Microchip's ATWINC1500 is an IEEE 802.11 b/g/n IoT network controller. It is the ideal add-on to existing MCU solutions bringing Wi-Fi and Network capabilities through SPI-to-Wi-Fi interface. The ATWINC1500 connects to any SAM or PIC MCU with minimal resource requirements. The ATWINC1500's most advanced mode is a single stream 1x1 802.11n mode.

The ATWINC1500 features a fully integrated Power Amplifier, LNA, Switch and Power Management. The WINC1500 provides internal Flash memory as well as multiple peripheral interfaces including UART and SPI. The only external clock source needed for the ATWINC1500 is a high-speed crystal or oscillator (26 MHz). The ATWINC1500 is available in a QFN package or as a certified module.

The ATWINC1500 has 4 Mb of flash memory which can be used for system software. The ATWINC1510 has 8 Mb flash memory for even greater flexibility.

A MCU host driver can be found in the Advanced Software Framework (ASF).
