Renesas R5F564MLHGFP#V1

Overview

R5F564MLHGFP#V1 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, CAN (3 channels), and 12-bit A/D (29 total channels). It targets industrial automation controllers requiring deterministic real-time networking, secure firmware updates, and multi-protocol connectivity.

For engineers reviewing the R5F564MLHGFP#V1 datasheet, R5F564MLHGFP#V1 pinout, R5F564MLHGFP#V1 application, or R5F564MLHGFP#V1 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + PTP timing accuracy, on-chip AES/SHA encryption, 32-KB ECC RAM for safety-critical data, and support for IEC60730 Class B compliance via built-in self-test functions.

Technical Context

The R5F564MLHGFP#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 dedicated EDMAC (3-channel) and EPTPC blocks compliant with IEEE 1588-2008 for sub-microsecond time synchronization in industrial Ethernet applications.

Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL to generate ICLK up to 120 MHz, PCLKA up to 120 MHz (for Ethernet/USB/AES), and PCLKB up to 60 MHz (for timers/ADC). The device supports four low-power modes and battery-backed RTC operation via VBATT pin.

FAQ

What is the maximum operating frequency and performance of the R5F564MLHGFP#V1?

The R5F564MLHGFP#V1 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS using the RXv2 CPU core. Its single-precision IEEE-754 floating-point unit, dual multiply-accumulate units, and 5-stage pipeline enable deterministic real-time processing for motion control and protocol stack handling. This performance level is validated in the R01DS0173EJ0120 datasheet Rev.1.20.

Does the R5F564MLHGFP#V1 support IEEE 1588 Precision Time Protocol?

Yes, the R5F564MLHGFP#V1 integrates a dedicated PTP controller (EPTPC) linked to both Ethernet MACs, providing hardware timestamping compliant with IEEE 1588-2008. It supports one-step and two-step clock synchronization, transparent clock functionality, and sub-microsecond timestamp resolution-essential for industrial Ethernet determinism. This is confirmed in Section 1.1 and Table 1.1 of the official datasheet.

What package type and pin count does the R5F564MLHGFP#V1 use?

The R5F564MLHGFP#V1 uses a 177-ball TFLGA package (PTLG0177KA-A) measuring 8 mm × 8 mm with 0.5-mm pitch. It provides 127 general-purpose I/O pins, including 19 with 5-V tolerance, and dedicated signal groups for dual Ethernet, USB, CAN, and high-speed serial interfaces. Package details appear on page 1 of R01DS0173EJ0120.

How does the R5F564MLHGFP#V1 handle functional safety compliance?

The R5F564MLHGFP#V1 includes multiple IEC60730 Class B compliance features: oscillation-stop detection, hardware CRC calculation, independent watchdog timer (IWDTa) with window function, A/D converter self-diagnostic, and register write protection. These are documented in the "Useful functions for IEC60730 compliance" section of the datasheet and enable certified safety firmware design without external components.

Can the R5F564MLHGFP#V1 execute secure firmware updates in the field?

Yes, the R5F564MLHGFP#V1 supports secure over-the-air updates via its background programming/erasing (BGO) capability for both code and data flash, combined with on-chip AES/SHA cryptographic acceleration. This allows authenticated, encrypted firmware images to be validated and written without halting application execution-critical for remote industrial equipment maintenance.
