AFS250-PQ208

Overview

The AFS250-PQ208 is a Fusion mixed-signal Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 250,000 system gates and 6,144 tiles within a 208-pin Plastic Quad Flat Pack (PQFP) package with a 0.5 mm pitch. The device operates on a single 3.3 V supply utilizing an on-chip 1.5 V regulator. Key specifications include 2 Mbits of embedded flash memory, 36 kbits of SRAM, and an integrated 12-bit Analog-to-Digital Converter (ADC) supporting up to 18 analog input channels. It supports commercial temperature ranges from 0°C to +85°C.

Feature Summary

• Integrates high-performance flash-based FPGA fabric with advanced analog peripherals for mixed-signal applications.
• Provides Instant On capability without external configuration boot PROMs, ensuring immediate operation upon power application.
• Includes robust security features such as FlashLock and 128-bit AES encryption for IP protection and secure in-system programming.
• Features an integrated 12-bit ADC with multiple configurable input channels and dedicated MOSFET gate driver outputs.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with Libero SoC software tools for design implementation. Confirm RoHS compliance status if required for your manufacturing process. Check for any end-of-life notifications or alternative part recommendations from Microsemi.

Selection Notes

Select this component when a single-chip solution combining digital logic, nonvolatile memory, and analog conversion is required. The AFS250 offers sufficient density for moderate complexity designs while reducing bill-of-materials costs compared to discrete solutions. Consider the PQ208 package only if pin count and form factor constraints align with the 208-lead footprint.

Part Context

This device belongs to the Fusion family of mixed-signal FPGAs, which combines ProASIC3 flash architecture with analog blocks. It is distinct from standard SRAM-based FPGAs due to its nonvolatile nature and integrated analog capabilities. The AFS250 serves as a mid-range option within the family, balancing gate density with analog resource availability.

Replacement Considerations

Pin-compatible alternatives within the Fusion family include the AFS090 and AFS600, though they differ significantly in gate count and resource allocation. Verify that any substitute maintains the required 208-pin PQFP package and meets the specific voltage and temperature operating conditions of the original design.
