180MI-01LF

Overview

The Renesas 180MI-01LF is a spread spectrum clock generator IC designed for low electromagnetic interference (EMI) applications. It operates within a supply voltage range of 3.135V to 5.5V and supports a maximum output frequency of 28MHz. The device utilizes a Phase-Locked Loop (PLL) architecture with a 1:1 input-to-output ratio, accepting clock or crystal inputs and providing CMOS outputs. Packaged in an 8-SOIC surface-mount format, it functions reliably across a commercial temperature range of 0°C to 70°C. This component is classified as a dedicated spread spectrum clock generator intended for timing signal generation.

• Maximum operating frequency of 28MHz
• Supply voltage range of 3.135V to 5.5V
• 8-SOIC surface mount package

Applications

• Low EMI clock generation systems
• General purpose clock distribution
• Timing circuits requiring spread spectrum modulation

Procurement Notes

The 180MI-01LF is officially listed as End-of-Life (EOL) by the manufacturer. Discontinuance notifications have been issued, indicating that production has ceased. Availability is limited to existing stock, which may be exhausted without further replenishment. Verification of current supplier inventory and final availability is required before procurement planning.

Selection Notes

Designers should consider the fixed 1:1 frequency ratio and the 28MHz maximum frequency limit when selecting this component. The device requires a 3.135V to 5.5V power supply and operates within a 0°C to 70°C temperature range. Due to its discontinued status, alternative components with similar spread spectrum capabilities and compatible pinouts must be evaluated for new designs.

Part Context

This part belongs to the 180M series of clock generators from Renesas Electronics. It is functionally related to variants such as the 180M-01LF and 7152MI-01LF, sharing the SOIC-8 package form factor. The 180MI-01LF specifically targets applications requiring spread spectrum modulation to minimize radiated emissions in digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Given the End-of-Life status, engineers must identify cross-reference components independently based on electrical specifications and pin compatibility.
