AFS250-1PQG208I

Overview

The AFS250-1PQG208I is a Fusion mixed-signal FPGA featuring 250,000 system gates and 6,144 tiles. It operates within a voltage range of 3.3 V with an on-chip 1.5 V regulator. The device supports up to 114 digital I/Os and includes 2 Mbits of embedded flash memory alongside 36 kbits of SRAM. It integrates a 12-bit ADC with up to 18 analog input channels and six MOSFET gate driver outputs. Operating at speed grade 1, it functions in commercial (0°C to +85°C) or industrial (-40°C to +100°C) temperature ranges.

Feature Summary

• Integrates high-performance reprogrammable flash technology for instant-on operation without external boot PROMs.
• Combines digital logic with analog peripherals including a 12-bit ADC and programmable MOSFET gate drivers.
• Provides robust security through FlashLock and 128-bit AES encryption for IP protection.
• Supports mixed-voltage I/O standards across multiple banks for flexible interface compatibility.

Applications

• Power management systems
• Smart battery charging circuits
• Clock generation and management

Procurement Notes

Verify the specific suffix requirements for package type and temperature grade when ordering. Confirm that the selected variant matches the required operating environment and pinout specifications. Ensure compliance with RoHS directives if applicable. Check for any active engineering change notices related to this part number before finalizing procurement plans.

Selection Notes

Select this model for applications requiring integrated analog control alongside programmable logic. Consider the 2 Mbit flash capacity and 114 I/O limit against design complexity. Evaluate the need for the specific speed grade relative to timing constraints. Verify that the PQG208 package fits the available PCB real estate and thermal requirements.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs. It shares architectural similarities with other Fusion devices like the AFS090 and AFS600 but offers a mid-range density of 250,000 gates. The PQG208 package provides a plastic quad flat pack form factor suitable for surface mount assembly.

Replacement Considerations

Direct replacements within the same package and functionality include other AFS250 variants with different speed grades or temperature ratings. Cross-family migration may require significant redesign due to differences in analog integration and logic architecture.
