Frequently Asked Questions - ATWILC1000 Microchip
What is the ATWILC1000?
The ATWILC1000 is a single-chip Wi-Fi module from Microchip that supports IEEE 802.11 b/g/n standards. It integrates a MAC, baseband, RF, and power amplifier in a compact QFN package.
What voltage does the ATWILC1000 require?
The module operates from a 3.0V to 3.6V supply voltage. It is recommended to use a stable 3.3V power source.
Which host interfaces does the ATWILC1000 support?
It supports SPI, SDIO, and I2C interfaces for communication with a host microcontroller. SPI is the most common for low pin count designs.
Is the ATWILC1000 compatible with Arduino?
Yes, Arduino boards can interface with the ATWILC1000 via SPI using libraries like the Microchip WiFi library. Additional level shifting may be needed for 5V boards.
How do I connect an antenna to the ATWILC1000?
The module provides an RF pin for an external antenna, or a PCB trace antenna can be used. A matching network (inductor and capacitor) is required as per the datasheet.
What is the maximum data rate of the ATWILC1000?
The maximum data rate is 72.2 Mbps when using HT20 (20 MHz channel) with 802.11n. With 802.11g, the rate is up to 54 Mbps.
Does the ATWILC1000 support Bluetooth?
No, the ATWILC1000 is a Wi-Fi-only solution. It does not include Bluetooth functionality. For combined Wi-Fi/Bluetooth, consider the ATWILC1000B or similar.
What is the power consumption of the ATWILC1000?
Typical power consumption is about 300 mA during transmission and 10 μA in sleep mode. Actual values depend on output power and data rate settings.
How can I update the firmware on the ATWILC1000?
Firmware updates can be performed via SPI or SDIO using Microchip's firmware update tool. The module has a dedicated bootloader that supports OTA updates.
Where can I find the datasheet and application notes?
The official datasheet, application notes, and design resources are available on the Microchip website under the product page for ATWILC1000. Search for ATWILC1000 in the documentation section.
