ZD1211 is a compact, high security, low power and high performance solution for versatile WLAN applications.

ZD1211 integrates WLAN MAC controller, base-band processor and USB 2.0 interface in single chip. The integrated USB 2.0 controller reduces the cost and design complexity. No extra memory device is needed. It can fit into small PCB form factor.

There is Micro-Controller inside the chip. This allows the flexibility to software change the operation scenario to adapt in USB or WLAN compatibility issues.
Integrated standard compliant hardware security engine to improve the performance in security mode.

The hardware engine includes the WEP64, WEP128, WEP256, AES-CCM, TKIP that comply Wi-Fi and IEEE 802.11 defined standards.

ZD1211 considers the power management issues in WLAN applications and USB certification. It provides the lower power consumption for WLAN in power saving mode and USB suspend mode.

ZD1211 can operate in the mode of station and access point. It can fit to feature demand in different WLAN applications.

Optional 16 bit host interface is provided. This interface can connect to the memory bus of host processor . It will be useful in embedded application.
