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.

Notes:
1 Dynamic consumption current should be measured without load.
2 The parameters are controlled with oscillator crystal with oscillator nominal frequency 32768 Hz
at capacitance values on oscillator input OSCI not more than 6pF, on output OSCO - not more
than 3pF.
3 Nominal value of integrated capacitances on outputs OSCI and OSCO - 12pF and 12pF(crystal
load capacity CL=6 pF).
