A3P125-QNG132

Field Programmable Gate Array Overview

The A3P125-QNG132 is a ProASIC3 Flash FPGA featuring 125,000 system gates and 3,072 VersaTiles. It includes 36 kbits of embedded True Dual-Port SRAM and 1 kbit of nonvolatile FlashROM. The device supports up to 81 user I/Os in the QN132 package and operates at a maximum frequency of 350 MHz. Power requirements range from 1.425 V to 1.575 V. It functions within an industrial temperature range of -40°C to +100°C.

Field Programmable Gate Array Feature Summary

• Nonvolatile flash technology enables instant-on operation without external boot PROMs.
• Integrated AES decryption engine provides secure in-system programming and IP protection.
• Versatile VersaTile architecture supports LUT-3 logic, D-flip-flops, and latches.
• Flexible clock conditioning circuits include six CCC blocks with one integrated PLL.

Field Programmable Gate Array Applications

• Secure remote field updates over public networks
• System initialization and critical task execution before processor wake-up
• Storage of calibration settings and device serialization data

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +100°C). Confirm the 'G' suffix denotes lead-free, RoHS-compliant packaging. Ensure the QN132 package dimensions match the design footprint requirements for the target PCB layout.

Field Programmable Gate Array Selection Notes

Select this device for designs requiring nonvolatile configuration and moderate logic density. Verify that the 81 available user I/Os meet interface requirements. Consider the 350 MHz performance limit for timing closure. Check if ARM Cortex-M1 support is needed, as it requires a different part number prefix.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ProASIC3 Flash family, designed as a cost-effective ASIC replacement. It utilizes a 130-nm process with seven metal layers. The family offers high-density programmable logic with low power consumption and inherent security features against invasive attacks.

Field Programmable Gate Array Replacement Considerations

Check for pin-compatible packages within the ProASIC3 family such as FG144 or TQ144 variants. Higher density devices like A3P250 may offer more I/Os but require verification of package availability and power constraints.

Field Programmable Gate Array FAQ

Does the A3P125 support ARM Cortex-M1 processors?

No, the standard A3P125 does not support ARM processors. Devices with ARM support have the M1A3P prefix (e.g., M1A3P250).

What is the purpose of the on-chip FlashROM?

The 1 kbit FlashROM stores nonvolatile data such as IP addressing, calibration settings, serial numbers, and secure keys.

How many global clock networks are available?

The device provides six chip (main) and three quadrant global VersaNets for low-skew clock distribution.
