AFS250-1PQ208

Overview

The AFS250-1PQ208 is a Fusion mixed-signal Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 250,000 system gates and 6,144 configurable logic blocks (tiles). The device operates at a maximum clock frequency of 350 MHz and supports up to 114 digital I/Os within a 208-pin Plastic Quad Flat Pack (PQFP) package with a 0.5 mm pitch. It includes 2 Mbits of embedded flash memory, 36 kbits of SRAM, and an integrated 12-bit ADC supporting up to 18 analog input channels. The component functions on a single 3.3 V supply and is rated for commercial operation between 0°C and +85°C.

Feature Summary

• Integrates high-performance flash-based FPGA fabric with analog peripherals and nonvolatile memory on a single chip.
• Provides instant-on functionality without external configuration boot PROMs, eliminating power-on surges and reducing board space.
• Includes advanced security features such as FlashLock and 128-bit AES encryption for in-system programming and IP protection.
• Supports mixed-voltage digital I/O standards and features an integrated 12-bit ADC with multiple analog input channels.

Applications

• Power management systems and smart battery charging controllers
• Clock generation and management circuits
• Motor control applications requiring mixed-signal processing

Procurement Notes

Verify the specific speed grade suffix '1' corresponds to the required performance level against the datasheet matrix. Confirm the PQ208 package availability and ensure the commercial temperature range meets operational requirements. Check for RoHS compliance status and verify that the ordering code matches the exact pinout and security license options defined in the official Microsemi documentation.

Selection Notes

Select this model when a design requires immediate system startup without external configuration devices. Choose the AFS250 variant if the application needs approximately 250,000 system gates combined with analog sensing capabilities. Ensure the 2 Mbit flash capacity suffices for both logic configuration and user data storage needs.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs, which combines flash technology with analog peripherals. It shares architectural similarities with other Fusion devices like the AFS090 and AFS600 but offers a mid-range density of 250,000 gates. The PQ208 package provides a compact footprint suitable for space-constrained designs requiring mixed-signal integration.

Replacement Considerations

Direct pin-compatible replacements within the same package include other Fusion devices such as the AFS090 or AFS600, provided the gate count and I/O requirements align. Verify that any substitute maintains the 350 MHz performance grade and commercial temperature rating.
