Why to add up to peaceful to choose HT67L2540A to be used in beautiful aspersion bibcock in plan of initiative cable video?
The beautiful aspersion bibcock of Holtek generates electricity oneself monitor plan made full use of the low power comsumption of HT67L2540A is characteristic, came true to reduce the goal of power comsumption through the following respects:
Clock of system of the MCU when waking up chooses MIRC: When MCU is waked up, systematic clock chooses MIRC (clock of multistage and variable rate) , this kind of means can acquire better balance between power comsumption and traversal speed. MIRC allows MCU to adjust its job frequency according to effective demand, reduce power comsumption thereby, the property that keeps enough at the same time will handle the task.
Dormancy power comsumption is low: The power comsumption that HT67L2540A issues in dormancy mode is very low, be less than 1 μ A@3V. This is meant when should spending aspersion bibcock to be not used, MCU can enter dormancy mode, reduce power comsumption with utmost ground, prolong battery life thereby (if the system uses batteries power supply) .
MCU is built-in the drive of C Type LCD that takes referenced voltage: The LCD driver with built-in HT67L2540A has referenced voltage function, below the case that can show screen open in LCD, the electricity that keeps inferior is used up, be less than 3 μ A@3V. This provided outstanding indication result not only, still ensured low power comsumption of the system moves.
Integrated above is characteristic, plan of initiative cable video can satisfy the beautiful aspersion bibcock of Holtek well each requirement of low power comsumption, fall in scene of initiative electric field especially, character of these low power comsumption move to ensuring systematic abidance is stable crucial. Through optimizing the design of power comsumption of the clock choice of MCU, dormancy and LCD driver, this plan asperses faucet for the flower initiative cable video offerred solution of efficient, credible low power comsumption.
