We are using CY8CMBR3116-LQXIT for touch keypad interface.
My question about the current consumption of chip.
As you mention that "Average current consumption of 22 μA per sensor at 120-ms refresh interval" in datasheet.
We did three different test to verify it.
1. Do not configure any button or proxy sensor.
2. Configure only one button.
3. Configure Proxy Sensor(CS0/PS0).
4. Proxy + 4 Button
Case 1: Do not configure any button or proxy sensor.
