AFS250-2PQ208

Overview

The AFS250-2PQ208 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 supports a single 3.3 V power supply with an on-chip 1.5 V regulator. It includes 2 Mbits of embedded user flash memory and 1 Kbit of FlashROM. The integrated ADC offers up to 12-bit resolution at 600 Ksps with 18 analog input channels. Digital I/Os support mixed-voltage operation from 1.5 V to 3.3 V. The package is a 208-pin Plastic Quad Flat Pack (PQFP) with a 0.5 mm pitch.

Feature Summary

• Instant On nonvolatile flash architecture eliminates external boot PROM requirements.
• Integrated analog peripherals include a high-resolution ADC and MOSFET gate drivers.
• Advanced security features provide AES decryption and FlashLock protection for IP.
• Single 3.3 V supply operation simplifies power management and reduces board space.

Applications

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

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required 25% faster performance tier relative to standard devices. Confirm the 'I' or blank suffix matches the required junction temperature range, as the PQ208 package availability varies by commercial and industrial grades. Ensure the ordering code aligns with RoHS compliance requirements if applicable.

Selection Notes

Select this model when a balance of moderate logic density and extensive analog integration is required. The PQ208 package provides a suitable pin count for mixed-signal designs without the complexity of BGA packages. Consider the -2 speed grade only if the design timing constraints necessitate the higher performance tier available in that specific variant.

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 distinct resource scaling. The AFS250 serves as a mid-range option within the series, providing sufficient resources for complex mixed-signal tasks while maintaining low power consumption characteristics inherent to flash technology.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to specific speed grade and temperature range variations. Review the AFS250 datasheet for alternative packages or speed grades that may fit the physical footprint if the exact -2PQ208 configuration is unavailable.
