Description
The ICM7216A and ICM7216B are fully integrated Timer
Counters with LED display drivers. They combine a high
frequency oscillator, a decade timebase counter, an
8-decade data counter and latches, a 7-segment decoder,
digit multiplexers and 8-segment and 8-digit drivers which
directly drive large multiplexed LED displays. The counter
inputs have a maximum frequency of 10MHz in frequency
and unit counter modes and 2MHz in the other modes. Both
inputs are digital inputs. In many applications, amplification
and level shifting will be required to obtain proper digital
signals for these inputs.
The ICM7216A and ICM7216B can function as a frequency
counter, period counter, frequency ratio (f
A
/f
B
) counter, time
interval counter or as a totalizing counter. The counter uses
either a 10MHz or 1MHz quartz crystal timebase. For period
and time interval, the 10MHz timebase gives a 0.1
μ
s
resolution. In period average and time interval average, the
resolution can be in the nanosecond range. In the frequency
mode, the user can select accumulation times of 0.01s, 0.1s,
1s and 10s. With a 10s accumulation time, the frequency
can be displayed to a resolution of 0.1Hz in the least
significant digit. There is 0.2s between measurements in all
ranges.
The ICM7216D functions as a frequency counter only, as
described above.
All versions of the ICM7216 incorporate leading zero
blanking. Frequency is displayed in kHz. In the ICM7216A
and ICM7216B, time is displayed in
μ
s. The display is
multiplexed at 500Hz with a 12.2% duty cycle for each digit.
The ICM7216A is designed for common anode displays with
typical peak segment currents of 25mA. The ICM7216B and
ICM7216D are designed for common cathode displays with
typical peak segment currents of 12mA. In the display off
mode, both digit and segment drivers are turned off,
enabling the display to be used for other functions.
