A1415A-VQG100C

Field Programmable Gate Array Overview

The A1415A-VQG100C is an Actel ACT3 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a capacity of 200 Configurable Logic Blocks (CLBs) and approximately 1,500 equivalent gates. The device operates with a maximum clock frequency of 110 MHz and utilizes CMOS technology. It is housed in a 100-pin Thin Profile Quad Flat Package (TFQFP/VQFP-100) with a height of 1 mm. The component supports a supply voltage range of 4.5V to 5.5V and offers an industrial operating temperature range from -40°C to +85°C.

Field Programmable Gate Array Feature Summary

• ACT3 architecture providing high-performance logic density within a compact footprint
• Support for mixed-voltage I/O standards including LVTTL and LVCMOS
• Predictable performance through automatic place-and-route tools

Field Programmable Gate Array Applications

• Industrial control systems requiring reliable programmable logic
• Communication interface adapters and protocol converters
• Consumer electronics logic replacement and enhancement

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' against official Microsemi documentation to confirm it denotes the commercial temperature grade (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the VQFP-100 package. Confirm RoHS compliance status as historical Actel/Microsemi data may vary by production batch. Check for obsolescence notices or lifecycle status updates prior to procurement.

Field Programmable Gate Array Selection Notes

Select this model when a moderate logic density of 1,500 gates is sufficient for the design. The 110 MHz speed grade suits applications not requiring high-frequency processing. Compare against the A1415A-1PQG100I if an extended industrial temperature range (-55°C to +125°C) is required instead of the commercial grade. Ensure the design tool suite supports the legacy ACT3 family.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi (formerly Actel) ACT3 FPGA family, which bridges the gap between complex PLDs and larger FPGAs. The ACT3 series is known for its non-volatile flash-based technology, allowing instant-on functionality without external configuration memory. This specific part represents a mid-range density option within that portfolio.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements are limited due to the age of the ACT3 family. Consider the A1415A-1PQG100I for an industrial temperature variant. For modern equivalents, evaluate Microsemi's PolarFire or IGLOO families, though these require significant schematic and firmware redesign.
