98ULPA877AHLFT

Application Specific Clock/Timing Overview

The Renesas Electronics 98ULPA877AHLFT is a low-power, 1.8V DDR-II PLL clock driver belonging to the 98ULPA877A series. Designed for high-speed memory interfaces, this component integrates a Phase-Locked Loop (PLL) to generate precise clock signals required for DDR-II SDRAM applications. The device operates at a supply voltage of 1.8V and is housed in a VFQFPN-40 surface-mount package. It is classified under Clock Drivers & Distribution within the Clock & Timer ICs subcategory. The product is currently marked as End-of-Life (EOL) by the manufacturer.

Application Specific Clock/Timing Feature Summary

• Integrated PLL for DDR-II clock generation
• Low power operation at 1.8V supply voltage
• VFQFPN-40 surface mount package

Application Specific Clock/Timing Applications

• DDR-II SDRAM interface timing
• High-speed memory controller systems

Application Specific Clock/Timing Procurement Notes

This component is officially designated as End-of-Life (EOL) by Renesas Electronics. Availability is restricted or non-existent through standard distribution channels. Verification of current stock status with authorized distributors is required before procurement planning. Alternative solutions should be considered due to the discontinued status.

Application Specific Clock/Timing Selection Notes

Select this part only if legacy DDR-II designs specifically require the 98ULPA877A series characteristics. Ensure the design supports the 1.8V operating voltage and VFQFPN-40 footprint. Given the EOL status, verify that the specific suffix 'HLFT' matches the required tape-and-reel packaging configuration for existing production lines.

Application Specific Clock/Timing Part Context

The 98ULPA877AHLFT is part of the broader 98ULPA877A family of clock drivers. Variants within this family, such as the 98ULPA877AKLFT, share similar core functionalities but may differ in packaging or minor electrical specifications. This specific model targets DDR-II applications, distinguishing it from other series members designed for different memory standards or interface types.

Application Specific Clock/Timing Replacement Considerations

As an End-of-Life product, direct substitutes are not guaranteed. Review Renesas documentation for recommended replacement parts or newer generations of clock drivers compatible with DDR-II interfaces. Cross-reference pinouts and electrical parameters carefully when evaluating potential alternatives.
