For engineers reviewing the R5F564MJDDFB#31 datasheet, R5F564MJDDFB#31 pinout, R5F564MJDDFB#31 application, or R5F564MJDDFB#31 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), confirmed peripheral channel counts for Ethernet/USB/CAN, and two validated alternative MCUs with documented functional and packaging differences.

Technical Context

The R5F564MJDDFB#31 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, dual multiply-and-accumulate units, and hardware division - enabling real-time signal processing in motor control and power conversion. Its clock architecture supports independent domain scaling: 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.

It integrates three CAN modules (ISO 11898-1 compliant, 32 mailboxes each), dual IEEE 1588-capable Ethernet controllers with EPTPC timestamping, and a full-speed USB 2.0 host/function module with battery charging support - all mapped to dedicated DMA channels (EDMACa: 3 channels; DMACa: 8 channels) to offload CPU bandwidth in protocol stack implementations.
