RLT8762D DLPS模块介绍

DLPS：Deep Low Power State （深度低功耗状态）

RTL8762D supports three modes:

• Power down mode
• Active mode
• Deep Low Power State mode

0.1 DLPS features & restrictions

the detail as following list ：

• System power consumption is 4uA@3V
• System recovers from DLPS within 2ms, and enters DLPS within 1.5ms （进入和退出DLPS需要时间）
• System can be woken up from DLPS by PAD signals （可以通过PAD 信号唤醒DLPS）
• System can be woken up from DLPS by BLE broadcast and connection event periodically. （可以通过BLE广播和BLE连接事件周期性唤醒DLPS）
• As power-off of CPU will cause disconnection of SWD, DLPS mode must be disabled during online debugging with Keil.（使用Keil在线调试时，需要关闭DLPS模式）

0.2 Principle （原理）

?Most of the time, the system is idle and components such as Clock, CPU and Peripherals can be powered off to reduce system power consumption.

When any event is to be handled, the system will be woken up from DLPS mode, Clock, CPU, and Peripherals will be re-powered on and recoverd to

the previous status before entering DLPS, and then the wake-up events will be responded to.

(大部分时间，系统是空闲状态，为了减少系统功耗，需要掉电部件，比如时钟，CPU，外设。当有任何时间需要处理，系统会从DLPS模式唤醒，时钟，CPU，和外设会重新上电，并且会恢复到进入DLPS模式之前的状态，系统会响应唤醒事件)

0.3 Enter/exit DLPS

进入和退出DLPS的条件和流程如上图所示。?
