Renesas R5F564MFGDFP#31

Overview

R5F564MFGDFP#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 v2.0B - deployed in industrial gateways requiring deterministic real-time control, secure connectivity, and multi-protocol edge processing.

For engineers reviewing the R5F564MFGDFP#31 datasheet, R5F564MFGDFP#31 pinout, R5F564MFGDFP#31 application, or R5F564MFGDFP#31 equivalent, key selection criteria include dual Ethernet + PTP timestamping capability, on-chip AES/SHA encryption, 127 GPIO with 5-V tolerance, 12-bit dual A/D with self-diagnostic, and support for IEC 60730 Class B functional safety compliance.

Technical Context

The R5F564MFGDFP#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - delivering 240 DMIPS at 120 MHz while supporting IEEE-754 single-precision floating-point operations and two MAC units. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated oscillator, enabling independent domain clocks (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Peripheral subsystems are tightly coupled via Event Link Controller (ELC) for zero-CPU-intervention triggering: MTU3/GPT timers generate A/D start triggers, SCIg/SCIh support LIN and smart-card modes, and ETHERC+EPTPC+EDMACa form a hardware-accelerated time-sensitive networking (TSN)-ready stack with cut-through frame transfer and Magic Packet wake-on-LAN.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F564MFGDFP#31?

The R5F564MFGDFP#31 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance. This is achieved by the RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiply, and dual MAC units - verified in Renesas R01DS0173EJ0120 Rev.1.20 Section 1.1. The DMIPS figure reflects Dhrystone 2.1 benchmark results measured at 120 MHz with cache enabled.

Does the R5F564MFGDFP#31 support IEEE 1588 Precision Time Protocol hardware acceleration?

Yes, the R5F564MFGDFP#31 includes a dedicated PTP controller (EPTPC) linked directly to its dual Ethernet MAC (ETHERC) modules. It provides hardware timestamping of ingress/egress Ethernet frames with sub-100 ns resolution, enabling transparent clock and boundary clock implementations per IEEE 1588-2008 - confirmed in Section 1.1 and Figure 1.3 of R01DS0173EJ0120 Rev.1.20.

How many analog-to-digital converter channels does the R5F564MFGDFP#31 provide, and what is their resolution?

The R5F564MFGDFP#31 integrates two independent 12-bit A/D converters: S12ADC Unit 0 with 8 channels and Unit 1 with 21 channels. Resolution is configurable at 8-, 10-, or 12-bit per channel, with minimum conversion times of 0.42 µs (8-bit), 0.45 µs (10-bit), and 0.48 µs (12-bit) - detailed in Table 1.1 (page 9) and Section 21.3 of R01DS0173EJ0120 Rev.1.20.

What package type and pin count does the R5F564MFGDFP#31 use?

The R5F564MFGDFP#31 uses the PLBG0176GA-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 13 mm × 13 mm with 0.8-mm ball pitch. This matches the "176-pin LFBGA" variant defined in Table 1.2 of R01DS0173EJ0120 Rev.1.20 and supports all peripheral functions including dual Ethernet, USB, and 127 GPIO.

Is the R5F564MFGDFP#31 qualified for extended temperature operation?

Yes, the R5F564MFGDFP#31 is rated for –40°C to +105°C operation (G-version), as specified in Section 1.1 "Operating temp. range" of R01DS0173EJ0120 Rev.1.20. This qualification covers full functionality of CPU, flash, SRAM, Ethernet, USB, CAN, and A/D peripherals across the entire range - making it suitable for under-hood automotive and outdoor industrial deployments.
