Product details
Overview
R5F564MJCDBG#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 (3 channels), and 12-bit A/D (29 total channels). It targets industrial automation controllers requiring deterministic real-time networking, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F564MJCDBG#21 datasheet, R5F564MJCDBG#21 pinout, R5F564MJCDBG#21 application, or R5F564MJCDBG#21 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-channel Ethernet DMA bandwidth (3-channel EDMAC), 177-pin TFLGA package I/O count (127 GPIO), and on-chip AES-256/SHA-256 encryption for secure boot.
Technical Context
The R5F564MJCDBG#21 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. Its clock system 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 two IEEE 1588-compliant Ethernet MACs with dedicated EPTPC hardware timestamping and 3-channel EDMAC (2 for ETHERC, 1 for EPTPC), enabling hardware-accelerated time-synchronized packet processing. The 177-pin TFLGA package provides 127 GPIO with 5-V tolerance on 19 pins, supporting industrial-level signal interfacing without level shifters.
