Product details
Overview
R5F564MGHDLK#21 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 120 MHz (240 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging support, and integrated 12-bit A/D and D/A converters - deployed in industrial automation gateways requiring real-time protocol handling and secure firmware execution.
For engineers reviewing the R5F564MGHDLK#21 datasheet, R5F564MGHDLK#21 pinout, R5F564MGHDLK#21 application, or R5F564MGHDLK#21 equivalent, this MCU delivers deterministic real-time control with hardware-accelerated crypto (AES-128/192/256, SHA-256), dual Ethernet for redundancy or time-synchronized I/O, and robust functional safety features aligned with IEC 60730.
Technical Context
The R5F564MGHDLK#21 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet MACs with IEEE 1588 PTP hardware timestamping and dedicated EDMAC channels for zero-copy frame processing.
Its memory subsystem includes 4 MB no-wait-state flash supporting background programming, 512 KB SRAM with no wait states, 32 KB ECC-protected RAM (SEC-DED), and 8 KB standby RAM backed by VBATT. Clocking uses PLL multiplication of HOCO (16–20 MHz) or external crystal (8–24 MHz) to achieve 120 MHz ICLK.
