What this controller does on the bus
The PCI1510ZWS is a single-slot PC CardBus controller that bridges the PCI bus to CardBus cards, handling the protocol translation and power management for one slot.
Package and board-fit checklist
Housed in a 144-ball LFBGA (12x12 mm body), the PCI1510ZWS uses a 0.80 mm ball pitch — a standard 4-layer PCB with via-in-pad or microvia fan-out handles the breakout without signal integrity issues at PCI clock rates. The supplier device package is 144-NFBGA, meaning the balls are on a 0.80 mm grid and the die sits on a laminate substrate that matches standard reflow profiles for lead-free assembly.
Temperature grade and operating envelope
The dual supply rails (3.3 V core, 5 V I/O) let it interface directly with legacy 5 V PCI buses while keeping the core logic at the lower voltage for reduced power dissipation.
