FAQ

What is the maximum operating frequency and CPU architecture of the R5F564MGGDLJ#21?

The R5F564MGGDLJ#21 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit (FPU) for real-time signal processing tasks. This architecture enables deterministic execution critical for industrial control loops and time-sensitive communications stacks.

Does the R5F564MGGDLJ#21 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MGGDLJ#21 supports IEEE 1588 through its integrated EPTPC (PTP controller for Ethernet) block, which provides hardware timestamping for both transmit and receive Ethernet frames. The EPTPC connects directly to the dual ETHERC modules and supports PTP event message handling, clock synchronization, and best master clock algorithm support-enabling sub-microsecond time alignment across distributed nodes without external timing ICs.

What package type and pin count does the R5F564MGGDLJ#21 use, and what are its thermal specifications?

The R5F564MGGDLJ#21 uses a 177-ball LFBGA package (PLBG0176GA-A), measuring 13 × 13 mm with 0.8-mm pitch. It is rated for the G-version industrial temperature range of –40°C to +105°C, making it suitable for fanless enclosures and high-ambient environments. The package features 127 general-purpose I/O pins, including 19 × 5-V tolerant inputs for interfacing with legacy 5-V logic and sensors.

How does the R5F564MGGDLJ#21 support functional safety standards like IEC 60730?

The R5F564MGGDLJ#21 includes multiple hardware features for IEC 60730 Class B compliance: oscillation-stop detection, built-in CRC calculation unit, independent watchdog timer (IWDTa) with window function, register write protection, and A/D converter self-diagnostic capability that generates internal reference voltages for validation. These features enable automated runtime checks without software overhead-reducing certification effort for household and industrial appliances.

What are the memory resources available on the R5F564MGGDLJ#21, and how are they allocated?

The R5F564MGGDLJ#21 integrates 4-MB on-chip code flash (zero-wait-state at 120 MHz), 64-KB reprogrammable data flash (100,000 write cycles), 512-KB SRAM (no wait), 32-KB RAM with SEC-DED ECC for safety-critical variables, and 8-KB standby RAM backed by VBATT. Flash blocks 8 and 9 are protected by Trusted Memory (TM) to prevent unauthorized read-out-supporting secure boot and firmware IP protection.
