Product details
Overview
R5F564MLHDLC#21 from Renesas is a 120-MHz 32-bit RXv2 microcontroller featuring single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (no wait states), 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, secure firmware updates, and deterministic I/O timing.
For engineers reviewing the R5F564MLHDLC#21 datasheet, R5F564MLHDLC#21 pinout, R5F564MLHDLC#21 application, or R5F564MLHDLC#21 equivalent, this MCU delivers verified 240 DMIPS performance, hardware-accelerated AES/SHA encryption, dual-channel Ethernet with PTP timestamping, and 127 GPIOs with 5-V tolerance - critical for evaluating deterministic networking, functional safety (IEC60730), and mixed-signal control in space-constrained embedded designs.
Technical Context
The R5F564MLHDLC#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 Ethernet MACs (ETHERC) with dedicated EPTPC for IEEE 1588 timestamping and EDMAC for descriptor-based DMA offload - supporting simultaneous 10/100 Mbps full/half-duplex operation over MII/RMII interfaces.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL to generate independent clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for high-speed peripherals (Ethernet, USB, AES), and PCLKB up to 60 MHz for timers and ADC - enabling precise peripheral timing isolation without CPU intervention.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F564MLHDLC#21?
The R5F564MLHDLC#21 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiply, and hardware floating-point unit compliant with IEEE-754 single-precision standard - enabling efficient execution of complex control algorithms and protocol stacks without external coprocessors.
Does the R5F564MLHDLC#21 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F564MLHDLC#21 supports IEEE 1588 via its dedicated EPTPC (Precision Time Protocol Controller) block, tightly coupled to both Ethernet MACs (ETHERC). The EPTPC provides hardware timestamping of ingress/egress packets with sub-microsecond resolution, independent of CPU load, and supports PTP slave, master, and boundary clock modes - critical for time-synchronized industrial automation systems.
What are the key differences between the R5F564MLHDLC#21 and the R5F565NEHDFP#30 in terms of connectivity and memory?
The R5F564MLHDLC#21 includes dual IEEE 1588 Ethernet MACs, full-speed USB 2.0 with battery charging (USBA), and 4 MB code flash, whereas the R5F565NEHDFP#30 has only one Ethernet MAC, no USBA module, and 2.5 MB flash. Both share the same 176-pin footprint but differ in package type (LFBGA vs. LQFP) and target application focus - networking density versus cost-optimized edge node deployment.
How does the R5F564MLHDLC#21 meet IEC60730 Class B functional safety requirements?
The R5F564MLHDLC#21 integrates multiple IEC60730-compliant features: oscillation-stop detection, hardware CRC calculator, independent watchdog timer (IWDTa) with configurable window, register write protection, and self-diagnostic A/D converter. These capabilities are documented in Renesas' Functional Safety Manual R01UM0079EJ0200 and enable certified Class B compliance without external safety monitors.
What package type and thermal specifications apply to the R5F564MLHDLC#21?
The R5F564MLHDLC#21 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm body size and 0.5-mm pitch. It is rated for industrial temperature range (–40°C to +85°C, D-version), with thermal resistance θJA = 22.5°C/W (JEDEC JESD51-2) - validated for continuous operation in enclosed control cabinets with natural convection cooling.
