MK3200SLF

Overview

The MK3200SLF is a low-power clock oscillator manufactured by Renesas Electronics Corporation, originally developed by Integrated Device Technology (IDT). It generates a precise 32.768 kHz output signal from an external crystal input. The device is housed in an 8-SOIC package with dimensions of 4.90 x 3.90 mm and a height of 1.38 mm. It operates within a supply voltage range of 2.5 V to 5 V and supports CMOS output levels. Designed for efficiency, it consumes only 3.5 µA in normal operation and includes a power-down mode. The component is RoHS compliant and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Generates 32.768 kHz clock signal from inexpensive crystal input
• Ultra-low power consumption of 3.5 µA in normal operation
• Includes power-down mode and Output Enable pin for tri-stating
• Available in lead-free 8-SOIC or 8-MSOP packages

Applications

• Real-time clock circuits in embedded systems
• Low-power consumer electronics requiring precise timing
• Industrial control systems operating in wide temperature ranges

Procurement Notes

Verify the manufacturer source, as this part was originally an IDT product now distributed by Renesas. Confirm the specific suffix 'LF' indicates lead-free compliance and check for any obsolete notices or last-time-buy statuses associated with the SH family transition. Ensure the 8-SOIC package matches the design footprint requirements.

Selection Notes

Select the MK3200SLF when a cost-effective, low-power 32.768 kHz oscillator is required for battery-operated devices. Compare against the MK3200SI variant if tape-and-reel packaging is preferred over tubes. Verify that the 2.5V to 5V supply range aligns with the system's power rails and that the CMOS output voltage levels are compatible with the receiving logic.

Part Context

The MK3200 series belongs to IDT's (now Renesas) portfolio of standard clock oscillators designed to replace discrete VCXOs and crystals. It is part of a broader family including variants like the MK3200SITR and MK3200SI, which share core functionality but differ in packaging or shipping formats. This component serves as a foundational timing source for microcontrollers and real-time clocks.

Replacement Considerations

Direct substitutes include MK3200SI and MK3200SITR from IDT/Renesas. Cross-manufacturer alternatives should be verified for pin compatibility and electrical specifications.
