TS80C51U2  
TS83C51U2  
TS87C51U2  
Double UART 8-bit CMOS Microcontroller  
1. Description  
TS80C51U2 is high performance CMOS ROM, OTP The fully static design of the TS80C51U2 allows to  
and EPROM versions of the 80C51 CMOS single chip reduce system power consumption by bringing the clock  
8-bit microcontroller.  
frequency down to any value, even DC, without loss of  
data.  
The TS80C51U2 retains all features of the 80C51 with  
extended ROM/EPROM capacity (16 Kbytes), 256 bytes The TS80C51U2 has 2 software-selectable modes of  
reduced activity for further reduction in power  
consumption. In the idle mode the CPU is frozen while  
the timers, the serial port and the interrupt system are still  
operating. In the power-down mode the RAM is saved  
and all other functions are inoperative.  
of internal RAM, a 7-source , 4-level interrupt system,  
an on-chip oscilator and three timer/counters.  
In addition, the TS80C51U2 has a second UART,  
enhanced functions on both UART, enhanced timer 2,  
a hardware watchdog timer, a dual data pointer, a baud  
rate generator and a X2 speed improvement mechanism.
