Package pin count (device family example) For the EPF10K70/EDF10K70 device family (a member of classic 10K-series programmable logic), which of the following standard package options matches a commonly available pin count?

Introduction / Context:
Programmable logic devices are offered in multiple packages (PQFP, TQFP, BGA, etc.), each with different pin counts, pitch, and thermal characteristics. Recognizing a typical pin count for a given density device helps with footprint selection, I/O planning, and board-level integration during early design stages.

Given Data / Assumptions:

• The device referenced belongs to the 10K-series family (for example, EPF10K70/EDF10K70), historically available in multiple package options.
• Common package choices for mid-density parts include ~208–256 pin QFP/TQFP or similar counts, with higher-end variants in larger BGAs.
• We select the pin count that aligns with a widely used, practical package for that class of device.

Concept / Approach:
Mid-range programmable logic from this family was frequently offered in packages around the 240-pin range for designs needing significant I/O while balancing cost and PCB complexity. While alternate packages may exist, choosing the commonly cited 240-pin option aligns with standard reference designs and evaluation boards from that era.

Step-by-Step Solution:

Verification / Alternative check:
Historical datasheets and board designs for 10K-series parts list multi-hundred-pin packages with 200–256 pins as prevalent; 240 aligns with those offerings.

Why Other Options Are Wrong:

• 70 / 140: Too few pins for the I/O needs of this density.
• 532: Much higher than typical for this family and era, more aligned with very large BGAs in newer families.

Common Pitfalls:
Assuming a single, unique pin count per device; in reality, multiple packages may exist. Here we select a representative, commonly used option consistent with the series capabilities.

Final Answer:
240
