A1020B-1PG84B

Field Programmable Gate Array Overview

The A1020B-1PG84B is an embedded Field Programmable Gate Array (FPGA) belonging to the ACT™ 1 series manufactured by Microsemi Corporation. This device features a logic capacity of 2000 gates organized into 547 Configurable Logic Blocks (CLBs). It provides 69 user-programmable input/output pins and operates within a supply voltage range of 4.5V to 5.5V. The component is housed in an 84-pin PLCC package with J-leads, measuring approximately 29.31x29.31 mm. It supports surface mount installation and functions at ambient temperatures between 0°C and 70°C.

Field Programmable Gate Array Feature Summary

• Configurable I/O structure supporting mixed-voltage operation capabilities
• On-chip configuration memory for non-volatile programming retention

Field Programmable Gate Array Applications

• Replacement for complex discrete logic circuits in industrial control systems
• Prototyping of custom ASIC designs for embedded applications
• Interface bridging between legacy digital components and modern processors

Field Programmable Gate Array Procurement Notes

Verify authenticity through authorized Microchip distributors due to discontinued status. Confirm date codes against known obsolescence notices issued in June 2013. Ensure storage conditions maintain moisture sensitivity level compliance prior to reflow soldering processes.

Field Programmable Gate Array Selection Notes

Compare pin counts and gate densities against ACT 3 or SmartFusion families for enhanced performance requirements. Evaluate thermal dissipation needs for the PLCC package in enclosed enclosures. Assess if higher speed grades are necessary for specific timing constraints compared to this -1 speed bin.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT 1 family, representing an early generation of flash-based FPGAs. It succeeded earlier EPROM-based devices by offering reprogrammability without UV erasure. The A1020 variant specifically targets mid-range logic density applications requiring moderate I/O counts.

Field Programmable Gate Array Replacement Considerations

Direct substitutes include other ACT 1 variants such as A1020B-1PLG84C or A1020B-1VQG80I depending on package preference. Modern replacements may involve Microchip IGLOO or SmartFusion2 series for improved power efficiency and integration.
