IZ7010
CIRCUIT FOR ELECTRON PEDOMETER - ERGOMETER
DESCRIPTION
The chip is a silicon-gate CMOS LSIs for electron pedometer-ergometer with
function watch and alarm. Its provides count and indication of steps, calories, kilometers
during current day and night and summing up at changing 24 hours, steps , calories,
kilometers with values stored previous ( mode «TOTAL DATA »). Length of steps setting
from 25 to 95 centimeters. Frequency of registered pulses from external sensor at
counting steps is no more than 6Hz at duration of time between the end of previous and
beginning of counted pulse no less than 100 ms. Counting steps to 999999.
