A54SX32A-2TQG176

Overview

The A54SX32A-2TQG176 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates with a maximum internal clock frequency of 350 MHz and supports up to 147 user-programmable I/O pins in a 176-pin Thin Quad Flat Pack (TQFP) package. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Provides deterministic timing through user-controllable routing resources including DirectConnect and FastConnect
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG)
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• High-performance digital signal processing requiring low-latency interconnects
• Systems requiring nonvolatile configuration without external memory

Procurement Notes

Verify the specific speed grade suffix '2' indicates approximately 25% faster performance than standard speed. Confirm the temperature grade suffix 'I' corresponds to industrial range (-40°C to +85°C). Ensure the ordering code matches the 176-pin TQFP package type for physical compatibility.

Selection Notes

Select this component when designs require 48,000 system gates with high-speed internal performance up to 350 MHz. Consider the 176-pin TQFP package if board space constraints favor thin profiles over BGA options. Verify that the 147 available user I/Os meet interface requirements for the target application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The SX-A series is designed for cost-effective, single-chip integration of CPLD and FPGA functionalities, offering high reliability and security features compared to volatile SRAM-based FPGAs.
