IZ7008
8-BIT MICROCONTROLLER WITH LCD DRIVER
IZ7008 is one-chip 8-bit microcontroller made by CMOS technology. The
microcontroller is multi-purpose and can be used in electronic watch, data acquisition
systems, control systems. Low consumption power and full static CMOS logic allow to use
MC in independent systems with limited energy consumption.
Technical characteristics of IZ7008:
ALU bit capacity
RAM size
ROM size
RISC commands system
Stack depth
Interrupter
Maximum number of the controlled
LCD segments
– 8 bits
– 40 bytes
– 1,5 К of commands (16–bit instructions)
– 30 types of commands
– 7 levels
– from 8- inputs and three timers

frequency forming in timer T2).
The counters are for reading only. When reading count register the problems related to the
possibility of reading changeable data may occur. For the correct reading, if necessary, reading of
the data can be done several times in succession with the following comparing of the results.
When the code equal to the contents of registers KT2, KT3 (or at ripple-through carry when
recording 0x00 into registers KT2, KT3), timers T2, T3 are cleared (except mode of notes
frequency forming in timer 2) and "short" pulses FrT2, FrT3 setting respectively interrupt request
flag FR2 into 1 (bit 5 of the state register R7) and Interrupt request flag FR3 in the states register
R7 (bit 6 of the state register R7) are formed.
Flag FR2 is not set into mode of notes frequency forming in timer T2 and in mode when
"short" pulse FrT2 of timer T2 clearing is input signal of timer T3.
The timers are controlled by timers control register RFBO (address 0x7D8)

Timer Т2 can be used in the mode of notes frequency forming for tunes synthesis. The
mode is selected when recording code «10» into 5,4 bits of RFBO control register (IN1-T2=1, IN0-
T2 = 0 ) and timer count enabling.

In this mode setting of interrupt request flag FR2 in the state register R7 is inhibited. Signal of
65565 Hz is applied on counter input.. Notes frequency is formed on counter output (output
T2_7) and can be applied on external output "AL" at the set into 1 flag AL_EN in the state
register R7.
