8-bit CMOS Microcontroller 0-60 MHz
TS80C52X2
1. Description
TEMIC 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 TEMIC
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 a X2 speed
improvement 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.
