AFS250-2PQ208I

Overview

The AFS250-2PQ208I is a Fusion mixed-signal Field Programmable Gate Array 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 maximum system performance of 350 MHz and includes 2 Mbits of embedded user flash memory alongside 1 Kbit of FlashROM. It integrates a 12-bit ADC capable of up to 600 Ksps sampling rate across 18 analog input channels. The component operates within a commercial temperature range of 0°C to +85°C and is housed in a PQFP-208 package.

Feature Summary

• Instant On nonvolatile flash architecture eliminates external boot PROM requirements
• Integrated 12-bit ADC with high-voltage tolerance for mixed-signal applications
• Hardware AES decryption engine with FlashLock security for IP protection
• Single 3.3V power supply operation with on-chip voltage regulation

Applications

• Power management and smart battery charging systems
• Clock generation and distribution networks
• Motor control circuits
• System supervisor and management functions

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required 25% faster timing specification relative to standard devices. Confirm the 'I' suffix indicates the intended industrial temperature rating if applicable, though datasheet tables list PQ208 availability primarily under commercial grades for this density. Ensure the ordering code matches the exact pinout and package dimensions defined for the PQFP-208 form factor.

Selection Notes

Select this model when a single-chip solution integrating digital logic, analog sensing, and nonvolatile memory is required. The AFS250 offers sufficient gate density for moderate complexity designs while providing dedicated analog quads for signal conditioning. Consider the 350 MHz performance limit and 2 Mbit flash capacity against larger family members like the AFS600 if higher resource utilization is anticipated.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs, which combines flash-based programmable logic with analog peripherals. The AFS250 variant sits between the lower-density AFS090 and the higher-capacity AFS600 in terms of system gates and tile count. It shares architectural similarities with ARM Cortex-M1 enabled variants but lacks the integrated soft processor core.
