8-BIT CONTROLLER WITH MASK PROGRAMMING
Microcircuit IZ7013 – 8-bit controller with the mask programming (ROM test coding with the
functions of the electronic wrist watch with the five program alarm, stopwatch and timer).
The microcircuit is intended for receipt, processing and indication of data on the liquid crystal indi-
cator The microcircuit is applicable in the electronic household appliance devices (counters,
electronic watches, electronic thermometers, pedometers).
Main Features:
• ROM capacity, QROM, bits………………………………2560х16;
• RAM capacity, QRAM, bits…………………..…………..72х8;
• Number of bits of ALU, bits………………………..……8;
• Sources of interruptions………………………….…….from 8 inputs,
from event counter at input IN8,
from three timers;
• Maximum number of controlled……………………….136 (34 LCD control drivers
LCD segments………………………………….…........at multiplex levels 1/2,1/3,1/4);
• RISC-system of instructions………………………….…30 types of instructions;
• Stack…………………………………………………….…7 levels;
• Accepted value of potential
of static electricity, V
………………..…....1500
(for pins IN1-IN4, OSCI, OSCO)…………………..….(1000)
• Operating temperature range …………………………- 40 … +85 °С.

Status register R4
The mask «programming» may switch off the output level (Z instead of L or (and) Z instead of H)
with their possible replacement with the external resistors.
H – high level status ( 1 );
L – low level status ( 0 );
Z – high impedance status.

Program flag
1 – switching on the driver of the electroluminescent backlight
(outputs IND, EL).
0 – switching off the driver of the electroluminescent backlight
(pins IND, EL)
0 – sound denial (microcircuit pins AL=0, NAL=1).
1 – sound permission (microcircuit pins AL=1, NAL=0), if R4_0=0 or
timer bitt Т_2=0
1 – with sound permission, i. e. at R4_1=1, pins AL=1, NAL=0, if
the timer bit Т_2=0, otherwise the microcircuit pins AL=0, NAL=1,
if the timer bit Т_2=1.
0 – with sound permission, i. e. at R4_1=1,
pins AL = 1, NAL = 0 independently on the timer bit Т_2
