8-bit controller with flash memory of programs
the microcircuit iz7012 – 8-bit controller with the flash – memory of programs (rom testing
coding with the watch functions, stopwatch with the possibility of the intermediate values fixation
and writing of thirty results into memory).
the microcircuit is intended for receipt, processing and indication of data on the liquid crystal
indicator the microcircuit is applicable in the electronic household appliance devices (counters,
electronic watches, electronic thermometers, pedometers).
