STLC8201
1 FEATURES
■ Tri Mode 802.11a, 802.11g and 802.11b
compliant.
■ AgileRF allows fully automated roaming
between different modes.
■ Implements data rates of 6, 9, 12, 18, 24, 36, 48
and 54 Mbps in 802.11a and 802.11g modes,
using an advanced OFDM processor with
channel equalizer.
■ Implements data rates of 1, 2, 5.5 and 11 Mbps
in 802.11b mode, using advanced RAKE and
decision feedback equalization.
■ Improved PA efficiency using digital pre-
distortion linearization and active bias control.
■ Gain and Phase imbalance correction improves
Rx sensitivity.

data.
■ On-chip 10 bit DAC for analog AGC control.
■ On-chip 10 bit DACs to support DC offset
correction in Zero-IF systems.
■ On-chip 10 bit DAC, and dedicated I/O to
provide transmit power control (TPC).
■ On-chip general purpose 10 bit ADC for power
supply monitoring, PA output power monitoring
or temperature sense.
■ Hardware assisted 40 and 128 bit WEP and
WEP2 (TKIP) engine. Hardware assisted AES
encryption.
■ A low frequency standby clock and advanced
power management extend battery life in
portable equipment.
■ Powerful 32 bit CPU and protocol accelerator
implement the MAC functionality.
■ On-chip system memory removes the need for
external FLASH or SRAM reducing complexity
and cost.

3 DESCRIPTION
The STMicroelectronics STLC8201 wireless LAN
baseband processor is an integrated Medium Ac-
cess Controller and Physical Layer Processor. It
is designed to directly interface with STMicroelec-
tronics's STLC8100 RF transceiver, and with 3rd
party power amplifiers to provide a complete wire-
less LAN solution compliant with IEEE802.11b,
IEEE802.11g and IEEE802.11a.
The STLC8201 includes a unique technology to
deliver dual band multi-mode Access Point with
band interleaving. This allows supporting clients in
both bands without duplicating baseband or RF
functionality.
Powerful security features include WEP, WPA,
WPA2 and AES encryption engines along with
support for 802.1x authentication protocols.
High quality multimedia streaming is enabled with
Quality of Service (QoS) protocols supported by
