MAX7000S EPM7128S package pin count: An Altera EPM7128S device packaged in a PQFP with the stated I/O breakout (12 I/O per LAB plus 4 additional input-only pins) results in a total of how many package pins?

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:

• EPM7128S = MAX7000S family CPLD.
• The package is described as PQFP (plastic quad flat pack).
• Stated I/O mapping yields a total pin count commonly associated with a 100-pin package option.

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
