A3PN125-1VQ100I

Overview

The A3PN125-1VQ100I is a ProASIC3 nano field-programmable gate array (FPGA) manufactured by Microchip Technology. It features 125,000 system gates and 71 user I/Os within a 100-VQFP package. The device operates on a core supply voltage ranging from 1.425 V to 1.575 V and supports a maximum system frequency of 350 MHz. It includes 36,864 bits of total RAM for embedded memory applications. The component is rated for an industrial operating temperature range of -40°C to +100°C (TJ).

Feature Summary

• Flash-based non-volatile architecture enabling instant-on functionality without external configuration memory.
• Supports mixed-voltage I/O banks allowing operation with 1.5 V, 1.8 V, 2.5 V, and 3.3 V standards.
• Integrated Clock Conditioning Circuit (CCC) blocks with phase shift and multiply/divide capabilities.

Applications

• Industrial control systems requiring deterministic logic processing.
• Communication interface bridging between different voltage domains.
• Secure hardware implementations utilizing in-system programming with AES decryption.

Procurement Notes

Verify the suffix 'I' confirms the extended industrial temperature range (-40°C to +100°C). Confirm RoHS status as this specific part may not be compliant depending on manufacturing date. Check for moisture sensitivity level requirements during storage and handling. Ensure the 100-VQFP footprint matches the target PCB design constraints.

Selection Notes

Select this model when 125k gates and 36 kbits of SRAM are required in a QFP package. Compare against A3P125 if lower cost commercial grade is sufficient. Consider A3PN250 for higher density needs. Verify I/O voltage compatibility with connected peripherals before finalizing the bill of materials.

Part Context

This component belongs to the ProASIC3 nano family, designed for low-power, high-density applications. It bridges the gap between standard ASICs and larger FPGAs, offering reprogrammability with flash reliability. The series emphasizes security and instant-on capabilities for embedded logic solutions.

Replacement Considerations

A3PN125-1VQ100 is the commercial grade equivalent with a limited temperature range. A3PN125-Z1VQG100I offers a different package variant. Direct pin-compatible upgrades within the ProASIC3 nano family should be verified against specific electrical parameter differences.
