A54SX32A-1TQG176M

Overview

The A54SX32A-1TQG176M 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/Os for 2.5 V, 3.3 V, and 5 V applications. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without voltage sequencing requirements.
• Provides deterministic timing through user-controllable delays and 100% pin-locking resource utilization.
• Includes IEEE 1149.1 compliant boundary-scan testing and Actel Secure Programming Technology to prevent reverse engineering.

Applications

• Integration of CPLD and FPGA functionalities into single-chip solutions.
• Designs requiring 66 MHz PCI compliance.
• Applications needing mixed-voltage interface support for 3.3 V/5 V PCI, 5 V TTL, and 2.5 V LVCMOS2.

Procurement Notes

Verify the specific speed grade suffix '1' indicates approximately 15% faster performance than standard speed. Confirm the 'G' suffix denotes RoHS compliant packaging if required by environmental standards. Ensure the TQFP-176 package dimensions match the target PCB footprint constraints during procurement planning.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design logic density. The -1 speed grade offers higher performance than the standard version but lower than the -2 grade. Verify that the 176-pin TQFP package meets the available board space and thermal dissipation requirements for the intended operating environment.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize nonvolatile antifuse technology. The A54SX32A designation specifically identifies the device capacity within the series, distinguishing it from smaller variants like the A54SX16A or larger ones like the A54SX72A.
