For engineers reviewing the R5F564MJDDFC#31 datasheet, R5F564MJDDFC#31 pinout, R5F564MJDDFC#31 application, or R5F564MJDDFC#31 equivalent, this MCU delivers verified 240 DMIPS performance, hardware-accelerated AES/SHA encryption, dual 12-bit ADC units (29 total channels), and full-speed USB 2.0 with battery charging support - all within a 176-pin LFBGA package operating from 2.7–3.6 V.

Technical Context

The R5F564MJDDFC#31 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) for IEC 60730 Class B compliance. It integrates dual DMA controllers (DMAC: 8 channels; EXDMAC: 2 channels) and a dedicated EDMAC (3 channels) for Ethernet offload.

Clock subsystem includes PLL-based 120 MHz ICLK, independent PCLKA/PCLKB domains (up to 120 MHz / 60 MHz), and dedicated IWDT oscillator (120 kHz). Real-time clock supports binary counting, leap-year adjustment, and time-capture on external event signals.

FAQ

What is the maximum operating frequency and core architecture of the R5F564MJDDFC#31?

The R5F564MJDDFC#31 operates at a maximum frequency of 120 MHz using the RXv2 32-bit CISC Harvard architecture with 5-stage pipeline and variable-length instructions. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit (FPU), two multiply-and-accumulate units, and a 32-bit multiplier with one-cycle execution. This architecture enables deterministic real-time execution for industrial control applications.

Does the R5F564MJDDFC#31 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MJDDFC#31 includes a dedicated PTP controller (EPTPC) compliant with IEEE 1588-2008, tightly coupled to its dual Ethernet MAC modules. Hardware timestamping occurs at the physical layer with sub-microsecond resolution on both transmit and receive paths. The EPTPC supports master/slave clock roles, delay request-response mechanisms, and transparent clock functionality - enabling precise synchronization in distributed automation systems without software overhead.

What are the flash and RAM capacities of the R5F564MJDDFC#31, and how are they utilized in practice?

The R5F564MJDDFC#31 integrates 4 MB of on-chip code flash memory (no wait states at 120 MHz), 64 KB of reprogrammable data flash (rated for 100,000 erase cycles), 512 KB of general-purpose SRAM (zero wait states), 32 KB of ECC-protected RAM, and 8 KB of battery-backed standby RAM. In practice, this allows full-size encrypted firmware images, dual-bank OTA updates, real-time Ethernet stack buffering, and persistent parameter storage - all without external memory components.

How does the R5F564MJDDFC#31 meet IEC 60730 Class B safety requirements?

The R5F564MJDDFC#31 includes multiple hardware features certified for IEC 60730 Class B: oscillation-stoppage detection, hardware CRC calculation unit, independent watchdog timer (IWDTa) with window function, self-diagnostic A/D converter, register write protection, and memory protection unit (MPU). These features enable automatic fault detection and recovery without software polling - reducing certification burden for household and industrial appliances.

What package type and pin count does the R5F564MJDDFC#31 use, and what are its thermal characteristics?

The R5F564MJDDFC#31 uses the PLBG0176GA-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 13 mm × 13 mm with 0.8 mm ball pitch. It is rated for industrial temperature range (–40°C to +85°C) and features three independent power domains (VCC, AVCC0, AVCC1) for analog/digital noise isolation. Thermal resistance (θJA) is 26.5°C/W, supporting convection-cooled designs up to 1.2 W typical power dissipation.
