Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current product plan to confirm availability. Ensure the package type matches the required pin count and form factor. Check for any end-of-life notifications or obsolescence warnings associated with this legacy component series before finalizing procurement decisions.

Field Programmable Gate Array Selection Notes

Select this device when a small-scale FPGA with nonvolatile configuration is required. Consider the 44-pin package constraint for board space. Evaluate the 1200 gate capacity against design complexity. Verify that the 5V operating voltage aligns with system power rails. Confirm that the commercial temperature range meets environmental requirements.

Field Programmable Gate Array Part Context

This component belongs to the ACT 1 Series of FPGAs, which were among the first commercially available field-programmable gate arrays. The series is characterized by its use of antifuse technology rather than volatile SRAM or flash configurations. It represents an early generation of reprogrammable logic devices designed for rapid prototyping and low-volume production applications.

Field Programmable Gate Array Replacement Considerations

Direct replacements are limited due to the proprietary PLICE antifuse architecture. Review Actel/Microsemi successor families such as the ProASIC or SmartFusion series for modern equivalents. Verify pin compatibility and logic resource scaling when migrating to newer technologies.

Field Programmable Gate Array FAQ

What is the function of the PRA and PRB pins?

The PRA and PRB pins serve as independent diagnostic probe outputs. They allow users to observe any two internal signals in real-time during debugging. These pins can also function as standard user-defined I/Os after debugging is complete.

How does the ACT 1 Series achieve nonvolatile configuration?

The device uses Actel’s patented PLICE antifuse technology. Programming involves blowing specific antifuses to create permanent connections between logic modules and routing tracks. This process retains the programmed design without requiring external memory or power.

What is the maximum data rate for the standard speed grade?

For the standard speed grade, the maximum data rate is 75 MHz when operating at 5V. The maximum clock frequency for flip-flops is specified as 70 MHz under worst-case commercial conditions.
