For engineers reviewing the R5F564MLDGFP#V1 datasheet, R5F564MLDGFP#V1 pinout, R5F564MLDGFP#V1 application, or R5F564MLDGFP#V1 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + PTP timing capability, on-chip AES/SHA encryption, and support for IEC60730 functional safety diagnostics - all verified in Rev.1.20 of R01DS0173EJ0120.

Technical Context

The R5F564MLDGFP#V1 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent Ethernet controllers (ETHERC) with dedicated EPTPC hardware for IEEE 1588 timestamping and EDMAC DMA channels optimized for zero-copy frame handling.

Its clock system supports simultaneous operation at multiple domains: ICLK up to 120 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers and ADCs. The device includes three independent A/D units (S12AD0: 8ch, S12AD1: 21ch), each with configurable sample-and-hold, self-diagnostic voltage generation, and digital comparison logic tied to ELC event linking.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F564MLDGFP#V1?

The R5F564MLDGFP#V1 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 and includes a single-precision IEEE-754 floating-point unit. This performance level is confirmed in Section 1.1 of the R01DS0173EJ0120 datasheet Rev.1.20, which specifies the core's instruction set, register layout, and timing characteristics for the R5F564MLDGFP#V1 variant.

Does the R5F564MLDGFP#V1 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MLDGFP#V1 supports IEEE 1588 through dedicated hardware: the EPTPC (PTP Controller for Ethernet Controller) block tightly coupled to both Ethernet MACs. It provides hardware timestamping of ingress/egress frames with sub-microsecond resolution, independent of CPU load. This implementation is documented in Section 1.1 and Figure 1.1 of R01DS0173EJ0120 Rev.1.20, confirming full PTP profile compatibility for industrial time-sensitive networking applications.

What are the flash and RAM capacities of the R5F564MLDGFP#V1, and are they accessible without wait states?

The R5F564MLDGFP#V1 integrates 4 MB of on-chip code flash memory and 512 KB of SRAM, both accessible at 120 MHz with zero wait states. It also includes 64 KB of reprogrammable data flash (100,000 erase cycles) and 32 KB of ECC-protected RAM. These values are explicitly listed in Table 1.1 (Pages 2–3) of R01DS0173EJ0120 Rev.1.20, and the "no wait states" behavior is guaranteed under rated voltage and temperature conditions for the R5F564MLDGFP#V1 package variant.

Which communication interfaces does the R5F564MLDGFP#V1 support for industrial connectivity?

The R5F564MLDGFP#V1 supports dual IEEE 802.3 Ethernet (10/100 Mbps, MII/RMII), full-speed USB 2.0 with battery charging (USBA), three ISO11898-1 CAN channels, nine SCI/SCIg/SCIh serial interfaces, four SCIFA UARTs with 16-byte FIFOs, two I2C buses (up to 1 Mbps), QSPI, SD host interface, and RSPI. All are confirmed for the 176-pin LFBGA package in Tables 1.1–1.2 of R01DS0173EJ0120 Rev.1.20, with Ethernet and USB battery charging exclusive to this pin count.

Is the R5F564MLDGFP#V1 qualified for functional safety standards like IEC60730?

Yes, the R5F564MLDGFP#V1 includes hardware features required for Class B compliance per IEC60730: oscillation-stop detection, built-in CRC calculation unit, self-diagnostic A/D converter with internal reference voltages, independent watchdog timer (IWDTa) with window function, and register write protection. These capabilities are detailed in Section 1.1 "Useful functions for IEC60730 compliance" of R01DS0173EJ0120 Rev.1.20, specifically validated for the R5F564MLDGFP#V1 G-version (-40°C to +105°C).
