Description
The STLC4560 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 2.45 GHz ISM frequency band supporting OFDM data rates of 54, 48, 36, 24, 18, 12, 9, and 6 Mbit/s as well as CCK data rates of 11 and 5.5 Mbit/s and legacy data rates of 2 and 1 Mbit/s. The STLC4560 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 with integrated PA bias control. In addition some passive components are integrated further reducing the overall reference design cost and size. An external FEM completes a highly integrated chip set solution. Host control is provided by a flexible SPI or SDIO serial interface. The SPI interface supports a maximum clock rate of 48 MHz whereas the 4-bit SDIO supports a maximum clock rate of 25 MHz. For maximum
flexibility, the STLC4560 accepts system reference clock frequencies of 19.2, 26, 38.4 and 40 MHz. A reference design evaluation platform of hardware and software is provided to system integrators to rapidly enable wireless connectivity to mobile platforms.
