PCI1520PDV — PCI-to-CardBus bridge controller
The Texas Instruments PCI1520PDV is a PCI CardBus controller that bridges a PCI bus to PC Card slots, compliant with PC Card 7.1.
Supply and temperature — what they mean for the BOM
Runs on either 3.3 V or 5 V supply, which means it can sit on a mixed-voltage PCI bus without a separate level shifter. The 0°C to 70°C commercial temperature range limits it to indoor, climate-controlled equipment — office PCs, test instrumentation, rack-mount telecom gear. Not rated for industrial or automotive environments where the ambient might push past 70°C.
Lifecycle and sourcing reality
Texas Instruments lists this part as Active — no end-of-life notice, no last-time-buy window. That makes it a safe BOM line for production runs today and through the next several years. It is ROHS3 compliant, so no exemption paperwork needed for EU markets.
