Renesas R5F564MGDDFB#V1

Overview

R5F564MGDDFB#V1 from Renesas is a 120-MHz 32-bit RXv2 core MCU with integrated FPU, 4 MB code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging, CAN (3 channels), and 12-bit A/D (29 total channels). It targets industrial automation controllers requiring deterministic real-time response, secure firmware updates, and multi-protocol connectivity.

For engineers reviewing the R5F564MGDDFB#V1 datasheet, R5F564MGDDFB#V1 pinout, R5F564MGDDFB#V1 application, or R5F564MGDDFB#V1 equivalent, key selection criteria include its 176-pin LFBGA package, dual Ethernet + USB + CAN coexistence, 120 MHz real-time performance, on-chip ECC RAM, and IEC60730 safety features for functional safety certification.

Technical Context

The R5F564MGDDFB#V1 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 240 DMIPS at 120 MHz. It integrates dual independent Ethernet MACs with IEEE 1588 PTP hardware timestamping and dedicated EDMAC channels - one for each ETHERC channel plus one for EPTPC - enabling time-synchronized packet processing without CPU intervention.

Its peripheral clock domain architecture separates ICLK (up to 120 MHz for CPU), PCLKA (up to 120 MHz for Ethernet/USB/AES), PCLKB (up to 60 MHz for timers/SCI), and PCLKC/PCLKD (60 MHz for A/D units) to optimize power/performance trade-offs. The device supports simultaneous operation of USB 2.0 FS host/function with battery charging, three CAN FD-capable ISO11898-1 modules, and SDHI/MMCIF interfaces - all confirmed for the 176-pin variant.

FAQ

What is the maximum operating frequency and core type of the R5F564MGDDFB#V1?

The R5F564MGDDFB#V1 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core. This core delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit, two multiply-and-accumulate units, and support for ultra-compact variable-length instructions. Its 5-stage pipeline and Harvard architecture ensure deterministic real-time execution critical for industrial control applications.

Does the R5F564MGDDFB#V1 support IEEE 1588 Precision Time Protocol?

Yes, the R5F564MGDDFB#V1 includes a dedicated PTP controller (EPTPC) tightly coupled to both Ethernet MACs, enabling hardware timestamping of PTP event messages with sub-microsecond accuracy. This eliminates software-induced jitter and allows synchronization of distributed industrial nodes without CPU overhead - a key requirement for time-sensitive networking in PLCs and motion controllers.

What package type and pin count does the R5F564MGDDFB#V1 use?

The R5F564MGDDFB#V1 uses a 176-pin LFBGA package (PLBG0176GA-A), measuring 13 mm × 13 mm with 0.8 mm ball pitch. This package supports all RX64M features including dual Ethernet, USB 2.0 with battery charging, three CAN interfaces, and 127 general-purpose I/O pins - distinguishing it from smaller 100- or 144-pin variants that omit certain peripherals.

How much on-chip memory does the R5F564MGDDFB#V1 include?

The R5F564MGDDFB#V1 integrates 4 MB of code flash memory with zero-wait-state access at 120 MHz, 64 KB of reprogrammable data flash (100,000 erase/write cycles), 512 KB of high-speed SRAM, 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. This memory hierarchy supports complex real-time OS, secure boot, and data logging in harsh industrial environments.

Is the R5F564MGDDFB#V1 qualified for functional safety standards like IEC60730?

Yes, the R5F564MGDDFB#V1 includes multiple hardware features certified for IEC60730 Class B compliance: oscillation-stop detection, hardware CRC calculator, self-diagnostic A/D converter, register write protection, and a windowed independent watchdog timer (IWDTa). These capabilities reduce software validation burden and accelerate certification for household appliances and medical devices.
