A54SX72A-1PQG208

Overview

The A54SX72A-1PQG208 is a nonvolatile, single-chip Field Programmable Gate Array (FPGA) from the Actel SX-A family. It provides 108,000 system gates and supports up to 360 user-programmable I/O pins. The device operates with internal clock frequencies up to 350 MHz and delivers 250 MHz system performance. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The part number suffix indicates a standard speed grade (-1), a Plastic Quad Flat Pack package with 208 leads (PQ208), and commercial temperature range operation (0°C to +70°C).

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing.
• Includes dedicated quadrant clocks for localized high-speed clock distribution.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1.

Applications

• High-performance logic integration requiring deterministic timing.
• Systems requiring hot-swappable interface capabilities.
• PCI-compliant designs operating at 66 MHz.
• Applications needing secure, nonvolatile configuration without external bitstreams.

Procurement Notes
