Application Specific Clock/Timing Procurement Notes

The 932S421BGLFT has been officially discontinued by Renesas Electronics Corporation, with End-of-Life notifications issued in January and February 2022. Verification of current availability should focus on surplus or aftermarket channels rather than direct manufacturer stock. Buyers must confirm the specific revision level and packaging format, such as tape and reel quantities, when sourcing replacement units from third-party distributors.

Application Specific Clock/Timing Selection Notes

Designers requiring this component should verify that their system architecture supports the HCSL output standard and the specified 3.135V to 3.465V power rail. The 56-pin TFSOP footprint requires appropriate PCB layout considerations for thermal management and signal integrity at frequencies up to 400MHz. Since the part is obsolete, alternative components must be evaluated for pin compatibility and electrical parameter alignment.
