Introducing Our Counter IC

A counter IC is an IC that can count externally input clock pulses.
ABLIC’s counter IC can read the counter data via the I2C-bus interface.
This capability supports the development of a variety of measuring instruments, infrastructure meters, amusement devices, life counters, etc.

  1. The counter data can be read via the I2C-bus interface
  2. Countable from 0 to 16,777,215 (24 bits)
  3. Ultra-low current consumption: 10nA typ.

1.The counter data can be read via the I2C-bus interface

Unlike general-purpose logic binary counter ICs with parallel output, this IC can read the counter data output via the I2C-bus serial interface from a microcontroller or other system.

2.Countable from 0 to 16,777,215 (24 bits)

The counter is configured as a 24-bit binary-up counter and can count from 0 to 16,777,215 (24 bits).
Whenever the counter reaches 16,777,215, the LOOP (counter loop flag output) pin toggles the output (Low –> High –> Low –>…).  This allows the user to confirm the output state of the Loop pin using the microcontroller or other means and use the system to add to the counter value to count beyond 16,777,215.detail of counter IC operation

3.Ultra-low current consumption: 10nA typ.

A current consumption of 10nA is extremely low compared to the current consumption of an event counter in a microcontroller.
Use of this IC instead of the microcontroller event counter will enable counting clock pulses at low current consumption when the microcontroller is in sleep mode and will help to substantially reduce system power consumption.
