UPD71051L

The UPD71051L-10 is one of the UPD71051 series.It is a CMOS USART designed to provide serial data communications in microcomputer systems.The CPU uses it as a peripheral I/O device and programs it to communicate in synchronous or asynchronous serial data transmission protocols,including IBM bisync.

Features of the UPD71051L-10 are:(1)synchronous operation one or two SYNC characters internal/external synchronization automatic SYNC character insertion;(2)asynchronous operation clock rate:(baud rate)*1,*16,or *64 send stop bits:1,1.5,or 2bits break transmission automatic break detection valid start bit detection;(3)baud rate:DC-240 kbit/s at*1 clock;(4)full duplex,double-buffered transmitter/receiver;(5)error detection:parity,overrun,and framing;(6)five-to eight-bit characters;(7)low-power standby microcomputers;(8)functionally equivalent to (except standby mode)and can replace the UPD8251AF;(9)CMOS technology;(10)single +5V±10% power supply;(11)industrial temperature range:-40 to +85;(12)28-pin plastic DIP or PLCC or 44-pin plastic QFP;(13)8MHz and 10MHz.

The absolute maximum ratings of the UPD71051L-10 can be summarized as:(1)power supply voltage,VDD:-0.5V to +7.0V;(2)input voltage,VI:-0.5V to VDD+0.3V;(3)output voltage,VO:-0.5V to VDD+0.3V;(4)operating temperature,Topt:-40 to +85;(5)storage temperature,Tstg:-65 to +150;(6)power dissipation,PDmax:1.0W.
