Description

TS80C52X2 is high performance CMOS ROM, OTP, EPROM and ROMless versions

of the 80C51 CMOS single chip 8-bit microcontroller.

The TS80C52X2 retains all features of the 80C51 with extended ROM/EPROM

capacity (8 Kbytes), 256 bytes of internal RAM, a 6-source, 4-level interrupt system,

an on-chip oscilator and three timer/counters.

In addition, the TS80C52X2 has a dual data pointer, a more versatile serial channel

that facilitates multiprocessor communication (EUART) and an X2 speed improve-

ment mechanism.

The fully static design of the TS80C52X2 allows to reduce system power consumption

by bringing the clock frequency down to any value, even DC, without loss of data.

The TS80C52X2 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.
