Electrical Specifications

5. CPU and Memory Subsystems

5.1 Processor

The ATWINC15x0-MR210xB modules have a Cortus APS3 32-bit processor. This processor performs

many of the MAC functions, including but not limited to the association, authentication, power

management, security key management, and MSDU aggregation/de-aggregation. In addition, the

processor provides flexibility for various modes of operation, such as STA and AP modes.

5.2 Memory Subsystem

The APS3 core uses a 128KB instruction/boot ROM along with a 160KB instruction RAM and a 64KB

data RAM. The ATWINC15x0-MR210xB modules come populated with either 4Mb or 8Mb of Flash

memory depending on the module model that is ordered. This memory can be used for system software.

See Table 1-1 for more information. In addition, the device uses a 128KB shared RAM, accessible by the

processor and MAC, which allows the APS3 core to perform various data management tasks on the TX

and RX data packets.

5.3 Non-volatile Memory (eFuse)

The ATWINC15x0-MR210xB modules have 768 bits of non-volatile eFuse memory that can be read by

the CPU after device reset. This non-volatile one-time-programmable (OTP) memory can be used to store

customer-specific parameters, such as MAC address; various calibration information, such as TX power,

crystal frequency offset, etc.; and other software-specific configuration parameters. The eFuse is

partitioned into six 128-bit banks. Each bank has the same bitmap (see following figure). The purpose of

the first 80 bits in each bank is fixed, and the remaining 48 bits are general-purpose software dependent

bits, or reserved for future use. Since each bank can be programmed independently, this allows for

several updates of the device parameters following the initial programming; for example, if the MAC

address has to be changed, Bank 1 has to be programmed with the new MAC address along with the

values of TX gain correction and frequency offset if they are used and programmed in Bank 0. The

contents of Bank 0 have to be invalidated in this case by programming the invalid bit in the Bank 0. This

will allow the firmware to use the MAC address. By default, all the ATWINC15x0-MR210xB modules are

programmed with the MAC address and the frequency offset bits of Bank 0.

6. WLAN Subsystem

The WLAN subsystem is composed of the Media Access Controller (MAC) and the Physical Layer (PHY).

The following two subsections describe the MAC and PHY in detail.

6.1 MAC

6.1.1 Description

The ATWINC15x0-MR210xB MAC is designed to operate at low power while providing high data

throughput. The IEEE 802.11 MAC functions are implemented with a combination of dedicated datapath

engines, hardwired control logic, and a low-power, high-efficiency microprocessor. The combination of

dedicated logic with a programmable processor provides optimal power efficiency and real-time response

while providing the flexibility to accommodate evolving standards and future feature enhancements.

Dedicated datapath engines are used to implement datapath functions with heavy computational

requirements. For example, an FCS engine checks the CRC of the transmitting and receiving packets,

and a cipher engine performs all the required encryption and decryption operations for the WEP, WPA-

TKIP, and WPA2 CCMP-AES.

Control functions which have real-time requirements are implemented using hardwired control logic

modules. These logic modules offer real-time response while maintaining configurability via the

processor. Examples of hardwired control logic modules are the channel access control module

(implements EDCA/HCCA, Beacon TX control, interframe spacing, etc.), protocol timer module

(responsible for the Network Access Vector, back-off timing, timing synchronization function, and slot

management), MPDU handling module, aggregation/de-aggregation module, block ACK controller

(implements the protocol requirements for burst block communication), and TX/RX control FSMs

(coordinate data movement between PHY-MAC interface, cipher engine, and the DMA interface to the

TX/RX FIFOs).

The MAC functions implemented solely in software on the microprocessor have the following

characteristics:

• Functions with high memory requirements or complex data structures. Examples are association

table management and power save queuing.

• Functions with low computational load or without critical real-time requirements. Examples are

authentication and association.

• Functions which need flexibility and upgradeability. Examples are beacon frame processing and

QoS scheduling.

6.1.2 Features

The ATWINC15x0-MR210xB IEEE802.11 MAC supports the following functions:

• IEEE 802.11b/g/n

communication specified by IEEE 802.11 b/g/n in single stream mode with 20MHz bandwidth. Advanced

algorithms have been employed to achieve maximum throughput in a real world communication

environment with impairments and interference. The PHY implements all the required functions that

include FFT, filtering, FEC (Viterbi decoder), frequency, timing acquisition and tracking, channel

estimation and equalization, carrier sensing, clear channel assessment, and automatic gain control.

7.3 UART Interface

The ATWINC15x0-MR210xB supports the Universal Asynchronous Receiver/Transmitter (UART)

interface. This interface should be used for debug purposes only. The UART is available on pins 14 and

19. The UART is compatible with the RS-232 standard, and the ATWINC15x0-MR210xB operates as

Data Terminal Equipment (DTE). It has a two-pin RXD/TXD interface.

The default configuration for accessing the UART interface of ATWINC15x0-MR210xB is mentioned

below:

• Baud rate: 115200

• Data: 8 bit

• Parity: None

• Stop bit: 1 bit

• Flow control: None

It also has RX and TX FIFOs, which ensure reliable high-speed reception and low software overhead

transmission. FIFO size is 4 x 8 for both RX and TX direction. The UART also has status registers

showing the number of received characters available in the FIFO and various error conditions, as well the

ability to generate interrupts based on these status bits.

An example of the UART receiving or transmitting a single packet is shown in the following figure. This

example shows 7-bit data (0x45), odd parity, and two stop bits.

8. Power Consumption

8.1 Description of Device States

The ATWINC15x0-MR210xB has several device states:

• ON_Transmit – Device is actively transmitting an 802.11 signal. Highest output power and nominal

current consumption.

• ON_Receive – Device is actively receiving an 802.11 signal. Lowest sensitivity and nominal current

consumption.

• ON_Doze – Device is ON but is neither transmitting nor receiving

• Power_Down – Device core supply off (Leakage)

• IDLE connect – Device is connected with 1 DTIM beacon interval

The following pins are used to switch between the ON and Power_Down states:

• CHIP_EN – Device pin (pin #22) used to enable DC/DC Converter

• VDDIO – I/O supply voltage from external supply

In the ON states, VDDIO is on and CHIP_EN is high (at VDDIO voltage level). To switch between

the ON states and Power_Down state CHIP_EN has to change between high and low (GND)

voltage. When VDDIO is off and CHIP_EN is low, the chip is powered off with no leakage (also see

Restrictions for Power States).

8.3 Restrictions for Power States

When no power is supplied to the device, for example, the DC/DC Converter output and VDDIO are both

off (at ground potential), a voltage cannot be applied to the device pins because each pin contains an

ESD diode from the pin to supply. This diode will turn on when a voltage higher than one diode drop is

supplied to the pin.

If a voltage must be applied to the signal pads while the chip is in a low-power state, the VDDIO supply

must be on, so the SLEEP or Power_Down state must be used.

Similarly, to prevent the pin-to-ground diode from turning on, do not apply a voltage that is more than one

diode drop below ground to any pin.

8.4 Power-up/down Sequence

The power-up/down sequence for ATWINC15x0-MR210xB is shown in the Following Figure. The timing

9. Notes On Interfacing to the ATWINC15x0-MR210xB

9.1 Programmable Pull Up Resistors

The ATWINC15x0-MR210xB provides programmable pull up resistors on various pins. The purpose of

these resistors is to keep any unused input pins from floating, which can cause excess current to flow

through the input buffer from the VDDIO supply. Any unused module pin on the ATWINC15x0-MR210xB

should leave these pull up resistors enabled so the pin will not float. The default state at power-up is for

the pull up resistor to be enabled. However, any pin that is used should have the pull up resistor disabled.

The reason for this is that if any pins are driven to a low level while the ATWINC15x0-MR210xB is in the

low power sleep state, current will flow from the VDDIO supply through the pull up resistors, increasing

the current consumption of the module. Since the value of the pull up resistor is approximately 100KΩ,

the current through any pull up resistor that is being driven low will be VDDIO/100K. For VDDIO = 3.3V,

the current through each pull up resistor that is driven low would be approximately 3.3V/100K = 33µA.

Pins which are used and have had the programmable pull up resistor disabled should always be actively

driven to either a high or low level and not be allowed to float.

12. Design Considerations

This section provides the guidelines on placement and routing to achieve the best performance.

12.1 ATWINC15x0-MR210PB Placement and Routing Guidelines

• The module must be placed on the main board – the printed antenna area must overlap with the

carrier board. The portion of the module containing the antenna should not go outside the edge of

the main board. The antenna is designed to work properly when it is sitting directly on top of a

1.5mm thick printed circuit board.

• If the module is placed at the edge of the main board, a minimum 22mm by 5mm area directly

under the antenna must be clear of all metal on all layers of the board. “In-land” placement is

acceptable; however deepness of keep-out area must grove to: module edge to main board edge

plus 5mm. DO NOT PLACE THE MODULE IN THE MIDDLE OF THE MAIN BOARD OR FAR

AWAY FROM THE MAIN BOARD EDGE.

• Keep away from the antenna, as far as possible, large metal objects to avoid electromagnetic field

blocking

• Do not enclose the antenna within a metal shield

• Keep any components which may radiate noise or signals within the 2.4GHz-2.5GHz frequency

band as far away from the antenna as possible, or better yet, shield those components. Any noise

radiated from the main board in this frequency band will degrade the sensitivity of the module.

12.3 ATWINC15x0-MR210UB Placement and Routing Guidelines

The ATWINC15x0-MR210UB module has an Ultra Small Miniature RF Connector (u.FL) for the external

antenna.

The choice of antenna is limited to the antenna types for which the module was tested and approved. For

a list of tested and approved antennas that may be used with the module, refer to the respective country

in 14. Regulatory Approval.

An approved and tested antenna type is shown in the following table.

12.3.1 Recommended External Antenna for ATWINC15x0-MR210UB

Whip Antenna (Part number: RN-SMA-4) along with a 10cm length RF cable assembly (u.FL to SMA) has

been used for the certification of ATWINC15x0-MR210UB. It is recommended to use the same or similar

external antenna in design.

12.4 Module Assembly Considerations

The ATWINC15x0-MR210xB modules are assembled with an EMI Shield to ensure compliance with EMI

emission and immunity rules. The EMI shield is made of a tin-plated steel (SPTE) and is not hermetically

sealed. Solutions like IPA and similar solvents can be used to clean the ATWINC15x0-MR210xB module.

However, cleaning solutions that contain acid should never be used on the module.

The ATWINC15x0-MR210xB modules are not intended for use with a conformal coating and the customer

assumes all risks if a conformal coating is applied to the modules.

13. Reflow Profile Information

This chapter provides guidelines for reflow processes in getting the Microchip module soldered to the

customer’s design. For more information on reflow process guidelines, refer to Solder Reflow

Recommendation Application Note (DS00233D).

13.1 Storage Condition

13.1.1 Moisture Barrier Bag Before Opening

A moisture barrier bag must be stored in a temperature of less than 30°C with humidity under 85% RH.

The calculated shelf life for the dry-packed product shall be 12 months from the date the bag is sealed.

13.1.2 Moisture Barrier Bag Open

Humidity indicator cards must be blue, <30%.

13.2 Printing Process

The printing process requires no significant changes compared to Sn/Pb solder. Any guidelines

recommended by the paste manufacturers to accommodate paste specific characteristics should be

followed. Post-print inspection and paste volume measurement is very critical to ensure good print quality

and uniform paste.

13.3 Baking Conditions

This module is rated at MSL level 3. After a sealed bag is opened, no baking is required within 168 hours

so long as the devices are held at ≤30°C/60% RH or stored at <10% RH.

The module will require baking before mounting if:

• The sealed bag has been open for >168 hours

• Humidity Indicator Card reads >10%

• SIPs need to be baked for 8 hours at 125°C

13.4 Soldering and Reflow Condition

The optimization of the reflow process is the most critical factor to be considered for lead-free soldering.

The development of an optimal profile should take into account the paste characteristics, the size of the

board, the density of the components, the mix of the larger and smaller components, and the peak

temperature requirements of the components. An optimized reflow process is the key to ensuring a

successful lead-free assembly and achieves high yield and long term solder joint reliability.

Temperature Profiling

Temperature profiling should be performed for all new board designs by attaching thermocouples at the

solder joints, on the top surface of the larger components, and at multiple locations of the boards. This is

to ensure that all components are heated to a temperature above the minimum reflow temperatures and

the smaller components do not exceed maximum temperature limit. The SnAgCu solder alloy melts at

~217°C, so the reflow temperature peak at joint level should be 15 to 20°C higher than melting

ATWINC15x0

Reflow Profile Information

temperature. The targeted solder joint temperature for the Sn-Ag-Cu solder should be ~235°C. For larger

or sophisticated boards with a large mix of components, it is also important to ensure that the

temperature difference across the board is less than 10 degrees to minimize board warpage. The

maximum temperature at the component body should not exceed the MSL3 qualification specification.

13.4.1 Reflow Oven

The following items should also be observed in the reflow process:

1. Allowable reflow soldering iterations:

– Three times based on the following reflow soldering profile (refer following Figure).

2. Temperature profile:

– Reflow soldering shall be done according to the following temperature profile (refer to the

following figure).

– Peak temperature: 250°C.

Cleaning

The exposed ground paddle helps to self-align the module, avoiding pad misalignment. The use of no

clean solder pastes is recommended. Full drying of no-clean paste fluxes as a result of the reflow process

must be ensured. This may require longer reflow profiles and/or peak temperatures toward the high end

of the process window as recommended by the solder paste vendor. It is believed that uncured flux

residues could lead to corrosion and/or shorting in accelerated testing and possibly the field.

Rework

Rework is to remove the mounted SIP package and replace with a new unit. It is recommended that once

an ATWINC15x0-MR210xB Module has been removed it should never be reused. During the rework

process, the mounted module and PCB are heated partially, and the module is removed. It is

ATWINC15x0

recommended to pay attention to heat-proof the proximity of the mounted parts and junctions and use the

best nozzle for rework that is suited to the module size.

The ATWINC1500-MR210PB, ATWINC1510-MR210PB, ATWINC1500-MR210UB, and ATWINC1510-

MR210UB modules have received Federal Communications Commission (FCC) CFR47

Telecommunications, Part 15 Subpart C “Intentional Radiators” single-modular approval in accordance

with Part 15.212 Modular Transmitter approval. Single-modular transmitter approval is defined as a

complete RF transmission sub-assembly, designed to be incorporated into another device, that must

demonstrate compliance with FCC rules and policies independent of any host. A transmitter with a

modular grant can be installed in different end-use products (referred to as a host, host product, or host

device) by the grantee or other equipment manufacturer, then the host product may not require additional

testing or equipment authorization for the transmitter function provided by that specific module or limited

module device.

The user must comply with all of the instructions provided by the Grantee, which indicate installation

and/or operating conditions necessary for compliance.

A host product itself is required to comply with all other applicable FCC equipment authorization

regulations, requirements, and equipment functions that are not associated with the transmitter module

portion. For example, compliance must be demonstrated: to regulations for other transmitter components

within a host product; to requirements for unintentional radiators (Part 15 Subpart B), such as digital

devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the

non-transmitter functions on the transmitter module (i.e., Suppliers Declaration of Conformity (SDoC) or

certification) as appropriate (e.g., Bluetooth and Wi-Fi transmitter modules may also contain digital logic

functions).

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the

market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of

these methods, to our knowledge, require using the Microchip products in a manner outside the

operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is

engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

ATWINC15x0

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their

code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”
