AFS250-PQG208

Overview

The AFS250-PQG208 is a Fusion mixed-signal FPGA featuring 250,000 system gates and 6,144 tiles. It operates on a single 3.3 V supply with an internal 1.5 V regulator. The device includes 2 Mbits of embedded flash memory and 36 kbits of SRAM. It supports up to 18 analog input channels via a 12-bit ADC with 600 Ksps sampling rate. The PQG208 package provides 93 digital I/Os and 26 analog I/Os across four banks. Operating temperature ranges from -40°C to +100°C for the industrial grade.

Feature Summary

• Integrates nonvolatile flash-based FPGA fabric with analog peripherals for instant-on operation without external boot PROMs.
• Includes a 12-bit ADC with high-voltage tolerance and programmable gate driver outputs for direct power management control.
• Provides hardware security through FlashLock and AES-128 encryption to protect intellectual property during in-system programming.

Applications

• Power management and smart battery charging systems
• Motor control applications requiring integrated analog sensing
• Clock generation and management circuits

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range (-40°C to +100°C). Confirm the package type PQG208 matches the required footprint. Check current availability status as legacy flash FPGA lines may have limited stock or end-of-life notices.

Selection Notes

Select this model when a single-chip solution combining logic, flash memory, and analog signal conditioning is required. Ensure the design utilizes the 3.3 V single-supply architecture. Verify that the 2 Mbit flash capacity meets the configuration and data storage needs.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs. It shares architectural similarities with the AFS090, AFS600, and AFS1500 models within the same series. The device leverages a 130-nm flash CMOS process for high integration and low power consumption.

Replacement Considerations

Compatible replacements within the same family include the AFS090 for lower density requirements or the AFS600 for higher logic capacity. Pin-compatible packages exist within the Fusion series, but verify speed grades and analog channel counts match the application requirements.
