Problems solved by technology

[0003] However, this approach makes it necessary to add an additional DC-DC converter to the overall mechanism of the wireless mouse, resulting in an increase in cost
In addition, although it is powered by a single battery, the overall mechanism is equivalent to working at the 3V operating voltage provided by the DC-DC converter, which is not conducive to effective system power consumption control for the wireless mouse, thus shortening the battery life. service life

Abstract

The invention provides a micro-control processing chip of a built-in voltage converter and a wireless mouse using the same. The micro-control processing chip comprises a DC-DC converter, a timer, a central processing module, an input and output interface and a timing control module. The DC-DC converter converts a first DC voltage of a battery into a second DC voltage, and the timer outputs a timing signal; the central processing module controls the wireless mouse to enter a power saving mode based on the state of the timing signal; in the power saving mode, the input and output interface outputs a wake-up signal according to the state of an operating member, and the central processing module controls the wireless mouse to enter into an operation mode according to the state of the wake-up signal; and the timing control module controls one of the first DC voltage and the second DC voltage according to the states of the timing signal and the wake-up signal to supply operation voltage for the wireless mouse. The micro-control processing chip and the wireless mouse provided by the invention enhance system integration level, reduce the mechanism costs and can effectively manage power.

Description

technical field [0001] The invention relates to a micro-control processing chip, in particular to a micro-control processing chip with a built-in voltage converter and a wireless mouse using the same. Background technique [0002] Currently, most wireless mice are powered by two batteries (that is, providing a voltage of 3V) to provide operating voltages for the micro-control processing chip and other peripheral components in the wireless mouse. For the application requirements of a single battery (that is, providing a voltage of 1.5V), which is gradually becoming mainstream in the market, the usual solution is to couple a DC-DC converter to the output of the single battery to convert the single battery The voltage provided by the battery is boosted to 3V. [0003] However, in this way, an additional DC-DC converter must be added to the overall mechanism of the wireless mouse, resulting in an increase in cost. In addition, although it is powered by a single battery, the ov...
