Technical Product Brief
The 88MW300/302 application subsystem is powered by
an ARM Cortex-M4F CPU that operates up to 200 MHz.
The device supports an integrated 512 KB SRAM,
128 KB mask ROM, and a QSPI interface to external
Flash. An integrated Flash Controller with a 32 KB
SRAM cache enables eXecute In Place (XIP) support for
firmware from Flash.

A complete set of digital and analog interfaces enable
direct interfacing for I/O avoiding the need for external
chips. The application CPU can be used to support
custom application development avoiding the need for
another microcontroller or processor.
Figure 1 shows an overall block diagram of the device.

The SoC provides a full array of peripheral interfaces
including SSP/SPI/I2S (3x), UART (3x), I2C (2x), General
Purpose Timers and PWM, ADC, DAC, Analog
Comparator, and GPIOs. It also includes a hardware
cryptographic engine, RTC, and Watchdog Timer. The
88MW302 includes a high speed USB On-The-Go
(OTG) interface to enable USB audio, video, and other
applications.

The SoC includes a full-featured W LAN subsystem
powered by proven and mature IEEE 802.11n/g/b
Marvell technology. The WLAN subsystem integrates a
WLAN MAC, baseband, and direct-conversion RF radio
with integrated PA, LNA, and transmit/receive switch. It
also integrates a CPU subsystem with integrated
memory to run Marvell WLAN firmware to handle real
time WLAN protocol processing to off-load many WLAN
functions from the main application CPU.
Li
A high degree of integration enables very low system
costs requiring only a single 3.3V power input, a
38.4 MHz crystal, and SPI Flash. The RF path needs
only a lowpass filter for antenna connection.
The SoC is designed for low-power operation and
includes several low-power states and fast wake-up
times. Multiple power domains and clocks can be
individually shut down to save power. The SoC also has
a high-efficiency internal PA that can be operated in
low-power mode to save power. The microcontroller and
WLAN subsystems can be placed into low-power states,
independently, supporting a variety of application use
cases. An internal DC-DC regulator provides the 1.8V
rail for the WLAN subsystem.
rk
The Marvell® 88MW300/302 is a highly integrated,
low-power WLAN Microcontroller System-on-Chip (SoC)
solution designed for a broad array of smart devices for
Internet of Things (IoT), wearables, accessories,
Machine-to-Machine (M2M), home automation, and
Smart Energy applications.

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.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and,
if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular cannot be installed in any
portable device, for example, USB dongle like transmitters is forbidden.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This
transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This modular
must be installed and operated with a minimum distance of 20 cm between the radiator and user body.
If the FCC identification number is not visible when the module is installed inside another device, then the outside
of the device into which the module is installed must also display a label referring to the enclosed module. This
exterior label can use wording such as the following: “Contains Transmitter Module FCC ID:
2AFC3WIFI300SMT01 or Contains FCC ID: 2AFC3WIFI300SMT01”
when the module is installed inside another device, the user manual of this device must contain below warning
statements;
1. 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.
(2) This device must accept any interference received, including interference that may cause undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the
user documentation that comes with the product
