Description
The STLC4370 is a single chip 802.11b/g WLAN
radio for embedded, low-power and very small
form factor mobile applications. The product
conforms to the IEEE 802.11b and 802.11g
protocols operating in the 2.45GHz ISM
frequency band supporting OFDM data rates of
54, 48, 36, 24, 18, 12, 9, and 6Mbps as well as
CCK data rates of 11 and 5.5Mbps and legacy
data rates of 2 and 1Mbps.
■ Intelligent power control, including 802.11
power save mode
■ Fully integrated Bluetooth coexistence
Applications
■ Cellular phones
■ Personal Digital Assistants (PDA)
■ Portable computers
■ Hand-held data transfer devices
■ Cameras
The STLC4370 is a fully integrated wireless radio
including a ZIF transceiver, RF Synthesizer/VCO,
high-speed data converters, an OFDM/CCK
digital baseband processor, an ARM9-based
MAC and a complete Power Management Unit.
■ Computer peripherals
■ Cable replacement
Host control is provided by a flexible serial
interface (SPI) supporting bit rates of 48Mbps. For
maximum flexibility, the STLC4370 accepts
system reference clock frequencies of 19.2, 26,
38.4 and 40MHz.
A reference design evaluation platform of
hardware and software is provided to system
integrators to rapidly enable wireless connectivity
to mobile platforms.
