Product details
Overview
R5F564MLDDLJ#21 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with integrated FPU, 240 DMIPS performance, 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 CAN interface - designed for industrial networking gateways requiring deterministic real-time control, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F564MLDDLJ#21 datasheet, R5F564MLDDLJ#21 pinout, R5F564MLDDLJ#21 application, or R5F564MLDDLJ#21 equivalent, key selection considerations include its 177-pin TFLGA package (8 × 8 mm, 0.5-mm pitch), dual-channel Ethernet with PTP timestamping, USBA module with 8.5 KB buffer, 21-channel 12-bit ADC unit, and hardware AES/SHA encryption acceleration.
Technical Context
The R5F564MLDDLJ#21 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent clock domains: ICLK up to 120 MHz for CPU execution, and PCLKA/PCLKB up to 120/60 MHz respectively for peripheral operation - enabling concurrent high-speed Ethernet, USB, and real-time control without bus contention.
Its memory subsystem includes 4 MB zero-wait-state code flash with background programming, 512 KB SRAM (no wait states), 32 KB ECC-protected RAM, and 8 KB standby RAM backed by VBATT. The device supports IEEE 1588-2008 PTP via EPTPC linked to ETHERC, and features event-linking (ELC) to synchronize timer-triggered ADC conversions, PWM dead-time generation, and GPIO state changes without CPU intervention.
