IZ7010

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. FEATURES FUNCTIONS  One-chip CMOS constructions  Single 1.5V battery operation  Imbed in chip element of quartz generator with operating frequency of 32768 Hz, capacity, resistor, and voltage doubler  Built-in LCD driver for control of 7-digit LCD in the mode of two level multiplexing with the mode marks “STEPS”, "km", "КCАL", "CОEFF", "L STEP", "ALARM", "TODAY”, "TOTAL", divided by colons and dots.  Operation from one battery with the voltage of 1.5V, low consumption power;  Availability of circuits of contacts bracing suppression on buttons inputs;  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;  Conversion of quantity of steps into calories , kilometers  5 functions for counting time and cal...
