General Description
M88WI6800-K is a single-chip Wi-Fi micro controller
with SPI Flash / UART interface. The chip fully
complies with IEEE 802.11b/g/n 1T1R 2.4 GHz
standards.
M88WI6800-K integrates a 32-bit micro processor, a
802.11n MAC, a baseband processor and a 2.4 GHz
RF transceiver including power amplifier, low noise
amplifier and RF T/R switch into a single die. Robust
RF calibration algorithms, such as IQ-imbalance
correction, Tx LO leakage removal and Rx DC offset
cancellation, are built-in to alleviate the radio front-end
impairments in RF/Analog circuits. The baseband
processor, designed with adaptive channel estimation,
enhanced boundary detector and soft-decision Viterbi
decoder, is capable of providing mitigation even in
severe multi-path environments. The 32-bit processor
core with over 200MIPS and over 100 kByte
programmable memory is embedded with TCP/IP
protocol stack. In addition, the chip comes with 32 kHz
low-speed clock timers, 2 12-bit ADCs with voltage
range of 0 V - 3.3 V, 4 channel hardware PWM drivers
with tunable frequency range and maximum 18 GPIOs
with interrupt control. It contains also a power
management unit and a high-efficiency DC-DC
converter for cost effective system implementation.
M88WI6800-K is available in 6x6mm QFN48 package.
It is an ideal solution for network enabled applications,
such as Internet of Things, with few external circuit
components and minimized PCB size. The networking
system built with the chip can operate in Station mode,
Soft-AP mode or AP/Station mode.

Federal Communications Commission (FCC) Statement
15.21
You are cautioned that changes or modifications not expressly approved by the part
responsible for compliance could void the user’s authority to operate the equipment.
15.105(b)
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.
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 of the device.
FCC RF Radiation Exposure Statement:
1. This Transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
2. This equipment complies with RF radiation exposure limits set forth for an uncontrolled
environment.
FCC RF Radiation Exposure Statement:
1. This Transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
2. For body worn operation, this device has been tested and meets FCC RF exposure
guidelines. When used with an accessory that contains metal may not ensure compliance
with FCC RF exposure guidelines.
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna
may be installed such that 20 centimeter may be maintained between the antenna
and users. The final end product must be labeled in visible area with the following:
“Contains FCC ID: 2AEDFWM6800K”
Manual Information to the End user
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the end
product which integrates this module.
The end user manual shall include all required regulatory information/warning as
show in this manual.
