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.
