Flexible hardware settings are provided to configure the various operating modes of the chip. The RTL8208 consists of 8 separate and independent channels. Each channel consists of an RMII/SMII/SS-SMII interface to MAC controller, and hardware pins are used to configure the interface for RMII, or SMII, or SS-SMII mode. In RMII mode, another hardware pin is used to set port-pair loop mode (PP-LPBK mode), which can extend physical transmission length or perform physical media transport operations without any switch controller. In addition, the RTL8208 features very low power consumption, as low as 1.8 W (max.). Additionally, pin-outs are designed to provide optimized direct routing can be implemented, which simplifies the layout work and reduces EMI noise issues.3. Block Diagram4.

(Read/Write)1=Full duplex operation.0=Half duplex operation.RW 10.[7:0] Reserved 0 *SMI: Serial Management Interface , which is composed of MDC,MDIO, allows MAC to manage PHY.Reset – In order to reset the RTL8208 by software control, a ‘1’ must be written to bit 15 using an SMI write operation. The bit clears itself after the reset process is complete, and does not need to be cleared using a second SMI write. Writes to other Control register bits will have no effect until the reset process is completed, which requires approximately 1us. Writing a ‘0’ to this bit has no effect. Because this bit is self clearing after a few cycles from a write operation, it will return a ‘0’ when read. Loopback – The RTL8208 may be placed into loopback mode by writing a ‘1’ to bit 14. Loopback mode may be cleared either by writing a ‘0’ to bit 14 or by resetting the chip. When this bit is read, it will return a ‘1’ when the chip is in software-controlled loopback mode, otherwise it will return a ‘0’.Speed Selection – If Auto-negotiation is enabled, this bit has no effect on the speed selection. However, if Auto-negotiation is disabled by software control, the operating speed of the RTL8208 can be forced by writing the appropriate value to bit 13. Writing a ‘1’ to this bit forces 100Base-X operation, while writing a ‘0’ forces 10Base-T operation. When this bit is read, it returns the value of the software controlled forced speed selection only.Auto Negotiation Enable – Default Auto Negotiation enable for all TP ports and disable for FX ports. Auto-negotiation can be disabled by either software control to set 0.12=0.Power Down – The RTL8208 supports a low power mode which is intended to decrease power consumption. Writing a ‘1’ will enable power down mode, and writing a ‘0’ will return the RTL8208 to normal operation. When read, this register will return a ‘1’ when in power down mode, and a ‘0’ during normal operation.Isolate – Each individual PHY may be isolated from its MII by writing a ‘1’ to bit 10. All MII outputs will be tri-stated and all MII inputs will be ignored. Since the MII management interface is still active, the isolate mode may be cleared either by writing a ‘0’ to bit 10 or by resetting the chip. When this bit is read, it will return a ‘1’ when the chip is in isolate mode, and a ‘0’ during normal operation.Restart Auto Negotiation – Bit 9 is a self-clearing bit that allows the Auto-negotiation process to be restarted, regardless of the current status of the Auto-negotiation state machine. In order for this bit to have an effect, Auto-negotiation must be enabled. Writing a ‘1’ to this bit restarts Auto-negotiation while writing a ‘0’ to this bit has no effect. When this bit is read, it will always return a ‘0’.Duplex Mode – By default, the RTL8208 powers up in half duplex mode. The chip can be forced into full duplex mode by writing a ‘1’ to bit 8 while Auto-negotiation is disabled. Half duplex mode can be resumed either by writing a ‘0’ to bit 8 or by resetting the chip. When Nway is enabled, this bit reflects the results of the Auto-negotiation, and is in a read only mode. When Nway is disabled, this bit can be set through the SMI, and is in a read/write mode. When 100FX is enabled, this bit can be set through the SMI or FX_DUPLEX pin and is in a read/write mode.Reserved Bits – All reserved MII register bits must be written as ‘0’ at all times. Ignore the RTL8208 output when these bits are read.6.2 Register1: StatusReg. bit Name Description Mode Default 1.15 100Base_T4 0 = no 100Base-T4 capability.

Any reads to this bit will return a ‘0’.100Base_TX_FD – The RTL8208 is capable of operating in 100Base-TX full duplex mode.100Base_TX_HD – The RTL8208 is capable of operating in 100Base-TX half duplex mode.10Base_T_FD – The RTL8208 is capable of operating in 10Base-T full duplex mode.10Base_T_HD – The RTL8208 is capable of operating in 10Base-T half duplex mode.Reserved – Ignore the output of the RTL8208 when these bits are read.MF Preamble Suppression – Management Frame Preamble Suppression is permanently set in the RTL8208, allowing subsequent MII management frames to be accepted with or without the standard preamble pattern. Only two preamble bits are required between successive management commands, instead of the normal 32, however, a minimum of 32 preamble bits are required for the first SMI read/write transaction after reset. One idle bit is required between any two management transactions (as defined in IEEE802.3u spec). Reads of this bit will always return a ‘1’.Auto-negotiate Complete – Bit 5 will return a ‘1’ if the Auto-negotiation process has been completed and the contents of registers 4 and 5 are valid.Remote Fault – When link partner detect far-end fault, it would send far-end indication stream pattern. When RTL8208 receive this pattern, set Reg1.4=1.Auto-Negotiation Ability – The RTL8208 is capable of performing IEEE Auto-negotiation, and will return a ‘1’ when bit 4 is read, regardless of whether or not the Auto-negotiation function has been disabled.Link Status – The RTL8208 will return a ‘1’ on bit 2 when the link state machine is in Link Pass, indicating that a valid link has been established. Otherwise, it will return ‘0’. When a link failure occurs after the link pass state has been entered, the Link。

Systems that exceed the recommended maximum power dissipation in the end product may require additional thermal enhancements. Ambient temperature (T A) varies with the end application and product design. The critical factor that affects reliability and functionality is T J, the junction temperature, not the ambient temperature. Hence, care should be taken to keep T J within the specified limits. T case should be measured to estimate the operating junction temperature T J. T case is normally measured at the center of the package top-side surface. The thermal application report Semiconductor and IC Package Thermal Metrics helps to understand the thermal metrics and definitions.26Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: TMS320F2810TMS320F2810-Q1TMS320F2811TMS320F2811-Q1TMS320F2812TMS320F2812-Q1。

E18系列模块采用美国德州仪器公司原装进口CC2530射频芯片，芯片内部集成了8051单片机及无线收发器，部分模块型号内置PA功率放大器增加通信距离。

出厂自带固件基于ZigBee3.0协议实现的串口数据透传，支持ZigBee3.0协议下各种指令命令。

经实测，对市面上大多数ZigBee3.0产品有着非常良好的兼容性。

1.2ZigBee 3.0优势E18系列模块固件基于Z-Stack3.0.2协议栈（ZigBee 3.0），该版本为CC2530/CC2538系列芯片最优协议栈，因此我司也此基础上做了许多优化，确保系统长期稳定运行。

ZigBee3.0与早前版本的应用方式区别：1.组网方式发生变化：ZigBee 3.0取缔了一上电就组网的方式，而是根据实际需要进行组网。

任何设备在出厂状态下是无网络状态，协调器需要运行“formation”（调用bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION)）来新建网络，然后再运行"Steering"(调用bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_STEERING))打开网络，打开网络默认时间180秒，可通过广播"ZDP_MgmtPermitJoinReq"的方式将打开网络提前关闭。
