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
calendar with indication of hours,
minutes, seconds, month, date ;
Alarm clock;
Count the quantity of steps by means
of evaluation and counting pulses
from external sensor ;
count and indication of steps, calories,
kilometers during current day and
night (mode « DATA OF THE
CURRENT DAY”);
Conversion of made steps into
calories with consideration of the user
coefficient with consideration of
height, weight and male/female
identification;
summation up at changing 24 hours,
steps , calories, kilometers with
values stored previous ( mode
«TOTAL DATA»).
