What is the maximum operating frequency and CPU architecture of the R5F564MLDDBG#21?

The R5F564MLDDBG#21 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core, delivering 240 DMIPS performance. Its architecture features a 5-stage pipeline, Harvard memory layout, variable-length instructions, and single-cycle 32×32-bit multiplication - all confirmed in the R01DS0173EJ0120 datasheet Rev.1.20. The R5F564MLDDBG#21 uses this core to execute deterministic real-time tasks in industrial control applications.

Does the R5F564MLDDBG#21 support IEEE 1588 Precision Time Protocol?

Yes, the R5F564MLDDBG#21 includes a dedicated PTP controller (EPTPC) compliant with IEEE 1588-2008, tightly coupled to both Ethernet MACs. It provides hardware timestamping of ingress/egress frames with sub-microsecond resolution - critical for time-sensitive networking in industrial automation. This capability is explicitly documented for the 177-pin variant in Section 1.1 and Table 1.2 of R01DS0173EJ0120 Rev.1.20.

What USB functionality does the R5F564MLDDBG#21 provide, and is it compatible with battery charging?

The R5F564MLDDBG#21 integrates the USBA module - a full-speed USB 2.0 host/function/OTG controller with built-in transceiver and 8.5 KB on-chip RAM buffer. It supports USB Battery Charging Specification v1.2 (BC1.2), enabling direct charging of connected devices without external charger-detection ICs. This feature is exclusive to 176-/177-pin RX64M variants, as specified in the "Features" section of R01DS0173EJ0120 Rev.1.20.

How many analog-to-digital converter channels does the R5F564MLDDBG#21 have, and what are their key capabilities?
