Power Consumption and Device Operating Modes
The CY8CMBR2016 is designed to meet the low power
requirements of battery powered applications. To design for the
lowest operating current -

■
To know more about the steps to reduce power consumption,
refer to
There are two device operating modes:
■
■
Low Power Sleep Mode
The following flow chart describes the low power sleep mode
operation.
Figure 14. Low Power Sleep Mode Operation
For details on Low power sleep look at the
11
Response Time
Response Time is the minimum amount of time the button should
be touched for the device to detect as valid button touch.
