Understanding GAL22V10 capabilities: Which statement correctly characterizes the GAL22V10 programmable logic device?

Introduction / Context:
The GAL22V10 is a classic Generic Array Logic device widely used in embedded and digital systems as a pin-compatible, reprogrammable upgrade to earlier PAL parts. Choosing the correct description helps learners anchor its place in the taxonomy of programmable logic.

Given Data / Assumptions:

• “GAL” indicates EEPROM-based, reprogrammable SPLD.
• “22V10” suggests input capacity and 10 configurable macrocells for outputs/registered functions.
• The device predates modern software “downloads” as a descriptor of the hardware itself.

Concept / Approach:
Classify by device family first: GAL devices are SPLDs (Simple Programmable Logic Devices). Then evaluate the misleading numeric interpretations. Although 22V10 relates to architecture, saying “has 10 inputs and 22 outputs” reverses the intent. Equally, “32 inputs and 10 outputs” is not the standard naming meaning and is not a canonical spec.

Step-by-Step Solution:

Verification / Alternative check:
Datasheets and tutorials uniformly list GAL22V10 under SPLD family devices.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming naming directly equals fixed I/O counts; overlooking macrocell configurability.

Final Answer:
is a type of SPLD
