A1020B-CQ84C

Field Programmable Gate Array Overview

The A1020B-CQ84C is an embedded Field Programmable Gate Array (FPGA) IC from the Microsemi ACT™ 1 series. It features a logic capacity of 2000 gates organized into 547 LAB/CLB blocks. The device provides 69 user-programmable I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 84-PLCC package with dimensions of 29.31x29.31 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 single-chip ASIC alternative capabilities
• Configurable logic blocks for custom digital circuit implementation
• Mixed-voltage operation support for core and I/Os

Field Programmable Gate Array Applications

• Digital signal processing systems
• Custom interface logic adaptation
• Prototyping for ASIC designs

Field Programmable Gate Array Procurement Notes

Verify the specific suffix against official Microsemi documentation, as standard ACT 1 listings often use PLG or VQG packages. Confirm end-of-life status via manufacturer PCN notices, as many ACT 1 variants were discontinued around June 2013. Ensure compatibility with existing board footprints for 84-pin plastic leaded chip carriers before procurement.

Field Programmable Gate Array Selection Notes

Select this model when 2000 gate density and 69 I/Os are required in a compact 84-pin form factor. Compare against the A1010B for lower density needs or the A1020B-1PLG84C if commercial temperature grades suffice. Verify that the C suffix aligns with the intended manufacturing process revision and packaging specifications defined in the official datasheet.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 family, which bridges the gap between discrete logic and full ASICs. The ACT 1 series utilizes CMOS technology to offer reprogrammability with performance comparable to fixed logic. The A1020B variant represents a mid-range density option within this legacy portfolio, designed for applications requiring flexible logic resources in a small footprint.

Field Programmable Gate Array Replacement Considerations

Official direct replacements may be unavailable due to discontinuation. Consider the A1020B-1PLG84C for identical electrical characteristics in a PLCC package. For pin-compatible alternatives, evaluate modern FPGA families from Microsemi or other vendors, ensuring logic density and I/O voltage levels match the original design requirements.
