S333025T-32.768K-R

Oscillators Overview

The S333025T-32.768K-R is a standard crystal oscillator manufactured by Aker Technology Corp, designed for precise timing applications requiring a 32.768 kHz output frequency. It utilizes HCMOS output logic and operates on a single 3.3V supply voltage. The device features an enable/disable function for power management control. Frequency stability is rated at ±25ppm over the operating temperature range. The component is housed in a compact 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm x 1.20mm maximum height. It supports surface-mount installation and functions within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Integrated enable/disable functionality for active power management
• HCMOS output signal compatibility for digital logic interfaces
• Compact surface-mount package design optimized for space-constrained PCB layouts

Oscillators Applications

• Real-time clock circuits in portable electronic devices
• Low-power microcontroller system timing references
• Embedded systems requiring precise low-frequency synchronization

Oscillators Procurement Notes

Verify that the specific part number matches the required enable/disable feature and HCMOS output type. Confirm the supply voltage requirement aligns with the 3.3V specification. Ensure the physical footprint corresponds to the 4-SMD, No Lead package dimensions of 3.20mm x 2.50mm. Check that the operating temperature range meets the application's environmental requirements of -40°C to +85°C. Validate frequency stability needs against the ±25ppm rating before procurement.

Oscillators Selection Notes

Select this component when a low-frequency 32.768 kHz reference is needed with integrated power control. The HCMOS output suits direct interfacing with digital logic without additional buffering. The small form factor benefits high-density board designs. Consider the ±25ppm stability sufficient for general real-time clock applications rather than high-precision metrology. Ensure the 3.3V supply voltage is available in the target circuit design.

Oscillators Part Context

This oscillator belongs to Aker Technology Corp's line of surface-mount crystal oscillators. It provides a stable clock source for timing-critical applications. The 32.768 kHz frequency is standard for dividing down to one-second intervals in timekeeping circuits. The enable pin allows system-level power optimization during idle states.

Oscillators Replacement Considerations

Compatible substitutes include other 32.768 kHz HCMOS oscillators with similar 3.3V operation and enable features. Verify package dimensions match the 3.20mm x 2.50mm footprint. Ensure frequency stability and temperature range specifications meet or exceed the original requirements.
