Power Dissipation 1 W(2)DescriptionTS87C52X2 is high performance CMOS ROM, OTP,EPROM and ROMless versions of the 80C51 CMOSsingle chip 8-bit microcontroller.
The TS87C52X2 retains all features of the 80C51 withextended ROM/EPROM capacity (8 Kbytes), 256 bytesof internal RAM, a 6-source , 4-level interrupt system,an on-chip oscilator and three timer/counters.
In addition, the TS87C52X2 has a dual data pointer, amore versatile serial channel that facilitatesmultiprocessor communication (EUART) and a X2 speedimprovement mechanism.
The fully static design of the TS87C52X2 allows toreduce system power consumption by bringing the clockfrequency down to any value, even DC, without loss ofdata.
The TS87C52X2 has 2 software-selectable modes ofreduced activity for further reduction in powerconsumption. In the idle mode the CPU is frozen whilethe timers, the serial port and the interrupt system are stilloperating. In the power-down mode the RAM is savedand all other functions are inoperative.
