A1020B-PQ100C

Field Programmable Gate Array Overview

The A1020B-PQ100C is an ACT™ 1 Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 2000 equivalent gates and 547 Logic Array Blocks (LABs). The device supports up to 69 user-programmable I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 100-pin Plastic Quad Flat Package (PQFP) with dimensions of 20x14 mm. The component is rated for commercial temperature operation between 0°C and 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing high-capacity single-chip ASIC alternative capabilities
• CMOS technology enabling low power consumption and high-speed performance
• In-system programmability allowing field updates without socket removal

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic logic processing
• Telecommunications interface prototyping and implementation
• Automotive electronics applications compatible with commercial temperature ranges

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PQ100' confirms the plastic quad flat package variant, as other suffixes indicate different packages like PLCC or VQFP. Confirm the 'B' revision status against the June 2013 Product Change Notification for A1010B/A1020B families. Check RoHS compliance status, as older ACT 1 devices may be non-compliant. Ensure the obsolete status is acceptable for new designs due to potential supply constraints.

Field Programmable Gate Array Selection Notes

Select this model when 2000 system gates and 547 LABs are required in a 100-pin surface-mount package. Compare against the A1010B series if lower gate counts suffice. Consider the A1020B-1PLG84C for smaller footprint requirements using PLCC packaging. Verify voltage compatibility with 5V logic systems, as the device requires 4.5V to 5.5V supply.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT™ 1 family, a legacy line of SRAM-based FPGAs. The A1020B designation indicates the 2000-gate density tier within this series. The family was widely used before being succeeded by SmartFusion and IGLOO technologies. The PQ100 package offers a balance of pin count and board space for mid-density applications.

Field Programmable Gate Array Replacement Considerations

Public confirmed substitutes include A1020B-1PLG84C (84-pin PLCC), A1020B-1VQG80I (80-pin VQFP), and A1020B-PLG68I (68-pin PLCC). These variants share identical logical specifications but differ in physical package dimensions and pin configurations.
