A54SX16A-2TQ144I

Overview

The A54SX16A-2TQ144I is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates at a maximum system 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 144-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 insertion into active systems without damage
• Provides nonvolatile single-chip solution eliminating configuration bitstream interception risks
• Enables deterministic timing through user-controllable resource utilization and pin locking

Applications

• High-performance digital signal processing requiring fast counters and state machines
• PCI-compliant interface designs operating at 66 MHz
• Secure embedded applications utilizing FuseLock anti-tamper technology

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the design tool version supports the SX-A architecture for proper place-and-route implementation. Confirm RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when a balance of moderate gate count and high-speed performance is required. The -2 speed grade offers approximately 25% faster performance than standard grades. Consider the TQFP package for surface-mount applications where leaded footprint compatibility is necessary. Verify I/O voltage requirements match the available configurable standards.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal programmable antifuse interconnect. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX16A variant specifically provides 1,452 CLBs and up to 180 user-programmable I/O pins depending on the package selected.
