A1020B-PLG68C

Field Programmable Gate Array Overview

The A1020B-PLG68C is an embedded Field Programmable Gate Array (FPGA) from the Microsemi ACT™ 1 series. It features 2000 system gates and 547 Logic Array Blocks (LABs). The device provides 57 user-programmable I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 68-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads, measuring 24.23x24.23 mm. The component supports surface mount installation and functions at ambient temperatures between 0°C and 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing high-capacity programmable logic for ASIC replacement
• Configurable dual-port SRAM blocks for embedded memory applications
• Fast wide-decode circuitry supporting complex logic implementations

Field Programmable Gate Array Applications

• High capacity single-chip ASIC alternative designs
• Mixed-voltage interface bridging between 5.0V and 3.3V domains
• Industrial control systems requiring deterministic timing

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' against official Microsemi documentation to confirm the commercial temperature rating and package variant. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity, as this component may be subject to obsolescence notices or production changes documented by the original equipment manufacturer.

Field Programmable Gate Array Selection Notes

Select this model when a 68-pin PLCC footprint is required for the ACT™ 1 family. Ensure the design accommodates the 4.5V to 5.5V power supply constraints. Verify that the 57 available I/O pins meet the interface requirements, noting that other variants like the A1020B-1VQG80I offer different pin counts and packages.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 FPGA family, which serves as a bridge between standard logic and custom ASICs. The A1020B variant specifically offers 2000 system gates, distinguishing it from lower-density parts like the A1010B. The PLG68 designation indicates the specific plastic leaded chip carrier package configuration used in this iteration.
