A3PN250-VQ100

Overview

The A3PN250-VQ100 is a ProASIC3 nano Flash FPGA manufactured by Microchip Technology. It features 250,000 system gates and 3,000 logic elements within a 100-VQFP (14x14 mm) surface-mount package. The device includes 36,864 bits of embedded SRAM and supports 68 user I/Os. Operating voltage ranges from 1.425 V to 1.575 V, with a maximum operating frequency of 350 MHz. It functions within a temperature range of -20°C to +85°C.

Feature Summary

• Flash-based non-volatile technology enabling instant-on operation without external configuration memory.
• Supports mixed-voltage I/O standards including 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
• Integrates Clock Conditioning Circuits (CCC) with Phase-Locked Loops for clock management.
• Provides in-system programming capabilities via JTAG using AES decryption.

Applications

• Industrial control systems requiring low power and instant-on functionality.
• Telecommunications infrastructure utilizing mixed-voltage signaling.
• Test and measurement equipment needing reprogrammable logic.
• Automotive electronics operating within specified temperature ranges.

Procurement Notes

Verify the specific suffix 'VQ100' corresponds to the 100-pin VQFP package and commercial temperature grade (-20°C to +85°C). Confirm RoHS compliance status as some variants may differ. Check for recent PCNs regarding assembly or software updates that might affect pin compatibility or design files.

Selection Notes

Select this component when non-volatile flash configuration is required to eliminate external boot devices. Ensure the design fits within the 250k gate and 36 kbit RAM limits. Verify that the 68 available I/Os meet interface requirements and that the 350 MHz performance aligns with system timing constraints.

Part Context

This part belongs to the ProASIC3 nano family, which bridges the gap between ASICs and standard FPGAs by offering lower power consumption and smaller form factors. It shares pin compatibility with other ProASIC3 devices, facilitating design reuse across different capacity levels within the same package type.

Replacement Considerations

Direct pin-compatible substitutes include other members of the ProASIC3 family such as A3PN125 or A3PN250 variants with different temperature grades. Cross-family replacements require careful review of I/O mapping and power supply differences.
