UPD17234MC

The UPD17234MC is 4-bit singlechip microcontrollers for small general-purpose infrared remote control transmitters.It employs a 17K architecture of general-purpose register type devices for the CPU, and can directly execute operations between memories instead of the conventional method of executing operations through the accumulator.In addition, a one-time PROM model, UPD17234MC, to which data can be written only once, is also available.It is convenient either for evaluating the UPD17234MC subseries programs or small-scale production of application systems.
 
The absolute maximum ratings of the UPD17234MC can be summarized as:(1):the parameter is supply voltage,the symbol is VDD,the rating is -0.3 to +3.8,the unit is V;(2):the parameter is input voltage,the symbol is VI,the rating 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 high-level output current,the symbol is IOH,the REM pin peak value is -36.0,the REM pin rms value is -24.0,the 1 pin (P0E pin) peak value is -7.5,the 1 pin (P0E pin) rms value is -5.0,the total of P0E pins peak value is -22.5,the total of P0E pins rms value is -15.0,the unit is mA;(5):the parameter is low-level output current,the symbol is IOL,the 1 pin (P0B, P0C, P0D,P0E, P1A0, REM pins) peak value is 7.5,the 1 pin (P0B, P0C, P0D,P0E, P1A0, REM pins) rms value is 5.0,the total of P0B, P0C, P0D,P1A0, REM pins peak value is 22.5,the total of P0B, P0C, P0D,P1A0, REM pins rms value is 15.0,the total of P0E pins peak value is 30.0,the total of P0E pins rms value is 20.0,the unit is mA;(6):the parameter is operating temperature,the symbol is TA,the rating is -40 to +85,the unit is ;(7):the parameter is storage temperature,the symbol is Tstg,the rating is -65 to +150,the unit is ;(8):the parameter is power dissipation,the symbol is Pd,the rating is 180,the unit is mW.
