1.PRODUCT OVERVIEW

1.1. General Description

The HF-LPT220 is a fully self-contained small form-factor, single stream, 802.11b/g/n Wi-Fi module,

which provide a wireless interface to any equipment with a Serial interface for data transfer.HF-

LPT220 integrate MAC, baseband processor, RF transceiver with power amplifier in hardware and all

Wi-Fi protocol and configuration functionality and networking stack, in embedded firmware to make a

fully self-contained 802.11b/g/n Wi-Fi solution for a variety of applications.

The HF-LPT220 employs the world's lowest power consumption embedded architecture. It has been

optimized for all kinds of client applications in the home automation, smart grid, handheld device,

personal medical application and industrial control that have lower data rates, and transmit or receive

data on an infrequent basis.

The HF-LPT220 integrates all Wi-Fi functionality into a low-profile, 22x13.5x 3.8mm SMT module

package that can be easily mounted on main PCB with application specific circuits. Also, module

provides built-in antenna, external pad antenna option.

1.1.1 Device Features
