P5346003 is a communication single-chip microcomputer integrated circuit and it is widely used in caller id telephone.
First,Functions FeatureS346003 integrated circuit internal basically contains the following functions: FSK circuit frequency shift keying decoder (the decoder is according with BlLL202 and ITU-TV23 standard). LCD drive and control circuit can directly drive LCD screen.A frequency signal generator DTMF, which can achieve a frequency dial-up and the audio signal output controlled by software.The battery is low voltage detection circuit: software control energy saving mode control circuit.
Second,Pins Functions and DataP5346003 integrated circuits uses 30 feet encapsulation, and it is directly sealed in the printed circuit board.It is a kind of four microcomputer and the integrated circuit pins functions are shown as table 1.
