General Description

ADS-MWx36-102R • AMWx36 Datasheet Page |1

1 General Description

The AMW036 and AMW136 modules from Zentri

combine a microcontroller with a CYW43362 Wi-Fi

device to provide an advanced stand-alone Wi-Fi and

networking solution.

The term AMWx36 refers to either module.

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 serial-to-Wi-Fi application, pre-

programmed into all modules, may be used to fast-

track module integration into end-products.

With dimensions of just 20.3mm x 22.9mm and a wide

temperature range, the module is suitable for

integration into most embedded applications.

The Wi-Fi device from Cypress Semiconductor

Corporation 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. A single PCB antenna is provided to simplify

the RF design requirements.

The microprocessor is based on a high-performance

ARM® 32-bit Cortex™-M4.

The AMW036/AMW136 microcontroller core operates

at a frequency up to 84/100MHz providing up to 125

DMIPS or 1.25 DMIPS/MHz (Dhrystone 2.1).

The AMW036 has 96KB of RAM.

The AMW136 has 128KB of RAM.

The AMWx36 module offers extensive I/O and

peripheral interfaces listed below, and provides

additional interface combinations by leveraging

multiplexing and alternate function capabilities.

 2 x 4-Wire UART interfaces

 2 x SPI interfaces (1 master, 1 slave)

 21 x GPIOs

 9 x 12-bit A/D converters

 14 x PWM outputs

 1 x ultra-low power wake input

The module is powered by a 3.3V power supply, a

separate WLAN power supply pin is provided to

minimize noise coupling into the WLAN subsystem.

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 incorporates a 32.768kHz crystal to

maintain an accurate real time clock. A 32kHz clock

output is available on a dedicated module pin in both

active power save modes. The 32kHz clock output may

be used to drive the clock input of other system devices.

This avoids the need for an additional crystal thereby

minimizing total system cost.

The module has numerous modular approvals. See

Section 7, Regulatory Certification.

Block Diagram

ADS-MWx36-102R • AMWx36 Datasheet Page |2

2 Block Diagram

Figure 1 is a block diagram of the AMWx36 module. The

main components of the module are a microprocessor

and CYW43362 Wi-Fi System-on-Chip (SoC). The

processor and peripherals are driven by a 26MHz

crystal. The integrated real-time clock (RTC) is driven by

a 32.768kHz crystal. An on-board 1MByte serial flash

chip may be used to store user data and configuration,

additional applications, and firmware images as part of

the Zentri secure over the air (OTA) update process.

The WLAN subsystem is controlled by ZentriOS enabling

the module to achieve minimum power consumption

when the Wi-Fi networking interface is not required. A

single PCB antenna is provided to simplify the RF design

requirements.

Notes:

1. I = Input, O = Output, S = Supply

2. Factory reset is sampled at power-on-reset and available for other purposes thereafter.

3. The module Reset pin is connected to the internal MCU via a 1k resistor.

We recommend driving the pin. If the pin is not driven, connect a 0.1uF capacitor to ground close to the pin to

bypass noise which may cause unintended reset.

6.6 Application Examples

6.6.1 Operation using ZentriOS Serial

Interface

Each AMWx36 module is pre-installed with and

licensed to use ZentriOS, Zentri’s feature-rich and

reliable Wi-Fi networking application. The AMW036

and AMW136 modules can be used with an external

host microcontroller via the serial interface command

API. The AMW136 module can also be used via a Native

API app running on the internal microcontroller.

To use Zentri’s easy-to-use ZentriOS serial-to-Wi-Fi

application, the module only requires an external

connection to power and a UART serial interface. A host

processor connects to UART0 (pins 17-20) as shown in

Figure 8.

7.1 United States

The Zentri AMWx36 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 AMWx36 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.

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 transmitter components within the host product;

to requirements for unintentional radiators (Part 15 Sub-

part B “Unintentional Radiators”), such as digital devices,

computer peripherals, radio receivers, etc.; and to

additional authorization requirements for non-

transmitter functions on the transmitter module (i.e.

Verification, or Declaration of Conformity) (e.g.,

transmitter modules may also contain digital logic

functions) as appropriate.

7.1.1 Labeling and User Information

Requirements

The AMWx36 module has been labelled with a unique

FCC ID number, and if the FCC ID is not visible when the

module is installed inside another device, then the

outside of the finished product into which the module is

installed must also display a label referring to the

enclosed module. This exterior label can use wording as

follows:

Contains FCC ID: 2ABPY-B5BD9

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

7.1.2 RF Exposure

All transmitters regulated by FCC must comply with RF

exposure requirements. OET Bulletin 65, Evaluating

Compliance with FCC Guidelines for Human Exposure to

Radio Frequency Electromagnetic Fields, provides

assistance in determining whether proposed or existing

transmitting facilities, operations or devices comply with

limits for human exposure to Radio Frequency (RF) fields

adopted by the Federal Communications Commission

(FCC). The bulletin offers guidelines and suggestions for

evaluating compliance.

If appropriate, compliance with exposure guidelines for

mobile and unlicensed devices can be accomplished by

the use of warning labels and by providing users with

information concerning minimum separation distances

from transmitting structures and proper installation of

antennas.

The following statement must be included as a CAUTION

statement in manuals and OEM products to alert users

of FCC RF exposure compliance:

If the AMWx36 module is used in a portable application

(i.e., the antenna is less than 20 cm from persons during

operation), the integrator is responsible for performing

Specific Absorption Rate (SAR) testing in accordance

with FCC rules 2.1091.
