Description
TS80C31X2 is high performance CMOS and ROMless versions of the 80C51 CMOS
single chip 8-bit microcontroller.
The TS80C31X2 retains all features of the TSC80C31 with 128 bytes of internal RAM,
a 5-source, 4 priority level interrupt system, an on-chip oscilator and two
timer/counters.
In addition, the TS80C31X2 has a dual data pointer, a more versatile serial channel
that facilitates multiprocessor communication (EUART) and a X2 speed improvement
mechanism.
The fully static design of the TS80C31X2 allows to reduce system power consumption
by bringing the clock frequency down to any value, even DC, without loss of data.
The TS80C31X2 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.
