P8052AH

The P8052AH is designed as one member of the MCS 51 controllers which are optimized for control applications. Byte-processing and numerical operations on small data structures are facilitated by a variety of fast addressing modes for accessing the internal RAM. The instruction set P8052AH provides a convenient menu of 8-bit arithmetic instructions, including multiply and divide instructions.

P8052AH has twelve features. (1)High performance HMOS process. (2)Internal timers/event counters. (3)2-level interrupt priority structure. (4)32 I/O lines (four 8-bit ports). (5)64K external program memory space. (6)Security feature protects EPROM parts against software piracy. (7)Boolean processor. (8)Bit-addressable RAM. (9)Programmable full duplex serial channel. (9)111 instructions (64 signal cycle). (10)64K external data memory space. (11)Extended temperature range which would be from -40°C to 85°C. Those are all the main features.

Some absolute maximum ratings of P8052AH have been concluded into several points as follow. (1)Its ambient temperature under bias would be from -40°C to 85°C. (2)Its storage temperature range would be from -65°C to 150°C. (3)Its voltage on EA/Vpp pin to Vss would be from -0.5V to 13V. (4)Its voltage on any other pin to Vss would be form -0.5v to 7V. (5)Its power dissipation would be 1.5W. It should be noted that stressing the device beyond the "absolute maximum ratings" may cause permanent damage.

Also some electrical characteristics of P8052AH are concluded as follow. (1)Its input low voltage would be min -0.5V to 0.8V. (2)Its input high voltage except XTAL2, RST would be min 2.0V and max Vcc+0.5V. (3)Its input high voltage to XTAL2, RST would be min 2.5V and max Vcc+0.5V. (4)Its output low voltage would be max 0.45V. (5)Its output high voltage would be min 2.4V. (6)Its logic 0 input current would be max -500uA. (7)Its pin capacitance would be max 10pF. And so on.
