Power Dissipation 1 W(2)DescriptionTS80C54/58X2 is high performance CMOS ROM, OTPand EPROM versions of the 80C51 CMOS single chip8-bit microcontroller.
The TS80C54/58X2 retains all features of the AtmelWireless & Microcontrollers 80C51 with extendedROM/EPROM capacity (16/32 Kbytes), 256 bytes ofinternal RAM, a 6-source , 4-level interrupt system, anon-chip oscilator and three timer/counters.
In addition, the TS80C54/58X2 has a HardwareWatchdog Timer, a more versatile serial channel thatfacilitates multiprocessor communication (EUART) anda X2 speed improvement mechanism.
The fully static design of the TS80C54/58X2 allows toreduce system power consumption by bringing the clockfrequency down to any value, even DC, without loss ofdata.
The TS80C54/58X2 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.
