IQS525
The IQS525 is a projected capacitive touch and proximity trackpad/touchscreen controller implementation on the IQS5XX platform. The IQS525-B000 is a firmware upgrade from the IQS525-A000. The IQS525 features best in class sensitivity, signal-to-noise ratio and automatic tuning of electrodes. Low power proximity detection allows extreme low power operation. The IQS525-BL contains a bootloader to enable loading of the B000 firmware. IQS525-A000 devices can be upgraded to the IQS525-B000 firmware via the bootloader.
