P87C511

The P87C511 is a single-chip control-oriented microcontroller which is fabricated on intel's reliable CHMOS III-E technology.The power down mode saves the RAM contents but freezes the oscillator,causing all other chip functions to be inoperative.

The electrical characteristics of the P87C511 can be summarized as:(1):the parameter is operating temperature under bias,the rating is -40 to +85,the unit is ;(2):the parameter is storage temperature range,the rating is -65 to +150,the unit is ;(3):the parameter is voltage on EA/VPP pin to VSS,the rating is 0 to +13.0,the unit is V;(4):the parameter is voltage on any other pin to VSS,the rating is -0.5 to +6.5,the unit is V;(5):the parameter is maximum IOL per I/O pin,the rating is 15,the unit is mA;(6):the parameter is power dissipation (based on package heat transfer limitations,not device power consumption),the rating is 1.5,the unit is W.

The operating conditions of the P87C511 can be summarized as:(1):the symbol is TA,the parameter is ambient temperature under bias commerical,the rating is 0 to +70,the unit is ;(2):the symbol is TA,the parameter is ambient temperature under bias express,the rating is -40 to +85,the unit is ;(3):the symbol is VCC,the parameter is supply voltage,the rating is 4.5 to 5.5,the unit is V;(4):the symbol is fOSC,the parameter is oscillator frequency,the rating is 3.5 to 16,the unit is MHz.
