General Description, **Section 1**
AMW037 `•` AMW037 Datasheet
## **1 General Description**
The AMW037 module from Zentri provides an advanced stand-alone Wi-Fi and networking solution.
An integrated module avoids difficult RF layout and enables designers to rapidly embed Wi-Fi and secure networking functionality into virtually any device.
The ZentriOS embedded connected operating system, pre-programmed into all modules, may be used to fasttrack module integration into end-products.
With dimensions of just 16.5mm x 23.5mm and a wide temperature range, the module is suitable for integration into most embedded applications.
The Wi-Fi device includes an integrated RF transmit power amplifier and provides superior Wi-Fi performance and full compatibility with all 2.4GHz 802.11b/g/n Wi-Fi networks.
The module is powered by a single 3.3V power supply.
Various powersave modes offer ultra-low power operation. Wake from low power sleep mode is possible using IO pins or the internal real-time clock, and wake from ultra-low power standby mode is achieved using the dedicated wake pin.
The module has numerous modular approvals. See Section 7, Regulatory Certification.
## **1.1 ZentriOS**
This document is designed to cover the physical and electrical characteristics of the AMW037 module. For information on ZentriOS see:

## **2 Block Diagram**
Figure 1 is a block diagram of the AMW037 module. The main components of the module are a Wi-Fi System-onChip (SoC) and the quad-SPI serial flash. The processor and peripherals are driven by a 40MHz crystal. An onboard 2 MByte serial flash chip may be used to store user
applications, data and configuration, and firmware images as part of the Zentri secure over the air (OTA) update process.

Electrical Specifications, **Section 3**
AMW037 Datasheet
## **3.4 Digital IO Characteristics**
All digital IO pads are bidirectional, non-inverting and tri-state. Each pad includes an input and an output buffer with tristate control inputs. When the AMW037 is powered down, all output enable signals can be set to hold high or low to minimize power consumption.
The hold functionality introduces some positive feedback into the pad. Hence, the external driver that drives the pad must be stronger than the positive feedback. The required drive strength is however small – in the range of 5uA.
**Table 6. Digital IO Characteristics**
|**Parameters**|**Min**|**Max**|**Unit**|
|---|---|---|---|
|Input low voltage|-0.3|0.25 x VDD|V|
|Input high voltage|0.75 x VDD|3.6|V|
|Input leakage current||50|µA|
|Output low voltage||0.1 x VDD|V|
|Output high voltage|0.8 x VDD||V|
|Input pin capacitance||2|pF|
|Maximum drive capability||12|mA|

## **6.3 Recommended PCB Footprint**
All dimensions in Figure 5 are in thousands of an inch unless otherwise marked.
**Figure 5. AMW037 Recommended Footprint (Top)**
A = 925mil (23.5mm) B = 685mil (17.4mm) C = 240mil (6.1mm) D = 650mil (16.5mm) E = 30mil (0.76mm) F = 90mil (2.3mm) G = 27.5mil (0.7mm) H = 25mil (0.64mm) I = 50mil (1.27mm) J = 100mil (2.54mm) K = 70mil (1.78mm)
## **6.4 Routing Recommendations**
When designing a carrier board, the addition of ground fill directly underneath the AMW037 module, rather than signal or power traces, is recommended. All ground pads adjacent to antenna pins must be connected to a solid ground plane. Failure to comply with these recommendations may result in degraded performance of WLAN functionality.

## **6.6 Application Examples**
## **Operation using ZentriOS**
Each AMW037 module is pre-installed with and licensed to use ZentriOS-WL, Zentri’s feature-rich and reliable WiFi networking application. The module can be used with an external host microcontroller via the serial interface command API.
To use ZentriOS-WL with a host processor, the module only requires an external connection to power and a UART serial interface. A host processor connects to the UART (pins 10/11) as shown in Figure 8. Zentri recommends UART hardware flow control (RTS/CTS) is used to improve the reliability of data communications. All required pull up/down resistors are included inside the module.
For hardware design guidelines, see:
https://docs.zentri.com/hardware/zentri/amwx06/amwx06-hardware-design#pcb-layout
The general guidelines for the AMWx06 devices apply to all Zentri devices.

The Zentri AMW037 module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Sub-part C “Intentional Radiators” modular approval in accordance with Part 15.212 Modular Transmitter approval. Modular approval allows the end user to integrate the AMW037 module into a finished product without obtaining subsequent and separate FCC approvals for intentional radiation, provided no changes or modifications are made to the module circuitry. Changes or modifications could void the user’s authority to operate the equipment. The end user must comply with all of the instructions provided by the Grantee which indicate installation and/or operating conditions necessary for compliance.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
If the exterior label area is smaller than the palm of the hand, the end product user manual must contain the above statement. The user manual should contain the following additional statement:
The finished product is required to comply with all applicable FCC equipment authorization, regulations, requirements, and equipment functions not associated with the transmitter module portion. For example, compliance must be demonstrated to regulations for other transmit-

## **8 Packaging, Handling and Storage, RoHS**
## **8.1 Packaging**
Modules are shipped in cut tape, with ESD-safe packaging, or in reels.
For package quantity, see section 9, Ordering Information.
Reels are shipped enclosed inside a moisture resistant sealed bag. The shelf life of the sealed reel is 12 months at 40°C and <90% Relative Humidity (RH). Please refer to the bag seal date and the following section for handling & storage.
Ensure that all modules are managed in accordance with Moisture Sensitive Level 3 (MSL3) per **IPC/JEDEC J-STD-20** .
If reflow is required, AMW037 modules must be baked first, according to Joint Industry Standard J-STD-033C.
## **8.2 Handling & Storage**
## **CAUTION**
## **MSL3 Sensitive Device!**
The AMW037 module is a moisture sensitive device rated at Moisture Sensitive Level 3 (MSL3) per **IPC/JEDEC J-STD20** .
After opening the moisture sealed storage bag, modules that will be subjected to reflow solder or other high temperature processes must be:
1. mounted to a circuit board within 168 hours at factory conditions (≤30°C and <60% RH)
**OR**
## 2. 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 reflow.
## **8.3 RoHS Directive**
The AMW037 module is produced according to the RoHS (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment) directive and complies with the directive.

## **9 Ordering Information**
You can order AMW037 modules as either cut tape loaded with an unspecified ZentriOS, or as a full reel of **500** units, pre-loaded with either a specific ZentriOS version or a version of your embedded custom application.
When you order, refer to the OPN (Orderable Part Number), as described below. For examples, see Table 6 - Ordering Information below.
## **9.1 Ordering an Unspecified ZentriOS Version**
## **OPN: AMW037**
When ordering an unspecified ZentriOS version as cut tape, the OPN is simply AMW037.
When the ZentriOS version is unspecified, orders of AMW037 modules ship with whatever versions of ZentriOS are available. The ZentriOS version is not guaranteed to be the same for all items shipped. Cut tape is suitable for sampling, evaluation, and pilot builds.
Upon delivery, you can update modules individually, via OTA (Over-The-Air update), with a specific firmware version.
## **9.2 Ordering a Specific ZentriOS-WL Version or a Custom Firmware Version**
## **ZentriOS version OPN: AMW037-x.y.zR**
