Product details
Overview
R5F564MGCDBG#21 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with integrated FPU, 4 MB code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging, CAN (ISO 11898-1), and 12-bit A/D + D/A converters - deployed in industrial gateways requiring deterministic real-time control and secure connectivity.
For engineers reviewing the R5F564MGCDBG#21 datasheet, R5F564MGCDBG#21 pinout, R5F564MGCDBG#21 application, or R5F564MGCDBG#21 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), functional partitioning across PCLKA/PCLKB domains, and validated alternative MCUs for migration or second-sourcing.
Technical Context
The R5F564MGCDBG#21 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units - enabling real-time signal processing in motor control and audio applications. Its clock architecture separates ICLK (up to 120 MHz) from peripheral clocks: PCLKA (120 MHz for ETHERC/USBA/AES), PCLKB (60 MHz for timers/SCI/RIIC), and PCLKC/PCLKD (60 MHz for dual S12AD units).
It integrates dual Ethernet MACs with IEEE 1588 PTP support via EPTPC, three CAN modules (32 mailboxes each), and a dedicated EXDMAC (2 channels) for high-throughput data movement - all coordinated by the Event Link Controller (ELC) to minimize CPU intervention in time-critical sequences like PWM-triggered ADC sampling or RTC-captured timestamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RXv2 32-bit CISC Harvard, 120 MHz max, 240 DMIPS - enables hard real-time loop execution in motion control without external DSP. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP#30 | Same RX64M family, 144-pin LFQFP, 2.5 MB flash, 384 KB SRAM, single Ethernet MAC, no USBA - lacks battery charging USB and second Ethernet channel. | Suitable for cost-sensitive PLC bases without dual-network redundancy or USB peripheral attachment. | Select when footprint size and BOM cost outweigh dual Ethernet and USB charging requirements. |
| R7FA6M2AF3CFP#AA0 | RX72M family, 200 MHz, 2 MB flash, 384 KB SRAM, single Ethernet MAC, no USBA, enhanced FPU, 16-bit A/D (14 ch), no hardware PTP - newer architecture with higher performance but reduced analog channel count. | Better for compute-intensive vision preprocessing or AI inference at edge, less suited for multi-protocol gateway consolidation. | Choose for new designs prioritizing raw MIPS and future-proofing over legacy interface compatibility. |
Compared with R5F564MGCDBG#21, R5F566TEADFP#30 reduces package size and cost but sacrifices dual Ethernet and USB battery charging; R7FA6M2AF3CFP#AA0 increases CPU throughput and adds AI acceleration yet removes one Ethernet MAC and hardware PTP - making R5F564MGCDBG#21 optimal for consolidated industrial gateways needing protocol diversity and precise time synchronization.
