Product Overview

1.1. Introduction
MegaChips provides a complete Wi-Fi HaLow connectivity solution. The MBWMO000002 is a fully integrated Wi-Fi HaLow® modules with long-range, low-power consumption and superior RF performance, featuring the MM6108 Wi-Fi HaLow SoC.
The MBWMO000002 is designed in compliance with the IEEE 802.11ah standard, supporting data rates up to 32.5 Mbps with programmable operation between 850 MHz and 950 MHz.
This module includes ultra-long-reach PA, high linearity LNA, T/R switch, 32 MHz crystal oscillator and it has been designed for a simplified Wi-Fi HaLow connection to an external host for applications in which a customer wants to merely replace their prior RF technology with a Wi-Fi HaLow connection while leveraging the latest WPA3 security protocol.
Battery-operated applications are supported by a combination of features which are inherently supported by the module. The IEEE 802.11ah standard provides for extended sleep times for battery-operated Stations (STAs or client devices), with longer duration than other prior |IEEE 802.11a/b/g/n/ac generations.
It also allows longer extended maximum idle times for clients to conserve energy without being removed from the access point’s (AP’s) list of associated devices.

Functional Description

The following sections describe the functions of the MBWMO000002 device.
3.1. Power Management
Module power is derived from a 1.8 to 3.6 V supply provided on pin VBAT. A 3.3V supply is provided on pin VDD_FEM to power the on-board ultra-long-range PA.
VDDIO sets the 10 voltage of the MM6108 and should be connected to the same power supply as the host MCU.
3.2. Digital Interfaces
All unused digital IO pins must be pulled up or down to ensure they do not float. Failure to do so, will result in a higher leakage current on the VDDIO supply.
Please refer to the MM6108 chip datasheets for a description of the supported peripheral interfaces.

Handling and Storage

The MM610x-MF08251 class of modules are a moisture sensitive device rated at Moisture Sensitive Level 3 (MSL3) per IPC/JEDEC J-STD-20.
After opening the moisture sealed storage bag, modules that will be subjected to re flow solder or other high temperature processes must be:

Mounted to a circuit board within 168 hours at factory conditions (<30°C and <60% RH)
OR
Continuously stored per IPC/JEDEC J-STD-033

Modules that have been exposed to moisture and environmental conditions exceeding packaging and storage conditions MUST be baked before mounting according to IPC/JEDEC J-STD-033. Failure to meet packaging and storage conditions will result in irreparable damage to modules during solder re flow.
