180M-51LFT

Overview

The Renesas 180M-51LFT is a spread spectrum clock generator IC manufactured by Renesas Electronics Corporation. It operates with a single circuit and provides a 1:1 input-to-output ratio, utilizing CMOS outputs without differential signaling capabilities. The device supports a maximum frequency of 28MHz and functions within a supply voltage range of 3.135V to 5.5V. Designed for surface mount assembly, it is housed in an 8-SOIC package (0.154 inch width). The component includes an internal PLL and accepts crystal or external clock inputs. It is rated for an operating temperature range of 0°C to 70°C and complies with RoHS3 standards.

Feature Summary

• Spread Spectrum Clock Generator with integrated PLL for EMI reduction
• CMOS output interface with 1:1 input-to-output ratio
• Operates on 3.135V to 5.5V supply voltage
• Maximum frequency capability of 28MHz

Applications

• General-purpose clock generation in embedded systems
• Low EMI applications requiring spread spectrum modulation
• Industrial control circuits operating within commercial temperature ranges

Procurement Notes

The 180M-51LFT is classified as obsolete with a confirmed End-of-Life notification dated March 24, 2022. Verification of the specific ordering suffix 'LFT' indicates a Tape & Reel packaging format. Prospective users must confirm current availability through authorized channels, as standard production has ceased. Cross-reference with the base product number 180M is required for legacy support documentation.

Selection Notes

Selection requires verifying compatibility with the target system's power supply constraints between 3.135V and 5.5V. The device lacks programmable features according to available data; therefore, fixed frequency specifications must match design requirements. The 8-SOIC package dimensions and thermal characteristics should be validated against PCB layout constraints. Ensure the application environment remains within the specified 0°C to 70°C operating temperature range.

Part Context

This component belongs to the 180M family of clock generators from Renesas Electronics. It shares the base architecture with variants such as the 180M-51LF, differing primarily in packaging configuration. The part is distinct from the 180MI series, which denotes different performance characteristics. Documentation references often cite the ICS180-51 datasheet for technical parameters.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status, direct pin-compatible replacements require independent verification against updated Renesas portfolios or third-party equivalents.
