AFS250-2PQG208I

Overview

The AFS250-2PQG208I is a Fusion mixed-signal Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 250,000 system gates and 6,144 tiles within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates on a single 3.3 V supply with an internal 1.5 V regulator and supports an industrial temperature range of -40°C to +100°C. Key specifications include 2 Mbits of embedded flash memory, 36 kbits of SRAM, and a 12-bit Analog-to-Digital Converter (ADC) capable of up to 600 Ksps sampling rate.

Feature Summary

• Integrates nonvolatile flash-based FPGA fabric with analog peripherals for instant-on operation without external configuration boot PROMs.
• Includes a 12-bit ADC with up to 30 scalable analog input channels and high-voltage tolerance for mixed-signal applications.
• Provides advanced security through FlashLock technology and 128-bit AES encryption for in-system programming and IP protection.

Applications

• Power management and smart battery charging systems
• Motor control and industrial automation
• Clock generation and management circuits

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required performance metrics for your design. Confirm that the PQG208 package type matches your PCB footprint requirements. Ensure the 'I' suffix aligns with the necessary industrial temperature operating range. Check current availability status as legacy flash FPGA lines may have limited stock or end-of-life notices.

Selection Notes

Select this model when a single-chip solution combining digital logic, flash memory, and analog conversion is required. The 250,000 gate count suits mid-range complexity designs. Consider the integrated ADC and MOSFET drivers if discrete analog components can be eliminated. Verify pin compatibility if migrating from other Fusion family devices like the AFS090 or AFS600.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs, which combines flash-based programmability with analog capabilities. It shares architectural similarities with the ProASIC3 series but adds significant on-chip memory and analog blocks. The PQG208 package is a standard plastic quad flat pack option within this product line.

Replacement Considerations

Direct pin-compatible replacements within the same package include the AFS090 and AFS600, though gate counts and resource availability differ significantly. For higher density needs, consider the AFS1500. Cross-family migration to SmartFusion or IGLOO requires redesign due to architectural differences.
