A3P125-2QNG132I

Field Programmable Gate Array Overview

The Microsemi A3P125-2QNG132I is a ProASIC3 Flash FPGA featuring 125,000 system gates and 3,072 VersaTiles. It utilizes a 130-nm flash process with a maximum system performance of 350 MHz. The device includes 36 Kbits of embedded SRAM and 1 Kbit of nonvolatile FlashROM. It operates in an industrial temperature range (-40°C to +100°C) and supports AES-based In-System Programming security. The QN132 package provides 132 pins with up to 133 user I/Os.

Field Programmable Gate Array Feature Summary

• Nonvolatile flash architecture enables instant-on operation without external configuration memory.
• Integrated AES decryption engine secures intellectual property during remote field updates.
• Versatile VersaTile core supports configurable logic functions and flip-flops for high utilization.
• Flexible clock conditioning circuits include PLL capabilities for precise phase and frequency synthesis.

Field Programmable Gate Array Applications

• Secure remote firmware updates over public networks
• Industrial control systems requiring instant power-up
• Avionics and computing applications needing IP protection

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix '2' indicates a 25% faster performance tier compared to standard devices. Confirm the 'I' suffix denotes the industrial temperature range requirement. Ensure the QN132 package dimensions match the target PCB footprint constraints. Check for RoHS compliance status associated with the 'G' packaging option if applicable to the full part number.

Field Programmable Gate Array Selection Notes

Select this model for designs requiring 125K gates with industrial reliability. The QN132 package offers a balance of pin count and board area. Consider the -2 speed grade only if timing closure at higher frequencies is necessary. Verify that the embedded SRAM capacity meets buffering requirements before choosing lower-density alternatives.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ProASIC3 Flash family, which bridges the gap between CPLDs and complex FPGAs. It serves as a cost-effective ASIC replacement for low-to-medium volume production runs. The family emphasizes security and nonvolatility, distinguishing it from volatile SRAM-based FPGA competitors.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitutes within the same density class include the A3P125-1QNG132I (standard speed) or A3P125-FG144 variants (different package). Cross-family migration to ProASIC3E may be required for enhanced features or higher densities.
