Surging Demand for Network Interconnection

With the close integration of cutting-edge technologies such as the Internet of Things, artificial intelligence, and big data, and their deep penetration into various social fields like smart homes, smart factories, and smart security, the demand for stable, high-speed, and reliable network connections is experiencing explosive growth. Smart home devices need to upload data to the cloud instantly, smart factories achieve seamless collaboration among devices through the network, and smart security systems must ensure continuous and stable data transmission. In this context, the quality of network connection directly affects the operational efficiency of various fields and the user experience. A high-performance Ethernet controller chip has become crucial.

Corebai CBM1001A-Q Ethernet MAC Controller

The CBM1001A-Q is an Ethernet controller chip integrating the 10/100M PHY and MAC layers, with 16K bytes of built-in SRAM providing efficient cache space for data processing. It supports 8-bit and 16-bit data interfaces, can easily adapt to different processors, and can operate stably in a voltage environment of 3.3V - 5V, greatly enhancing the flexibility of applications.

1. Product Advantages

l Powerful Compatibility and Wide Adaptability: It supports multiple Ethernet standards, ranging from UTP3, 4, 5 10Base - T to UTP5 100Base - TX, meeting the requirements of different network environments. Its HP Auto - MDIX detection function can automatically identify the type of network cable connection. Whether it is a crossover cable or a straight cable, it can be used plug-and-play, thus greatly simplifying the cumbersome process of network deployment.

l Stable Transmission and Smooth Guarantee: It supports the back pressure flow control mode in half-duplex and the IEEE802.3x flow control mode in full-duplex. When the network is congested, the flow control mechanism and the product process control system can prevent data loss and ensure the stability of data transmission. For example, in a smart factory, when a large number of devices transmit data simultaneously, these mechanisms can ensure the reliable transmission of production instructions and device status information, avoiding production interruptions due to data congestion.

l Low Power Consumption and High Performance, Long Endurance: It has low-power operation modes such as Power reduced mode and Power down mode, with a standby power consumption as low as 7mA. For smart home devices, the low-power consumption feature not only significantly extends the battery life of the devices but also does not reduce their network connection performance at all, truly achieving a harmonious unity of energy conservation and high efficiency.

l Remote Wake-up, Ready at Any Time: It supports remote wake-up functions such as wake-up frames, link status changes, and magic packet events. When a smart security camera is in a dormant state, once an abnormal situation triggers a wake-up event, the camera can quickly start up, connect to the network, and transmit surveillance footage in a timely manner to ensure home security.

l Multi-function Integration, Comprehensive Protection: It has a built-in 3.3V to 2.5V voltage regulator to provide a stable power supply for internal circuits of the chip, ensuring the stable operation of the chip. It supports the generation and checking of IP/TCP/UDP checksums to ensure the accuracy of data transmission, which is crucial in scenarios with extremely high requirements for data accuracy, such as financial data transmission. It supports the automatic loading of vendor ID and product ID from EEPROM. At the same time, the optional EEPROM configuration further enhances the flexibility of the chip, allowing users to easily make personalized configurations according to actual needs.
