ICM7216B Key Features
- Functions as a frequency counter (DC to 10MHz)
- Four internal gate times: 0.01s, 0.1s, 1s, 10s in frequency counter mode
- Directly drives digits and segments of large multiplexed LED displays (mon anode and mon cathode versions)
- Single nominal 5V supply required
- Highly stable oscillator, uses 1MHz or 10MHz crystal
- Internally generated decimal points, interdigit blanking, leading zero blanking and overflow indication
- Display off mode turns off display and puts chip into low power mode
- Hold and reset inputs for additional flexibility
- Functions also as a period counter, unit counter, frequency ratio counter or time interval counter
- 1 cycle, 10 cycles, 100 cycles, 1000 cycles in period, frequency ratio and time interval modes
ICM7216B Applications
- Functions as a frequency counter (DC to 10MHz)
- Four internal gate times: 0.01s, 0.1s, 1s, 10s in frequency counter mode
