Freescale Semiconductor
PRELIMINARY
Introduction
terminal manufacturers can tune the chip performance to get the exact balance they opt for when it comes
to power consumption and performance.
1.2
General Description
The high-performance LP1072 baseband processor integrates the IEEE 802.11a/b/g PHY and full MAC
functionality with the industry’s lowest power consumption compared to any baseband processor in the
market.
The LP1072 was designed to target embedded devices and small form factor WLAN devices. Its support
for SDIO and CompactFlash+ host interfaces combined with its ultra low power consumption and small
size make it the optimal solution for mobile devices. It has been designed with a generic RF interface that
lets it interface with virtually any RF components in the market. It has been fully tested to interface with
RF solutions from Maxim and Airoha, thus providing terminal manufacturers with added flexibility in
selecting the most appropriate RF parts based on their application and form factor.
The LP1072’s integrated ADC and DAC reduce the terminal manufacturers' bill of material and overall
system cost. The integrated internal memory eliminates the need for external MAC memory, further
reducing cost and saving valuable board space for small form factor devices.
The LP1072 also provides the highest level of WLAN security by fully supporting WPA and AES.
