LP1072 Advance Information, Rev. 0.3

Freescale Semiconductor

3

PRELIMINARY

•

JTAG Interface for testing and debugging

•

Hardware engines for WEP, TKIP and AES support for less processor load

•

Supports Direct Conversion (Zero-IF) radio architecture, saving RF components thus reducing

BOM cost and simplifying board layout

•

Generic RF interface that lets it work with virtually an WLAN RF components. Currently fully

tested with RF from Maxim and Airoha.

•

Total PHY flexibility in meeting customer requirements by providing software-controlled trade-off

between competing performance metrics
