What is a Counter IC?
A counter IC is an IC that counts externally input clock pulses.
Data counted by an ABLIC counter IC can be accessed using the I2C-BUS interface.
The I2C-BUS interface shrinks the size of the counter IC package, which helps simplify peripheral circuits.
The Strength of ABLIC’s Products
●Use of expertise in analog quartz IC and real-time clock development
ABLIC has gained expertise in designing high-reliability ICs through long experience in developing analog quartz ICs and real-time clocks. This expertise has been used as a component technology in the design of ABLIC’s counter ICs.
| A representative component technology |
Description |
|---|---|
| Power-on detection circuit | When a counter IC is turned on, this circuit initializes an internal register to ensure accurate operation after powering up. |
| Schmitt trigger circuit | This circuit correctly recognizes when the clock rises and falls to enable a correct clock count. |
| Noise suppression circuit | This circuit suppresses noise with a 50 nsec pulse width or less to prevent communication errors in the I2C interface and enables accurate reading of count data. |
●Hardware-enabled IC ensures accurate counting
Unlike software-controlled counters integrated into a microcontroller (MCU), ABLIC’s hardware-enabled counter IC does not hang-up or freeze.
●ABLIC has shipped a total of 175 million timer ICs worldwide (Based on our research as of 2022)
With annual shipments of 175 million counter ICs, real-time clocks and analog quartz ICs, ABLIC has gained the trust of its customers.
Counter IC Proposal
●Using the IC as both a timer and a counter
A microcontroller (MCU) timer can be used with an ABLIC counter IC.
The counter or timer function has to be selected on the MCU.
Select the timer function on the MCU and use an ABLIC counter IC to measure the amount of water and rice in a rice
cooker or other device and set the rice cooker timer, or measure the flow rate per hour of water pipes.
●Application examples
*Use automotive quality compliant products for automotive devices.
