Description

The SPWF01SA and the SPWF01SC intelligent Wi-Fi modules represent a plug and play

and standalone 802.11 b/g/n solution for easy integration of wireless Internet connectivity

features into existing or new products.

Configured around a single-chip 802.11 transceiver with integrated PA and an STM32

microcontroller with an extensive GPIO suite, the modules also incorporate timing clocks

and voltage regulators. Two different options exist based on the integrated Flash memory.

The SPWF01Sx.1y orderable parts integrate 1.5 MB of Flash, while The SPWF01Sx.2y

orderable parts integrate 512 kB of Flash.

The module is available either configured with an embedded micro 2.45 GHz ISM band

antenna (SPWF01SA), or with an u.fl connector for external antenna connection

(SPWF01SC).

With low power consumption and small form factor, the modules are ideal for fixed and

mobile wireless applications, as well as challenging battery-operated applications.

The SPWF01Sx.y1 orderable parts are released with an integrated full featured TCP/IP

protocol stack with added web server and additional application service capabilities. The

SW package also includes an AT command layer interface for user-friendly access to the

stack functionalities via the UART serial port. For details, see the user manual UM1695.
