For engineers reviewing the R5F564MGGDFC#31 datasheet, R5F564MGGDFC#31 pinout, R5F564MGGDFC#31 application, or R5F564MGGDFC#31 equivalent, key selection criteria include its 177-pin TFLGA package with 127 GPIOs (19 × 5-V tolerant), dual-channel IEEE 1588 PTP hardware timestamping, 64 KB data flash rated for 100,000 erase/write cycles, and built-in AES/SHA/DES encryption accelerators for secure boot and OTA updates.

Technical Context

The R5F564MGGDFC#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 MACs with dedicated EPTPC hardware compliant with IEEE 1588-2008 for sub-microsecond time synchronization, plus three CAN modules (ISO 11898-1) each supporting 32 mailboxes for robust automotive and industrial bus communication.

Its memory subsystem includes 4 MB zero-wait-state code flash, 512 KB SRAM (no wait states), 32 KB ECC-protected RAM (SEC-DED), and 8 KB standby RAM backed by VBATT. Clocking supports external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL multiplication - with independent domain clocks (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz) enabling precise peripheral timing control.

FAQ

What is the maximum operating frequency and core architecture of the R5F564MGGDFC#31?

The R5F564MGGDFC#31 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. This core enables deterministic real-time execution critical for industrial control loops and time-sensitive network protocols supported by the R5F564MGGDFC#31.

Does the R5F564MGGDFC#31 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F564MGGDFC#31 integrates two dedicated IEEE 1588-compliant Ethernet MACs with an embedded PTP controller (EPTPC) that provides hardware timestamping for both transmit and receive frames. This enables sub-microsecond clock synchronization accuracy required in industrial PLCs and motion controllers - a capability confirmed in the R01DS0173EJ0120 datasheet and intrinsic to the R5F564MGGDFC#31's dual-MAC architecture.

What package type and pin count does the R5F564MGGDFC#31 use?

The R5F564MGGDFC#31 uses a 177-pin TFLGA package (PTLG0177KA-A), measuring 8 mm × 8 mm with 0.5 mm pitch. It provides 127 general-purpose I/O pins, of which 19 are 5-V tolerant, along with dedicated VBATT, AVCC, and multi-domain power pins. This compact, fine-pitch package supports high-density industrial PCB layouts while maintaining thermal and electrical integrity under extended temperature operation (–40°C to +105°C).

How much on-chip memory does the R5F564MGGDFC#31 include, and what are its endurance specifications?

The R5F564MGGDFC#31 includes 4 MB of on-chip code flash memory (zero wait states at 120 MHz), 512 KB of SRAM, 64 KB of reprogrammable data flash rated for 100,000 erase/write cycles, and 32 KB of ECC-protected RAM with SEC-DED error correction. These memory resources are fully specified in the R01DS0173EJ0120 datasheet and enable robust firmware storage, real-time data buffering, and fail-safe parameter retention - all integral to the R5F564MGGDFC#31's target applications.

What security features are implemented in hardware on the R5F564MGGDFC#31?

The R5F564MGGDFC#31 integrates dedicated hardware accelerators for AES (128/192/256-bit), DES/T-DES, and SHA-1/224/256 cryptographic operations, plus a hardware CRC module, memory protection unit (MPU), and register write protection. These features enable secure boot, encrypted firmware updates, and runtime data protection - all documented in the R01DS0173EJ0120 datasheet as standard capabilities of the R5F564MGGDFC#31, not optional configurations.
