Four low-power IoT wi-fi solutions announced by Microchip Technology
Microchip Technology, a provider of microcontroller, mixed-signal, analog and Flash-IP solutions, has announced four compact, low-power, integrated solutions that allow Wi-Fi and networking capability to be embedded into any device, including Internet of Things (IoT) applications.
The four modules, all of which provide solutions for 802.11b/g/n, include:
The RN1810 and RN1810E:
Stand-alone, surface-mount WiFly radio modules that include a TCP/IP stack, cryptographic accelerator, power management subsystem, 2.4 GHz 802.11b/g/n-compliant transceivers and 2.4 RF power amplifier.
They can be paired with any microcontroller and configured using ASCII commands. WiFly provides designers with a data pipe for sending data over a Wi-Fi network, requiring no prior Wi-Fi experience to get a product connected. Once configured, the device automatically accesses a Wi-Fi network and sends and receives serial data.
The RN1810 has an integrated PCB antenna and the RN1810E supports an external antenna.
Wi-Fi modules that interface with Microchip's PIC32 microcontrollers and support Microchip's MPLAB Harmony integrated software framework with a TCP/IP stack that can be downloaded here.
The modules connect to the microcontroller via a 4-wire SPI interface and provide a solution for low-power, low-data-rate Wi-Fi sensor networks, home automation, building automation and consumer applications.
The MRF24WN0MA has an integrated PCB antenna while the MRF24WN0MB supports an external antenna.
"This new family of Wi-Fi modules provides design flexibility for a broad range of consumer, industrial retail, and utility/smart energy applications," Clayton Pillion, worldwide marketing manager of Microchip's Wireless Solutions Group, said in a statement.
"They greatly streamline the integration and configuration process, allowing designers to concentrate instead on the host product."
Each module is FCC (USA), IC (Canada) and ETSI (Europe) certified and supports multiple networking features including TCP/IP, Internet Protocol Version 6 (IPv6) and Secure Sockets Layer/Transport Layer Security (SSL/TLS 1.2).
