Wireless LAN Medium Access Controller
The Intersil HFA3841 Wireless LAN
Medium Access Controller is part of the
PRISM® Enterprise 2.4GHz WLAN
chip set. The HFA3841 directly
interfaces with the Intersil HFA386x
family of Baseband Processors, offering a complete end-to-
end chip set solution for wireless LAN products. Protocol and
PHY support are implemented in firmware to allow custom
protocol and different PHY transceivers.
The HFA3841 is designed to provide maximum performance
with minimum power consumption. External pin layout is
organized to provide optimal PC board layout to all user
Firmware implements the full IEEE 802.11 Wireless LAN
MAC protocol. It supports BSS and IBSS operation under
DCF, and operation under the optional Point Coordination
Function (PCF). Low level protocol functions such as
RTS/CTS generation and acknowledgement, fragmentation
and de-fragmentation, and automatic beacon monitoring are
handed without host intervention. Active scanning is
performed autonomously once initiated by host command.
Host interface command and status handshakes allow
concurrent operations from multi-threaded I/O drivers.
Additional firmware functions specific to access point
applications are also available.
Designing wireless protocol systems using the HFA3841 is
made easier with the availability of evaluation board,
firmware, software device drivers, and complete
