UPD17015

The UPD17015 is a super low-voltage 4-bit single-chip microcontroller for digital tuning applications.It features a prescaler that can operate at frequencies up to 220 MHz, a PLL synthesizer, and an LCD controller/driver,all configured in one chip.Since this microcontroller can operate at low voltages (VDD = 1.8 to 3.6 V), it is ideal for controlling portable, batterypowered units such as portable radios, headphone stereo sets, and radio-cassette players.
 
The absolute maximum ratings of the UPD17015 can be summarized as:(1):the parameter is supply voltage,the symbol is VDD,the rating is -0.3 to +4.0,the unit is V;(2):the parameter is input voltage,the symbol is VI,the CE pin is -0.3 to VDD+0.6,the except for the CE pin is 0.3 to VDD+0.3,the unit is V;(3):the parameter is output voltage,the symbol is VO,the rating is -0.3 to VDD+0.3,the unit is V;(4):the parameter is output high current,the symbol is IOH,the each pin is -3.0,the total of all pins is -20.0,the unit is mA;(5):the parameter is output low current,the symbol is IOL,the each pin is 3.0,the total of all pins is 20.0,the unit is mA;(6):the parameter is operating ambient temperature,the symbol is TA,the rating is -40 to +50,the unit is ;(7);the parameter is storage temperature,the symbol is Tstg,the rating is -55 to +125,the unit is .
