Features:
100% brand new and high quality.
NL6621M is a SOC of high integration, dedicated to wireless LAN products of high data throughput and low cost.
It integrates MCU, MAC, 1T1R baseband and RF transceiver with amplifier onto one chip.
NL6621M supports 802.11b/ g n and Wi-Fi direct (SDIO network card mode), BSS STA, soft AP, WiFi protection setup.
Also it supports WMM-PS and WPA/ WPA2 security protocol.
NL6621M can both serve as slave controlled by main processor and independent WLAN device needing no other processors.
The general purpose interfaces it supported include QuadSPI, standard SPI, I2C, UART, GPIO, I2S audio and PWM audio.
NL6621M can be directly connected to plentiful peripheral equipment such as sound box, pick-up head, flash memory and LCD, etc.
Plentiful internet protocols such as TCP/ IP, UPD and HTTP, etc. have been integrated to nl6621m.
With high-performance transmission over radio, plentiful interfaces and protocols, NL6621M is a best choice for monolithic chip solution such as wireless audio, wireless video, wireless wisdom household and wireless medical treatment, etc.
