A54SX08-TQ144I

Overview

The A54SX08-TQ144I is a Field Programmable Gate Array from the Microsemi SX-A family, featuring 12,000 system gates and 768 logic modules. It utilizes antifuse technology for nonvolatile configuration and supports mixed-voltage I/O standards including 3.3V and 5V PCI, TTL, LVTTL, and LVCMOS2. The device operates within an industrial temperature range of -40°C to +85°C and is housed in a 144-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 with user-controllable output slew rates and configurable weak pull-up or pull-down resistors at power-up.
• Includes boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• Integration of 66 MHz PCI compliant designs into single-chip solutions.
• High-performance logic applications requiring deterministic timing and fast counters.
• Systems requiring secure programming to prevent reverse engineering via FuseLock technology.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the 'TQ' designation corresponds to the 144-pin Thin Quad Flat Pack package. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture.

Selection Notes

Select this model for designs requiring approximately 12,000 system gates and up to 113 user-programmable I/Os. Consider the standard speed grade unless faster performance is required. Verify that the TQFP package fits the PCB footprint constraints and thermal management requirements for the target application environment.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers high-density logic resources with low power consumption, designed to replace multiple CPLDs or gate arrays in complex digital systems.
