MK3200GLF

Overview

The MK3200GLF is a low-power clock oscillator manufactured by Renesas Electronics Corporation, formerly IDT. It generates a precise 32.768 kHz output from an external 32.768 kHz crystal resonator. The device utilizes advanced sub-micron CMOS technology to achieve minimal power consumption of 3.5 µA in normal operation while operating within a voltage range of 2.5 V to 5 V. Packaged in an 8-pin MSOP (3.00 mm body) or SOIC format, it includes a power-down pin and an Output Enable pin for tri-stating the output during in-circuit testing.

Feature Summary

• Generates 32.768 kHz CMOS output from standard crystal input
• Low power consumption of 3.5 µA in normal operation
• Includes Power Down and Output Enable pins for control and testing
• Available in lead-free 8-pin MSOP or SOIC packages

Applications

• Real-time clock circuits in embedded systems
• Battery-powered portable devices requiring low standby current
• In-circuit testing environments utilizing output tri-state capability

Procurement Notes

Verify the specific package variant (MSOP vs. SOIC) and suffix codes against official Renesas documentation, as distributor listings may vary. Confirm RoHS compliance status and check for end-of-life notices, as legacy IDT components may have limited availability or obsolescence risks. Ensure the supplier provides valid traceability for industrial temperature grades if required.

Selection Notes

Select the MK3200GLF when a fixed 32.768 kHz reference is sufficient for timing applications. Compare with the MK3200G series for identical electrical specifications but different packaging or lead-free status. Consider alternative oscillators only if MHz frequency synthesis or differential outputs are required, as this part is designed specifically for low-frequency crystal-driven generation.

Part Context

The MK3200GLF belongs to the MK32xx family of clock generators originally developed by Integrated Device Technology (IDT), which was acquired by Renesas Electronics. This component serves as a cost-effective solution for replacing discrete VCXOs or standard oscillators in designs requiring a stable 32.768 kHz source derived directly from a crystal resonator.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Cross-reference with MK3200G or MK3200SITR variants for package differences. Verify functional compatibility with any generic 32.768 kHz CMOS oscillators if pin-out and voltage levels match.
