It supports 802.11b/g/n Wi-Fi connectivity and can be configured using simple commands over the serial port to perform as a client, web server or access point. Simple commands are also used to instruct the module to scan, ping, send, receive, join and leave a network. Wi-Fi System-on-Chip (SoC) component and STMicroelectronics STM32 F-2 Series 32-bit ARM Cortex M3 microcontroller. This STM32 microcontroller hosts the networking application software including the TCP/IP network stack and Inventek’s customized AT Command set firmware.
The ISM4319-M3G-L44 is the newest member of Inventek’s eS-WiFi module family and doubles the available microcomputer memory based on the STM32F205RG. It is footprint compatible with the ISM4319-M3-L44 eS-WiFi module which utilizes the STM32F103RE. This foot print compatibility allows customers to easily migrate for applications with larger flash and/or RAM memory requirements. ST’s large on-chip memory density also allows Inventek the flexibility of implementing additional network features in future firmware upgrades.
"The ISM4319-M3G-L44 is an ideal solution for adding connectivity to any product because of its rich feature set coupled with its easy-to-use command set. Customers have been able to demonstrate connectivity in their systems within hours and to complete integration within days. Wi-Fi connectivity by adding a layer of firmware that controls the wireless functionality through simply AT Commands running on a host processor. The STM32 Microcontroller provides a very flexible architecture for Inventek’s eS-WiFi family of embedded modules and allows for the scalability needed to meet broad market requirements. The key combination of processing power, on-chip memory, peripheral support and cost provided the exact mix of features that enables this eS-WiFi module:” said Arnaud Julienne, Director of GC&SA MMS Product Group at STMicroelectronics.
The ISM4319-M3G-L44 eS-WiFi module development kits are available now from inventory for $159 and may be ordered from the Inventek Systems Store.
