## 1 Product Overview

### 1.1 Introduction

Morse Micro provides a complete Wi-Fi HaLow connectivity solution. The MM6108-MF08651-US is a fully integrated Wi-Fi HaLow® module featuring the MM6108 Wi-Fi HaLow SoC. It offers long-range, low-power consumption, and superior RF performance.

The MM6108-MF08651-US module is designed in compliance with the IEEE 802.11ah standard. It supports data rates up to 32.5 Mbps and has programmable operation between 902 MHz and 928 MHz.

This module includes an ultra-long-reach PA, a high linearity LNA, a SAW filter, a T/R switch, and a 32 MHz crystal oscillator. It has been designed for a simplified Wi-Fi HaLow connection to an external host for applications where customers want to replace their prior RF technology with a Wi-Fi HaLow connection while using the latest WPA3 security protocol.

Battery-operated applications are supported by a combination of features inherently supported by the module. The IEEE 802.11ah standard provides extended sleep times for battery-operated stations (STAs or client devices), with longer durations than other prior IEEE 802.11a/b/g/n/ac generations. The standard 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.

## 3 Functional Description

The following sections describe the functions of the MM6108-MF08651-US module.

### 3.1 Block diagram

![Figure 2: Functional Block Diagram](/files/033e4fa050465109eccee58159788185785f0f76)

*Figure 2: Functional Block Diagram*

***

### 3.2 Power supply requirements

MM6108-MF08651-US module power is derived from a 3.0 to 3.6V supply on the VBAT pin and a 3.0 to 4.3V supply on the VDD\_FEM pin. VBAT powers the module’s internal circuitry, while VDD\_FEM powers the onboard ultra-long-range power amplifier. The module's transmitter power output can be increased by raising the supply voltage on the VDD\_FEM pin to 4.3V, although this will increase overall power consumption.

VDDIO sets the IO voltage of the MM6108, which should be connected to the same power supply as the host MCU. The VDDIO voltage must be between 1.62V and 3.6V and must not exceed the voltage applied to VBAT.

***

### 3.3 SDIO host requirements

When selecting a CPU host to interface with the MM8108-MF08651 module via the SDIO interface, ensure the host supports SDIO 2.0 with SDIO clock speeds of up to 50 MHz. Slower clock speeds will impact the maximum achievable throughput.

The SDIO data and command lines should be pulled up with 10k-100k resistors per the SDIO 2.0 specification.

Most applications will benefit from the module's power-saving features. Two GPIOs, set as CMOS outputs, are required to drive the RESET and WAKE signals. A third GPIO, set as a CMOS input, is needed to receive the BUSY signal from the module.

In applications where the module must always be on, and the power-saving features can not be used, such as access points, the WAKE pin can be fixed to VBAT, reducing the need for GPIOs on the host processor to only one.

A schematic diagram detailing the recommended SDIO host interface circuit using the module’s power-saving features is shown below:

![Figure 3: Recommended SDIO host interface circuit using power-saving features](/files/4d4d45a507f94aa3170dda5f322322865ba57892)

*Figure 3: Recommended SDIO host interface circuit using power-saving features*

A schematic diagram detailing the recommended SDIO host interface circuit for always-on applications is shown below:

![Figure 4: Recommended SDIO host interface circuit for always-on applications](/files/1961d39ca34e6704826a15119af4922ab7b734bc)

*Figure 4: Recommended SDIO host interface circuit for always-on applications*

### 3.4 SPI host requirements

When selecting a CPU host to interface via SPI to the MM6108-MF08651-US module, consider the following recommendations to achieve the best throughput:

* The host should support level-triggered interrupts.
* The host should support full-duplex SPI mode.
* The host should support DMA-backed transactions on the SPI bus.

Standard SPI can achieve up to 25 Mbps at 50 MHz, but this will be significantly reduced without DMA support. For example, an SPI interface with an 8-byte buffer per transaction might only achieve 2 Mbps throughput on the SPI bus.

Most applications will benefit from the module's power-saving features. Two GPIOs, set as CMOS outputs, are required to drive the RESET and WAKE signals. A third GPIO, set as a CMOS input, is needed to receive the BUSY signal from the module.

In applications where the module must always be on, and the power-saving features can not be used, such as access points, the WAKE pin can be fixed to VBAT, reducing the need for GPIOs on the host processor to only one.

***

A schematic diagram detailing the recommended SPI host interface circuit using the module’s power-saving features is shown below:

![Figure 5: Recommended SPI host interface circuit using power-saving features](/files/4912417655e97c2fc19c434044bc5da0dcd0f93c)

*Figure 5: Recommended SPI host interface circuit using power-saving features*

***

A schematic diagram detailing the recommended SPI host interface circuit for always-on applications is shown below:

![Figure 6: Recommended SPI host interface circuit for always-on applications](/files/f0ce0e5a3be6d80d0c13fbc59cb226d2e3fb7691)

*Figure 6: Recommended SPI host interface circuit for always-on applications*

### 3.5 Digital interfaces

All unused digital IO pins must be pulled up or down to prevent floating pins. Failure to do so will result in a higher leakage current on the VDDIO supply.

***

### 3.6 Sleep/Wake Sequencing

#### 3.6.1 Host initiates wake sequence

![Figure 7: Host-initiated wake sequence diagram](/files/bfe47bbe7484b8e66a9953241648e8f37c668841)

*Figure 7: Host-initiated wake sequence diagram*

1. The driver raises the wake pin and waits for a static period of 10 ms before initializing the shared communication bus and initiating host interface activity. On MM6108, this period is typically 10 ms.
2. After completing communication, the driver will wait a static period, b, before lowering the wake pin (assuming no further communication has occurred). Depending on the nature of the communication (802.11 data vs. commands), this period can range from 5 to 90ms.
3. After the wake pin has fallen, the MM6108 will wait for a period, c, before initiating hardware sleep. This dynamic period will differ depending on the power-saving protocol and other chip-specific factors.

***

#### 3.6.2 MM6108-MF08651 initiates wake sequence with host interface disabled

![Figure 8: Module-initiated wake sequence with host interface disabled diagram](/files/d263aa05873ea72918af38788d89fb008f7ecc8f)

*Figure 8: Module-initiated wake sequence with host interface disabled diagram*

1. The MM6108 wakes from sleep and realizes it needs to pass traffic or an event to the host. It begins by asserting the busy pin.
2. The busy pin will fire an interrupt on the host, after which the host will immediately:
3. Raise the Wake PIN.
4. Wait a static period, 10ms
5. Initializes / enables the shared host interface.
6. After asserting the busy pin, the MM6108 will initiate host interface communication immediately. It does not wait until the host ‘enables’ the shared host interface. This is okay, as the bus transaction will be waiting for the host, and an interrupt should fire as soon as the host enables bus interrupts.
7. The busy pin will drop immediately once the MM6108 no longer needs to converse with the host. The host will wait a static period, b, before dropping the wake pin.
8. After the wake pin has fallen, the MM6108 will wait for a period, c, before initiating hardware sleep.

***

#### 3.6.3 MM6108-MF08651 initiates communication with host interface enabled

![Figure 9: Module-initiated wake sequence with host interface enabled diagram](/files/7c295c23e33f8f10f508b966881d0000ea753d61)

*Figure 9: Module-initiated wake sequence with host interface enabled diagram*

1. The MM6108 was previously woken by the host for communication.
2. Sometime after wake and host->MM6108 communication, the MM6108 realizes it needs to send data back to the host (MM6108->host). It will assert the busy pin.
3. The busy pin will fire an interrupt on the host, after which it will immediately:
4. Process the interrupt but take no further action, as the wake pin has already been asserted and the shared host interface is currently enabled/initialized.
5. After MM6108->host communication completion, hardware sleep will be initiated as described above.
