A1020B-PLG44I

Field Programmable Gate Array Overview

The A1020B-PLG44I is an embedded Field Programmable Gate Array (FPGA) IC from the Microsemi ACT™ 1 series. It features a logic density of 2000 gates and contains 547 Configurable Logic Blocks (CLBs). The device provides 34 available Input/Output pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 44-LCC package with J-leads, measuring 16.59x16.59 mm. The component supports surface mount installation and functions reliably across an operating temperature range of -40°C to 85°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing 2000 gates and 547 CLBs for flexible logic implementation
• CMOS technology supporting standard 5V operation within specified voltage limits
• 44-pin Leadless Chip Carrier package designed for surface-mount applications

Field Programmable Gate Array Applications

• General-purpose digital logic prototyping
• Interface bridging between different voltage domains or protocols
• Custom state machine and control logic implementation

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to 85°C) rather than commercial grade. Confirm the package type matches the 44-LCC specification with J-leads. Check current availability status as older ACT series components may be discontinued or limited in stock. Ensure compatibility with existing design tools for the ACT 1 family.

Field Programmable Gate Array Selection Notes

Select this model when 2000 gate capacity and 34 I/Os are sufficient for the design requirements. Compare against the A1020B-1PLG44C if a commercial temperature range is acceptable instead of industrial. Consider the 44-LCC footprint constraints during PCB layout. Verify that the 5V supply rail aligns with the system power architecture.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT™ 1 FPGA family, which offers mid-range programmable logic solutions. The A1020B variant specifically denotes the 2000-gate density level within this series. It serves as a legacy option for designs requiring CMOS-based FPGAs with established toolchains.

Field Programmable Gate Array Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip official resources for cross-reference information or modern replacements within the SmartFusion or IGLOO families.
