TS87C52X2

TS80C52X2

8-bit Microcontroller 8 Kbytes ROM/OTP, ROMless

1. Description

TS80C52X2 is high performance CMOS ROM, OTP, 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.

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.

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.

In addition, the TS80C52X2 has a dual data pointer, a

more versatile serial channel that facilitates

multiprocessor communication (EUART) and a X2 speed

improvement mechanism.
