Product Overview
RTL8364NBI‑CG is Realtek industrial‑grade Layer‑2 Gigabit Ethernet switch controller adopting 2+2 architecture: 2 integrated Gigabit PHY ports plus 2 extended MAC interfaces. It supports non‑blocking wire‑speed forwarding, VLAN, QoS and EEE energy‑saving features. Housed in QFN‑88‑EP (10×10 mm) package, it fits compact industrial terminals, mini‑switches and router expansion modules.
Core Advantages
2+2 Port Mixed Architecture
2 native PHY for direct RJ45 connection; 2 extended MAC for external PHY, CPU or fiber modules, optimizing BOM for compact hardware.
Flexible Interface & Configuration
Supports RGMII/SGMII/MII/RMII/GMII; configurable via I2C‑like, SPI or MIIM management interfaces.
Complete L2 Switch & QoS
Non‑blocking forwarding with 2048‑entry MAC table; port‑priority multi‑queue scheduling for stable industrial real‑time traffic.
Industrial‑Grade Low‑Power
-40℃~+85℃ wide temperature range; IEEE 802.3az EEE power‑saving for light‑load operation.

Frequently Asked Questions
Q1: What is the main function of RTL8364NBI‑CG?
A: RTL8364NBI‑CG is a Layer‑2 Gigabit Ethernet switch controller. It features 2 integrated PHY plus 2 extended MAC ports for non‑blocking wire‑speed forwarding in embedded and industrial network hardware.
Q2: What interfaces does RTL8364NBI‑CG support?
A: Extended MAC supports RGMII, SGMII, MII, RMII, GMII. Chip configuration is available via I2C‑like, SPI or MIIM management bus.
Q3: What is the difference between suffix NB‑CG and NBI‑CG?
A: RTL8364NB‑CG is commercial grade (0‑70℃). RTL8364NBI‑CG is industrial grade (-40℃~+85℃). They share identical pinout and package. Do not direct drop‑in replacement without full validation under extreme temperature.
Q4: Can RTL8364NBI‑CG work as a 4‑port all‑PHY switch?
A: No. Only 2 ports have built‑in PHY. The other two MAC ports require external PHY or host MAC, cannot drive RJ45 directly.
Q5: Are there pin‑compatible alternative parts?
A: RTL8364NB‑CG is pin‑to‑pin compatible but commercial temperature only. No cross‑brand fully pin‑compatible equivalent. Register and firmware modification will be needed if switching to other vendors.
Q6: How does RTL8364NBI‑CG compare with RTL8367 series?
A: RTL8364NBI‑CG (QFN‑88,2+2 port) targets compact cost‑sensitive devices. RTL8367 series offer more integrated PHY ports, larger MAC table, bigger package and higher cost for multi‑port switch products.
Q7: Does RTL8364NBI‑CG support energy‑saving function?
A: Yes, it supports IEEE 802.3az EEE, dynamic power adjustment based on link and cable conditions.
Q8: How can I get datasheet, reference schematic or bulk quotation?
A: Please submit our inquiry form for datasheet, reference design, stock check and volume pricing support.
