protocol (PTP)?

Yes, the R5F564MFGDFC#31 includes a dedicated PTP controller (EPTPC) tightly coupled to its dual Ethernet MAC modules, providing hardware timestamping compliant with IEEE 1588-2008. The R5F564MFGDFC#31 supports both one-step and two-step clock synchronization modes, enabling sub-microsecond time alignment across distributed industrial networks without CPU overhead.

What are the key security features integrated into the R5F564MFGDFC#31?

The R5F564MFGDFC#31 offers optional hardware-accelerated cryptography including AES-128/192/256, DES/TDES, and SHA-1/224/256 with HMAC. It also includes a unique 12-byte device ID, trusted memory (TM) protection for flash blocks 8–9, and register write protection for safety-critical configuration registers - all supporting IEC60730 Class B and IEC 62443-3-3 compliance workflows.

How does the R5F564MFGDFC#31 handle analog-to-digital conversion for industrial sensing?

The R5F564MFGDFC#31 integrates two independent 12-bit A/D converters (S12ADC units) with 8 and 21 input channels respectively, offering 0.48 µs per-channel conversion time. It includes self-diagnostic functions, analog input disconnection detection, and sample-and-hold circuitry - enabling reliable, safety-certifiable analog acquisition in harsh industrial environments.

What low-power modes are available on the R5F564MFGDFC#31, and how does RTC battery backup work?

The R5F564MFGDFC#31 supports four low-power modes: Sleep, All-module Clock Stop, Software Standby, and Deep Software Standby. In Deep Software Standby, the 8 KB standby RAM remains powered, and the RTC continues operation via the VBATT pin - allowing accurate timekeeping and wake-on-event functionality even when main power is removed, critical for energy metering and alarm systems.
