Difficulty: Easy
Correct Answer: 100-pin
Explanation:
Introduction / Context:
EPM7128S belongs to Altera’s MAX7000S CPLD family. When selecting a device, designers must match I/O requirements to package options. The problem references a specific breakout pattern that totals to a well-known package size for this part.
Given Data / Assumptions:
Concept / Approach:
The question provides enough hints to identify the package size. MAX7000S devices, including EPM7128S, were widely available in 100-pin PQFP configurations suitable for mid-range I/O counts while maintaining manageable PCB footprint and pitch.
Step-by-Step Solution:
Verification / Alternative check:
Historic datasheets and distributor listings show EPM7128S availability in a 100-pin PQFP among other packages, validating the total pin count.
Why Other Options Are Wrong:
Common Pitfalls:
Assuming pin count scales directly with macrocell count across families; overlooking vendor-specific package availability.
Final Answer:
100-pin
