A54SX08A-FG144I

Overview

The A54SX08A-FG144I is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 typical system gates and 768 logic modules (combinatorial cells). The device supports up to 111 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 144-pin Fine Pitch Ball Grid Array package with a 1.0 mm pitch.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap capabilities and power-up/down friendly operation, allowing supply voltages to be powered in any order without sequencing requirements.
• Features deterministic timing through patented DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing for superior diagnostic and verification capabilities.

Applications

• Low-power, high-performance designs requiring nonvolatile configuration
• Systems requiring hot-swappable FPGA integration
• Industrial applications operating within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix 'FG' corresponds to the 1.0 mm Fine Pitch Ball Grid Array package and 'I' indicates the Industrial temperature grade (-40°C to +85°C) as defined in the official datasheet. Confirm RoHS compliance status if required by your manufacturing specifications. Ensure design tools support the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this component when a nonvolatile FPGA with deterministic timing is required. The SX-A architecture offers 100% pin-locking capability, which facilitates concurrent PCB development. Consider the available speed grades and I/O voltage standards (3.3 V / 5 V PCI, 5 V TTL) to ensure compatibility with system interfaces.
