Product Overview

Category

The DS2423P belongs to the category of integrated circuits (ICs).

Use

It is primarily used for data logging and monitoring applications.

Characteristics

• The DS2423P is a 1-Wire® counter with memory.
• It provides two counters that can be used to measure events or keep track of elapsed time.
• The device operates in a wide temperature range, making it suitable for various environments.

Package

The DS2423P is available in a small form factor package, which allows for easy integration into electronic systems.

Essence

The essence of the DS2423P lies in its ability to accurately count events and store the count values in non-volatile memory.

Packaging/Quantity

The DS2423P is typically sold in reels or tubes, with a quantity of 250 units per reel/tube.

Specifications

• Supply Voltage: 2.8V to 5.25V
• Operating Temperature Range: -40°C to +85°C
• Memory Size: 2048 bits
• Counter Resolution: 16 bits
• Data Rate: 15.4kbps

Detailed Pin Configuration

The DS2423P has a total of 6 pins:

1. VCC: Power supply input
2. GND: Ground reference
3. DQ: 1-Wire data line
4. NC: No connection
5. CNT0: Counter 0 input/output
6. CNT1: Counter 1 input/output

Functional Features

• Event Counting: The DS2423P can accurately count events on both counter inputs.
• Elapsed Time Measurement: It can also be used to measure the time elapsed between events.
• Non-Volatile Memory: The count values are stored in non-volatile memory, ensuring data retention even when power is lost.
• 1-Wire Interface: The device communicates using the 1-Wire protocol, allowing for easy integration into existing systems.

Advantages and Disadvantages

Advantages

• Accurate event counting and time measurement
• Non-volatile memory ensures data retention
• Small form factor package for easy integration
• Wide operating temperature range

Disadvantages

• Limited counter resolution (16 bits)
• Requires a 1-Wire interface for communication

Working Principles

The DS2423P works by monitoring the state of the counter inputs and incrementing the count values accordingly. It uses non-volatile memory to store the count values, ensuring that they are retained even when power is lost. The device communicates with the host system using the 1-Wire protocol, enabling simple and efficient data transfer.

Detailed Application Field Plans

The DS2423P finds applications in various fields, including:

1. Energy Monitoring: It can be used to measure energy consumption by counting pulses from utility meters.
2. Industrial Automation: The device can track the number of cycles or events in industrial processes.
3. Environmental Monitoring: It is suitable for monitoring environmental parameters such as rainfall, wind speed, or temperature by counting corresponding events.
4. Security Systems: The DS2423P can be utilized to monitor the number of door openings or detect unauthorized access attempts.

Detailed and Complete Alternative Models

1. DS2423: Similar to the DS2423P, but without the small form factor package.
2. DS2425: Provides additional counters and features for more complex applications.
3. DS2438: Combines event counting with other sensor capabilities, such as temperature and voltage measurement.

These alternative models offer different specifications and functionalities, catering to diverse application requirements.
