Embodiment Construction

[0020] Referring to Figure 1, this embodiment includes an oscillator and timing generation circuit, a controller, address coding and data output control logic, data detection, synchronization detection, decoding logic, model control logic, and various functions of buttons and anti-shake circuits unit.

[0021] As shown in Figure 1, the address and data are 12 bits in total. According to different uses, the chip can be configured into different circuit models. When used as a 6-way switch control, the data is 6 bits, and the address is 6 bits; when used as 4 When controlled by a road switch, the data is 4 bits, the address is 8 bits, and so on. The data output is a transient trigger flip type, whether it is a remote control button or a manual button, press the switch once to turn it on, and press it again to turn it off. Remote control data enters the chip from the DIN pin.

[0022] Here we define, 1-bit data, 11-bit address is model 1; 2-bit data, 10-bit address is model 2; a...

Abstract

The remote control switch decode chip of electric appliance comprises an oscillator, a time schedule generating circuit, a control circuit for address coding and data output, a detection unit, a decoding logical unit, a type control logical circuit, and a key-press and jitter-prevention circuit. This invention improves system stability with low cost.

Description

Technical field: [0001] The invention relates to a remote control switch decoding chip, more specifically a remote control switch decoding chip capable of multi-type configuration. Background technique: [0002] For a long time, household lighting has been manually switched instead of controlled by remote controllers like TVs and air conditioners, which brings inconvenience to people in use. For example, if a person watching TV in bed wants to turn off the light, he has to get up and get out of bed. [0003] According to the different household lighting configurations, the decoding chips of the remote control switches need to have different types of configurations. So far, there is no remote control switching decoding chip that can be configured with multiple types. Invention content: [0004] In order to avoid the disadvantages of the above-mentioned prior art, the present invention provides a remote control switch decoding chip for electrical appliances that has two con...
