Host Controller Power Management
Power is automatically managed by the firmware based on input device activity. As a power-saving task, the firmware controls the
disabling of the on-chip regulator when in deep sleep (HIDOFF) mode.
BBC Power Management
There are several low-power operations for the BBC:
n Physical layer packet handling turns RF on and off dynamically within packet TX and RX.
n Bluetooth-specified low-power connection mode. While in these low-power connection modes, the CYBT-X430XX-01 runs on the
Low Power Oscillator and wakes up after a predefined time period.
The CYBT-X430XX-01 automatically adjusts its power dissipation based on user activity. The following power modes are supported:
n Active mode
n Idle mode
n Sleep mode
n HIDOFF (Deep Sleep) mode
The CYBT-X430XX-01 transitions to the next lower state after a programmable period of user inactivity. Busy mode is immediately
entered when user activity resumes.
In HIDOFF (Deep Sleep) mode, the CYBT-X430XX-01 baseband and core are powered off by disabling power to LDOOUT. The VDDO
domain remains powered up and will turn the remainder of the chip on when it detects user events. This mode minimizes chip power
consumption and is intended for long periods of inactivity.
