A54SX32A-1TQG176I

Overview

The A54SX32A-1TQG176I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

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

Applications

• High-performance digital logic integration requiring low power consumption
• Systems needing nonvolatile single-chip solutions without configuration bitstreams
• Applications requiring mixed-voltage interface compatibility with 5 V tolerance

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix indicates RoHS compliant packaging if required by environmental regulations. Ensure the TQFP-176 package dimensions match the target PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. The -1 speed grade offers approximately 15% faster performance than the standard grade. Verify that the 176-pin TQFP package provides adequate pin count for the required I/O configuration compared to BGA options.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using metal-to-metal programmable antifuse technology. The family includes devices ranging from 12,000 to 108,000 system gates, offering various package options and temperature grades to suit different commercial and industrial application needs.

Replacement Considerations

Compatible replacements within the same series include other A54SX32A variants with different speed grades or packages, such as A54SX32A-1TQ144I or A54SX32A-1BG329I. Ensure the replacement maintains the required gate count and I/O availability while matching the thermal and electrical specifications.
