Device families and classification SPLDs (simple PLDs), CPLDs (complex PLDs), and FPGAs (field-programmable gate arrays) all belong to which broader class of reconfigurable digital devices?

Introduction / Context:
This question checks your understanding of how common reconfigurable logic device families are categorized. Knowing the umbrella term for SPLDs, CPLDs, and FPGAs helps you navigate datasheets, select parts, and communicate architecture choices in digital design projects.

Given Data / Assumptions:

• SPLD stands for simple programmable logic device.
• CPLD stands for complex programmable logic device.
• FPGA stands for field-programmable gate array.
• We are classifying these by device type, not by the specific programming technology (for example, EEPROM, SRAM, antifuse).

Concept / Approach:
All three device classes allow the user to implement custom logic functions after manufacturing. The collective term used in textbooks and vendor literature is PLD, which stands for programmable logic device. PAL (programmable array logic) is a type of SPLD. EPROM and SRAM describe memory technologies, not device classes, even though some PLDs may internally use those technologies to store configuration.

Step-by-Step Solution:

Verification / Alternative check:
Check any vendor overview: product lines are typically organized into SPLDs, CPLDs, and FPGAs under the broader heading of PLDs, confirming the classification.

Why Other Options Are Wrong:

• PAL: A specific SPLD architecture, not the umbrella category.
• EPROM / SRAM: Memory technologies used to store data or configuration, not device families themselves.

Common Pitfalls:
Confusing device class (PLD) with configuration technology (for example, EEPROM or SRAM). Another mistake is assuming PAL equals all PLDs; PAL is only one historical variant.

Final Answer:
PLD
