It targets industrial automation gateways requiring deterministic real-time control, secure connectivity, and high-precision analog sensing.
For engineers reviewing the R5F564MFHDBG#21 datasheet, R5F564MFHDBG#21 pinout, R5F564MFHDBG#21 application, or R5F564MFHDBG#21 equivalent, key selection criteria include its 176-pin LFBGA package, dual Ethernet + USB + CAN coexistence, 120 MHz real-time performance, on-chip AES/SHA encryption, and IEC60730 safety support - all validated for extended temperature (–40°C to +105°C) operation.
Technical Context
The R5F564MFHDBG#21 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. Its memory subsystem includes 4 MB zero-wait-state code flash, 64 KB data flash (100k erase cycles), 512 KB SRAM, and 32 KB ECC-protected RAM.
Peripherals are clocked across four domains: ICLK (up to 120 MHz for CPU), PCLKA (120 MHz for ETHERC/USBA/AES), PCLKB (60 MHz for timers/SCI), and PCLKC/PCLKD (60 MHz for dual S12AD units). The device supports IEEE 1588 PTP via EPTPC linked to ETHERC and features hardware-accelerated cryptographic engines for AES-128/192/256, DES/TDES, and SHA-1/224/256.

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 |
|---|---|---|---|
| R5F565NEHDFB#30 | Same RX65N Group, 144-pin LQFP, 2 MB flash, no USB battery charging, single Ethernet MAC | Suitable for cost-sensitive gateways without dual Ethernet or USB charging requirements | Select when board space allows LQFP and dual Ethernet/USB charging is unnecessary |
| R5F572MHDFB#30 | RX72M Group, 200 MHz, 4 MB flash, single Ethernet, USB HS (480 Mbps), no IEEE 1588 PTP hardware | Better for high-throughput data acquisition but lacks hardware PTP for deterministic networking | Prefer for USB HS camera interfaces where IEEE 1588 sync is not required |

The R5F564MFHDBG#21 operates at up to 120 MHz using the 32-bit RXv2 CPU core, delivering 240 DMIPS performance. It integrates a single-precision IEEE-754 floating-point unit, dual MAC units, and a 5-stage pipeline with variable-length instructions. This architecture enables deterministic real-time execution for industrial control tasks while maintaining ultra-compact code density - critical for maximizing utilization of its 4 MB on-chip flash memory.
Does the R5F564MFHDBG#21 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F564MFHDBG#21 includes dedicated hardware for IEEE 1588 PTP via the EPTPC (Precision Time Protocol Controller) block tightly coupled to both Ethernet MAC channels. It supports hardware timestamping of ingress/egress frames at the PHY interface level, enabling sub-microsecond synchronization accuracy. The EPTPC works with MTU3a and GPTA timers to generate precise time stamps without CPU overhead - a key requirement for R5F564MFHDBG#21 deployments in synchronized motion control and substation automation.
What are the analog capabilities of the R5F564MFHDBG#21, and how are they validated for safety-critical use?
The R5F564MFHDBG#21 integrates two independent 12-bit S12ADC units (8 + 21 channels total) with 0.48 µs conversion time, on-chip sample-and-hold, and self-diagnostic functions that generate internal reference voltages (VREFL0/VREFH0, AVSS1/AVCC1) to verify ADC linearity and offset. It also includes two 12-bit R12DA channels with selectable amplifier/direct output. These features - combined with register write protection and CRC - fulfill IEC60730 Class B requirements, making R5F564MFHDBG#21 suitable for certified medical and industrial safety applications.
How does the R5F564MFHDBG#21 handle USB functionality, and what distinguishes its USBA module?
The R5F564MFHDBG#21 features two USB modules: USBb (standard full-speed) and USBA (full-speed with battery charging). The USBA module - present only in 176/177-pin variants like R5F564MFHDBG#21 - includes 8.5 KB of dedicated RAM, BC1.2-compliant charging detection, and integrated transceiver, eliminating external charger ICs. It supports OTG operation and both bus-powered and self-powered modes - enabling R5F564MFHDBG#21 to serve as a USB host for HMIs or a peripheral for firmware updates without layout complexity.
What package type and environmental rating does the R5F564MFHDBG#21 have, and why is this significant for industrial use?
The R5F564MFHDBG#21 uses the PLBG0176GA-A package: a 176-pin LFBGA measuring 13 mm × 13 mm with 0.8 mm ball pitch. It is rated for –40°C to +105°C (G-version), qualified to industrial temperature standards. This compact, thermally robust package supports high-density PCB layouts while ensuring reliability in harsh environments - such as factory floors or outdoor substations - where thermal cycling and long-term stability are critical for R5F564MFHDBG#21-based equipment.
