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.

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.

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.
