CST5165A/5165S1

    CST5165A/5165S1 series are 4-bits micro-controller which could play 4 channel melody or 4 channel ADPCM with PWM direct drive circuit. PWM resolution is 8/10/12 bits. They include a low cost, high performance CMOS micro-processor. The clock frequency of this up is typically 8.192 (±3%) MHz. This chip operates over a wide voltage range of 2.0V~5.5V. It contains program ROM (PROM) and data ROM (DROM) inside. The maximum program ROM is 8K words and maximum data ROM size is 496K byte. The maximum working SRAM is (256+2) nibbles. It is provided with total 16 software programmable I/O Ports.

        -If input only ports are employed, Port E defined as input only ports. 
        -If output only ports are employed, Port C defined as output only ports. 
        -If input/output ports are selected, Port CE defined as input/output ports bit by bit. 
      Four reset condition: 
        -Low voltage reset. (LVR = 2.0V) 
        -Power on reset. 
        -External reset pin. (active low)
