IZ7007 Circuit for electron pedometer - ergmeter Short characteristics Functions performed: - 5 functions for counting time and calendar with indication of hours, minutes, seconds, month, date , count the quantity of steps by means of evaluation and counting pulses from external sensor ; count and indication of steps, calories, kilometers , miles during current day and night (mode «DAILY STEPS COUNTER»); summing up at changing 24 hours, steps , calories, kilometers , miles with values stored previous ( mode «TOTAL STEPS COUNTER»). Features: - - imbed in chip element of quartz generator with operating frequency of 32768 Hz, capacity, resistor, and voltage doubler; 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 , kilometres and miles according to the following ratios: (10 steps = 0.24 calorie = 0.0073 klm = 0.0045 mile ; 1000 steps = 24 calorie = 0.73 klm = 0.456 mile ); indication of distance in miles and kilometers starting from 0.001, calories, starting from 0.1. Operating temperatures range operating temperatures range from -0 to +70°С. 1 IZ7007 Тable 1 - Limiting and extreme modes Symbol in letters UCC1 UCC2 UIH UIL Name of parameter, mode , unit of measurement Primary supply voltage from the source of voltage, V Secondary supply voltage, V Input voltage of high level, V Input voltage of low level, V min Extreme mode max 1,2 1,8 2UCC1-0,3 UCC1-0,3 Uss Limiting mode min max -0,3 2,0 2UCC1 UCC1 Uss+0,3 -0,3 -0,3 -0,3 4,0 UCC1+0,3 UCC1+0,3 Таble 2 - Electric parameters (Таmb = 25°С ) Name of the parameter in letters Standard min max mode of unit of measurement measurement Consumption current in primary supply voltage chain from voltage source ICC1 - 0.6 UCC1=1.8 V µА Consumption current in secondary supply voltage chain ICC2 - 1.2 UCC1=1.8 V µА dynamic consumption current ICCO - 3.0 without load UCC1=1.65 V µА IIL - 5 UCC1=1.65 V UIL=0.3 V µА - 8 UCC1=1.8 V UIL=0.3 V Input current of low level on inputs S, M, D, COUNT Voltage of quartz generator start UOSC - 1.45 t≤5 с V voltage of quartz generator break-down UOSP - 1.2 - V ST CALLS AM PМ F E A G KM MILIS COL B C D 1 2 P3 3 4 P4 5 P5 TOTAL TODAY Figure1 - Format LCD Таble 3 – LCD segments State 2 6 P6 IZ7007 Segment COM1 COM2 Segment COM1 COM2 SEG28 SEG27 SEG26 SEG25 SEG24 SEG23 SEG22 SEG21 SEG20 SEG19 SEG18 SEG17 SEG16 SEG15 AM BC1 ST A2 B2 COL F3 CALLS B3 C3 P3 F4 A4 B4 PM E2 F2 G2 C2 D2 E3 A3 G3 D3 TODAY E4 G4 C4 SEG14 SEG13 SEG12 SEG11 SEG10 SEG9 SEG8 SEG7 SEG6 SEG5 SEG4 SEG3 SEG2 SEG1 P4 KM A5 B5 C5 F6 A6 B6 C6 P6 MILIS A7 B7 C7 D4 E5 F5 G5 D5 P5 E6 G6 D6 TOTAL E7 F7 G7 D7 LCD COM2 SEGMENTS COM1 GND.
