Abstract

The invention discloses a wireless remote control encoder chip and application circuit thereof. The wireless remote control encoder chip is internally integrated with a reset unit, a recombined key unit, an oscillating unit, a latch unit, a frequency demultiplication unit, an encoding unit, a unit code generation unit, a recombination unit, an SO drive unit and a PC (Personal Computer) driver unit. The wireless remote control encoder chip has functions of moving forward, moving backward, turning left, turning right and acceleration, and also can implement a demonstration function, so, functions of IC (Integrated Circuit) are enhanced. Meanwhile, recombined key design is used in the wireless remote control encoder chip, and IC port resource is saved. Additionally, the oscillating unit is integrated in the chip, so that the IC port resource is saved, and interference on the IC caused by outside signals is reduced.

Description

technical field [0001] The invention relates to the technical field of chip design, in particular to a wireless remote control coding chip and an application circuit thereof. Background technique [0002] With the development of electronic industry technology, wireless remote control products are more and more widely used in people's daily life. The existing wireless remote control signal processing forms are also various, and the application fields are very wide. Among them, the relatively large use is In remote control toys, home appliance remote control and other fields. At present, the five-function wireless remote control signal coding ASIC used for toys has the functions of forward, backward, left turn, right turn, and acceleration. The application circuit is simple and the cost is low. [0003] Because the wireless remote control coding chip of the existing remote control toys has many pins and the application circuit requires many peripheral devices, this will lead ...
