P8044AH

The P8044AH integrates a high performance 8-bit microcontroller,the intel 8051 core,with a intelligent/high performance HDLC/SDLC serial communication controller,called the serial interface unit(SIU).

Features of the P8044AH are:(1)optimized for real time control 12 MHz clock,priority interrupts,32 programmable I/O lines,two 16-bit timer/counters;(2)boolean processor;(3)4K*8 ROM,192*8 RAM;(4)64K accessible external proggram memory;(5)64K accessible external data memory;(6)4s multiply and divide;(7)serial communication processor that operates concurrently to CPU;(8)2.4 Mbps maximum data rate;(9)375 Kbps using on-chip phase locked loop;(10)communication software in silicon;(11)operates as an SDLC primary or secondary station.

The absolute maximum ratings of the P8044AH can be summarized as:(1):the parameter is ambient temperature under bias,the value is 0 to +70,the unit is ;(2):the parameter is storage temperature,the value is -65 to -150,the unit is ;(3):the parameter is voltage on EA,VPP pin to VSS,the value is -0.5 to -21.5,the unit is V;(4):the parameter is voltage on any other pin VSS,the value is -0.5 to -7,the unit is V;(5):the parameter is power dissipation,the value is 2,the unit is W.
