AFS250-1PQ208I

Overview

The Microsemi AFS250-1PQ208I 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 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 a single 3.3 V supply with an on-chip 1.5 V regulator. The industrial temperature grade (-40°C to +100°C) ensures reliability in harsh environments.

Feature Summary

• Instant On nonvolatile flash architecture eliminates external boot PROM requirements
• Integrated 12-bit ADC with high-voltage tolerance for mixed-signal applications
• Hardware AES decryption engine with FlashLock security for IP protection
• On-chip clocking resources including PLLs and real-time counter

Applications

• Power management and smart battery charging systems
• Motor control and gate driver applications
• Clock generation and distribution networks
• Industrial system supervision and monitoring

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the -1 speed grade meets the required timing constraints for the target design. Ensure the PQ208 package dimensions align with the PCB footprint specifications. Check for any relevant RoHS compliance certifications if required by the manufacturing facility standards.

Selection Notes

Select this component when a single-chip solution combining logic, flash memory, and analog peripherals is necessary. The AFS250 offers sufficient density for moderate complexity designs requiring instant-on capabilities. Consider the integrated ADC and gate drivers if discrete analog components can be replaced. Verify that the 2 Mbit flash capacity accommodates the complete configuration bitstream and data storage needs.

Part Context

This part belongs to the Microsemi Fusion family of mixed-signal FPGAs. It shares architectural similarities with the AFS090, AFS600, and AFS1500 devices within the same series. The PQ208 package is pin-compatible with other Fusion devices in similar form factors, facilitating board layout reuse across different density options within the family.

Replacement Considerations

Direct pin-compatible replacements within the Fusion family include the AFS090 and AFS600 variants in the PQ208 package. Verify functional equivalence regarding I/O counts and memory sizes when substituting. Cross-family migration to ProASIC3 or SmartFusion requires significant redesign due to architectural differences.
