Overview

R5F564MFHDFC#31 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, and CAN interface - designed for industrial networking gateways requiring deterministic real-time control, secure firmware updates, and multi-protocol connectivity.

For engineers reviewing the R5F564MFHDFC#31 datasheet, R5F564MFHDFC#31 pinout, R5F564MFHDFC#31 application, or R5F564MFHDFC#31 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), confirmed peripheral channel counts, functional differences among RX64M variants, and two validated alternative MCUs for migration or second-sourcing.

Technical Context

The R5F564MFHDFC#31 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and memory protection unit (MPU) - enabling deterministic real-time execution in safety-critical applications. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP support via EPTPC and dedicated EDMAC channels, plus USBA with 8.5 KB on-chip RAM for battery-charging-capable USB host/device operation.

Its clock system combines external crystal input (8–24 MHz), internal HOCO/LOCO oscillators, and PLL-based frequency synthesis to drive ICLK at 120 MHz and independent peripheral clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz). The device supports four low-power modes, RTC with battery backup, and hardware-accelerated AES/SHA/DES encryption - meeting IEC 60730 Class B requirements through oscillation-stop detection, CRC, IWDTa, and A/D self-diagnostic functions.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F564MFHDFC#31?

The R5F564MFHDFC#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS (Dhrystone MIPS) performance. This is achieved using the RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiply, and integrated single-precision IEEE-754 floating-point unit - enabling efficient execution of real-time control algorithms and protocol stacks without external coprocessors.

Does the R5F564MFHDFC#31 support IEEE 1588 Precision Time Protocol (PTP)?

Yes, the R5F564MFHDFC#31 supports IEEE 1588-2008 PTP through its integrated EPTPC (PTP Controller for Ethernet) block, which connects directly to both Ethernet MAC channels. Hardware timestamping occurs at the MAC layer with nanosecond resolution, and the EPTPC handles PTP message parsing, correction field calculation, and clock synchronization - eliminating software latency and jitter in time-critical industrial networks.

What package type and pin count does the R5F564MFHDFC#31 use?

The R5F564MFHDFC#31 uses the PLQP0176KB-A package: a 176-ball Low-Profile Quad Flat Package (LFBGA) with 24 × 24 mm body size and 0.5-mm ball pitch. This package supports all RX64M peripherals including dual Ethernet PHY interfaces, USBA, CAN, QSPI, SDHI, and 127 general-purpose I/O pins with 5-V tolerance on 19 pins.

How much on-chip flash and RAM does the R5F564MFHDFC#31 include?

The R5F564MFHDFC#31 integrates 4 MB of on-chip code flash memory with zero-wait-state operation at 120 MHz, and 512 KB of high-speed SRAM with no wait states. It also includes 32 KB of ECC-protected RAM (SEC-DED), 64 KB of reprogrammable data flash (100,000 write cycles), and 8 KB of standby RAM backed by VBATT for RTC and context retention during deep sleep.

Is hardware encryption available on the R5F564MFHDFC#31, and what algorithms does it support?

Yes, the R5F564MFHDFC#31 includes optional hardware-accelerated encryption supporting AES (128/192/256-bit keys), DES (56-bit) and T-DES (3 × 56-bit), and SHA-1, SHA-224, SHA-256, and HMAC variants. These engines operate independently of the CPU, enabling secure boot verification, encrypted firmware updates, and authenticated data logging - all critical for IEC 60730 Class B certification and secure IoT deployments.
