The IQS550-B000 is a firmware upgrade from the IQS550-A000. 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.
