The DS1844 is an Econo Oscillator with Nonvolatile Control, manufactured by Dallas Semiconductor (now Maxim Integrated). It provides a digitally controlled oscillator with a nonvolatile memory to store the oscillator's settings. This allows for precise frequency adjustment and retention of the settings even after power loss.

Applications:

• Clock Generation
• Frequency Synthesis
• Timing Control
• Microprocessor Clocking
• Embedded Systems

Features:

• Digitally Controlled Oscillator
• Nonvolatile Memory for Frequency Setting
• I2C Interface for Control and Programming
• Wide Frequency Range
• Low Power Consumption
• Small Package Size

Benefits:

• Provides precise frequency control
• Eliminates the need for external potentiometers or trim capacitors
• Simplifies interfacing with microcontrollers
• Offers flexibility in frequency selection
• Minimizes system power requirements
• Allows for compact system design

The DS1844 offers a convenient solution for generating and controlling frequencies in various electronic systems. The nonvolatile memory ensures that the oscillator's settings are retained even after power loss. The I2C interface simplifies programming and control. Although it is an end-of-life product, it may still be available through some distributors.
