The Atech iWEM-1000 is a
complete Wi-Fi and networking solution and includes a 32-bit CPU,
operating system, network stack, crypto accelerator, power
management subsystem, real-time clock and a versatile sensor
interface, allowing it to serve as a light weight networking client
or, with custom software, as a standalone host.
Enabling WiFi Connectivity with
Minimum Software Hardware Resources The iWEM-1000 manages all
networking functions. The Atech standard thin-client application
running on iWEM-1000 handles all networking tasks such as network
scan, join network, establish TCP/IP connection and send/receive
data. Since all networking functions are managed by the iWEM-1000,
wireless Internet connectivity can be added to a system with an 8-
or 16-bit application processor of limited hardware resources
through iWEM-1000 via UART interface.
The only hardware requirement for
the host system to add WiFi connectivity is a simple 3-wire UART
interface. The software integration is simple for iWEM-1000 as
it connects to the configured WiFi network automatically when
it is switched on. The host controller can send and receive
data through UART to IP network if the WiFi network is
available.
Configuring the iWEM-1000 is
easy and can be controlled through a simple ASCii
UART command interface with minimum software resource. This
eliminates the need to port complicated WiFi network drivers onto
the host application processor and results in the fastest time to
market and reduced development costs.
The Atech iWEM-1000 family offers a
a flexible choice of antenna connections, on-board chip antenna,
2.9mm wire, UFL and SMA.
