Called SiWG917Y, “the series are shielded modules with a dedicated wireless processing subsystem, an MCU and a security engine,” according to Mouser, which is stocking the parts. “The modules come with radio approvals for the US, Canada and Japan, and follow the relevant EN standards, including EN 300 328 v2.2.2, for conformity with directives and regulations in the EU and UK.”
The RF chain is 2.4GHz only and backed by 160MHz network processor, and the application processor is a 180MHz Arm Cortex-M4 with floating point and 672kbyte of ram.
There are options of 4 or 8Mbyte of on-module flash, or an interface for external flash. 2Mbyte of PSRAM or a PSRAM interface is another option, as is an on-module antenna instead of a pad for an external antenna.
For Wi-Fi, transmission power is +17.5dBm while receive sensitivity is -95dBm. Stand-by current can be as little as 78μA for a 1s listen interval.
The Bluetooth Low Energy radio will work at 1 or 2Mbit/s, or there are 125 or 500kbit/s long-range modes.
SiWN917Y is a similar family of modules that lack the Cortex-M4, the security engine, and any PSRAM option.
Operation is over 3 to 3.63V (1.71 to 3.63V for GPIO) and -40 to +85°C.
