Product details
Overview
R5F564MGHDFB#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, CAN (3 channels), and 12-bit A/D (29 total channels). It targets industrial networking gateways requiring deterministic real-time control, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F564MGHDFB#31 datasheet, R5F564MGHDFB#31 pinout, R5F564MGHDFB#31 application, or R5F564MGHDFB#31 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + USB + CAN coexistence, 120-MHz deterministic timing, hardware AES/SHA encryption, and IEC60730 safety support for Class B compliance.
Technical Context
The R5F564MGHDFB#31 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. Its clock system supports external crystal (8–24 MHz) or internal HOCO/LOCO, with independent PCLKA (up to 120 MHz) and PCLKB (up to 60 MHz) domains for peripheral timing isolation.
It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP support via EPTPC, three CAN modules compliant with ISO11898-1, and two USB 2.0 FS interfaces - one with battery charging (USBA) and one standard (USBb). The device uses a 177-pin TFLGA package (8 mm × 8 mm, 0.5-mm pitch) and operates from –40°C to +105°C (G-version).
