It targets industrial automation controllers requiring real-time deterministic communication, secure firmware updates, and high-precision analog sensing.

For engineers reviewing the R5F564MLDGFB#V1 datasheet, R5F564MLDGFB#V1 pinout, R5F564MLDGFB#V1 application, or R5F564MLDGFB#V1 equivalent, key selection criteria include its 176-pin LFBGA package (PLBG0176GA-A), dual Ethernet + PTP support, on-chip AES/SHA encryption, 32 KB ECC-protected RAM, and -40°C to +105°C G-grade operation.

Technical Context

The R5F564MLDGFB#V1 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. Its clock system combines external crystal oscillation (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL for independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz).

It integrates dual Ethernet MACs with dedicated EDMAC (3-channel) and EPTPC (IEEE 1588 PTP) hardware, plus USBA with 8.5 KB buffer and battery charging support - features confirmed only for 176- and 177-pin variants per datasheet Table 1.2 and Section 1.1.

Yes, the R5F564MLDGFB#V1 includes a dedicated IEEE 1588-compliant PTP controller (EPTPC) tightly coupled to its dual Ethernet MACs. Hardware timestamping occurs at packet ingress/egress with sub-microsecond resolution, enabling time-synchronized industrial networks. This capability is explicitly documented for 176- and 177-pin RX64M variants in Section 1.1 and Table 1.2 of R01DS0173EJ0120 Rev.1.20 - confirming full PTP support in R5F564MLDGFB#V1.

What are the memory resources available on the R5F564MLDGFB#V1?

The R5F564MLDGFB#V1 integrates 4 MB of on-chip code flash memory (no wait states at 120 MHz), 512 KB of general-purpose SRAM (no wait), 32 KB of ECC-protected RAM (SEC-DED), and 64 KB of reprogrammable data flash rated for 100,000 erase/write cycles. These values are specified in Table 1.1 (pages 2–3) of R01DS0173EJ0120 Rev.1.20. The memory architecture directly supports complex industrial firmware, real-time data buffering, and secure key storage in R5F564MLDGFB#V1-based designs.
