AFS250-1PQG208

Overview

The Microsemi AFS250-1PQG208 is a Fusion mixed-signal FPGA featuring 250,000 system gates and 6,144 tiles. It operates at a maximum digital frequency of 350 MHz within the PQ208 package. The device integrates 2 Mbits of user flash memory and 1 Kbit of FlashROM. It includes an ADC with up to 12-bit resolution and 600 Ksps sampling rate across 18 analog input channels. Power is supplied via a single 3.3 V source with an on-chip 1.5 V regulator. The industrial temperature grade (-40°C to +100°C) ensures reliable operation in demanding environments.

Feature Summary

• Integrates nonvolatile flash-based FPGA fabric with advanced analog peripherals for mixed-signal applications.
• Provides Instant On capability without external boot PROMs, eliminating configuration delays and reducing bill-of-materials costs.
• Includes integrated security features such as FlashLock and 128-bit AES decryption to protect intellectual property.
• Supports high-voltage tolerant I/O and programmable MOSFET gate drivers for direct power management control.

Applications

• Power management systems and smart battery charging
• Motor control applications requiring analog sensing
• Clock generation and management circuits
• Industrial system supervision and monitoring

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the component meets all required environmental specifications for the intended deployment environment. Ensure compatibility with existing design tools and verify pin assignments before finalizing procurement decisions.

Selection Notes

Select this model when a single-chip solution combining logic, memory, and analog functions is required. Consider the 250,000 gate density and 18 analog channels for moderate complexity designs. Evaluate the PQ208 package constraints against board space limitations. Compare performance metrics against higher-density Fusion devices if additional logic resources are anticipated.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs. It utilizes a 130-nm flash-based CMOS process. The AFS250 variant offers a balance of logic density and analog integration. It shares architectural similarities with other Fusion devices but provides specific resource counts tailored for mid-range applications.

Replacement Considerations

Consult official Microsemi documentation for verified cross-reference part numbers. Ensure any substitute maintains equivalent flash technology, analog channel counts, and package dimensions. Verify that replacement components support the same speed grades and security features.
