W86C450

Features of the W86C450 are:(1)easily interface to most popular microprocessors;(2)adds or deletes standard asynchronous communication bit (start,stop,and parity) to or from serial data stream;(3)holding and shitt registers eliminate the need for precise synchronization between the CPU and the serial data;(4)independently controlled transmit,receive,line status,and data set interrupts;(5)programmable baud generator allow division of any input clock by 1 to (2^16-1) and generates the internal 16 * clock;(6)independent receiver clock input;(7)mode control functions (CTS,RTS,DSR,DTR,RI,and DCD);(8)fully programmable serial-interface characteristics;(9)false start bit detection;(10)internal diagostic capabilities;(11)line break generation and detection;(12)fully prioritized interrupt system controls.

The absolute maximum ratings of the W86C450 can be summarized as:(1):the parameter is supply voltage,the symbol is VDD to VSS,the rating is -0.3 to 7.0,the unit is V;(2):the parameter is input voltage,the symbol is VI,the rating is -0.3 to 7,the unit is V;(3):the parameter is operating temperature,the symbol is TOPR,the rating is 0 to +70,the unit is ;(4):the parameter is storage temperature,the symbol is TTG,the rating is -65 to +150,the unit is ;(5):the parameter is power dissipation,the symbol is PD,the rating is 400,the unit is mW.
