# IQS550BLQNR (Component) ## Description The IQS550 is a projected capacitive touch and proximity trackpad/touchscreen controller implementation on the IQS5XX platform. The IQS550 features best in class sensitivity, signal-to-noise ratio and automatic tuning of electrodes. Low power proximity detection allows extreme low power operation. The IQS550-BL contains a bootloader to enable loading of the B000 firmware. IQS550-A000 devices can be upgraded to the IQS550-B000 firmware via the bootloader. The IQS550-B000 is a firmware upgrade from the IQS550-A000. ## Component Details - **Owner:** giulioz - **Created:** 2/17/2023 - **Last Updated:** 2/17/2023 - **Visibility:** Public - **Datasheet URL:** https://www.azoteq.com/images/stories/pdf/iqs5xx-b000_trackpad_datasheet.pdf - **Manufacturer Part Number:** IQS550BLQNR - **Manufacturer Name:** Azoteq - **Used in:** 28 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
