A1020B-2PL84I

Field Programmable Gate Array Overview

The A1020B-2PL84I is an ACT™ 1 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a logic density of 2000 equivalent gates organized into 547 Configurable Logic Blocks (CLBs). The device provides 69 user-accessible I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads, measuring 29.31x29.31 mm. The component supports surface mount installation and functions within an ambient temperature range of 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing high-density programmable logic with 547 CLBs
• CMOS technology enabling operation at standard 5V supply levels
• J-lead PLCC packaging designed for reliable surface-mount integration

Field Programmable Gate Array Applications

• General-purpose digital logic prototyping and implementation
• Industrial control systems requiring moderate I/O counts
• Embedded interface adaptation and protocol conversion

Field Programmable Gate Array Procurement Notes

Verify the specific suffix '2' indicates the speed grade and 'I' denotes the industrial temperature variant if applicable, though official datasheets for this exact part number are scarce. Confirm end-of-life status as the A1020B family was discontinued on June 21, 2013. Source components from authorized distributors or surplus suppliers only, ensuring authenticity checks are performed due to the age of the product line.

Field Programmable Gate Array Selection Notes

Select this component when a 2000-gate FPGA with 69 I/Os is required in an 84-pin PLCC form factor. Compare against the A1020B-1PL84I for lower speed grades or the A1020A variants for commercial temperature ranges. Ensure design tools support the legacy ACT™ 1 family constraints and pinout definitions before finalizing the bill of materials.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT™ 1 family, a CMOS-based FPGA series known for replacing complex discrete logic. The A1020B model represents a higher performance tier within the A1020 baseline, offering improved timing characteristics while maintaining compatibility with existing ACT™ 1 design flows and software environments.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Consider the A1020B-1PL84I for lower speed requirements or the A1020A-2PL84I for commercial temperature applications. Cross-reference with other ACT™ 1 variants for pin-compatible alternatives.
