AFS250-PQ208I

Overview

The Microsemi AFS250-PQ208I is a Fusion mixed-signal FPGA featuring 250,000 system gates and 6,144 tiles. It utilizes an advanced 130-nm flash-based CMOS process with seven metal layers. The device includes 2 Mbits of embedded user flash memory and 1 Kbit of FlashROM. It integrates a 12-bit ADC supporting up to 600 Ksps sampling rate across 18 analog input channels. The PQ208 package provides 93 single-ended or 26 differential digital I/Os. Operating voltage ranges from 3.3 V with an on-chip 1.5 V regulator. The industrial temperature grade (-40°C to +100°C) ensures reliability in demanding environments.

Feature Summary

• Integrates high-performance flash-based FPGA fabric with mixed-signal analog peripherals on a single chip.
• Provides instant-on operation without external configuration boot PROMs due to nonvolatile flash architecture.
• Includes integrated analog-to-digital conversion with high-voltage tolerance and programmable MOSFET gate drivers.
• Supports secure in-system programming using 128-bit AES encryption and FlashLock technology.

Applications

• Power management systems and smart battery charging controllers
• Clock generation and distribution networks
• Motor control applications requiring mixed-signal integration

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature range specification. Confirm the package type matches the required PCB footprint for the PQFP-208 form factor. Ensure design tools support the Fusion family architecture for proper configuration and analog peripheral setup.

Selection Notes

Select this model when a balance of logic density and analog integration is required. The 250,000 gate count suits moderate complexity designs. Verify that the 2 Mbit flash capacity meets storage needs for both configuration and user data. Check if the specific I/O count fits the interface requirements.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs. It shares architectural similarities with other devices in the series, such as the AFS090 and AFS600, but offers distinct resource scaling. The PQ208 package is a standard plastic quad flat pack option within this product line.

Replacement Considerations

Direct pin-compatible replacements within the same package include other Fusion devices like the AFS090 or AFS600, subject to logic and memory resource constraints. Verify software compatibility and feature parity before substitution.
