A54SX16A-2TQ144

Overview

The A54SX16A-2TQ144 is a Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and 1,452 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates with a maximum system performance of 250 MHz and internal clock frequencies up to 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V.

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 unique metal-to-metal programmable antifuse interconnect
• Includes IEEE 1149.1 (JTAG) boundary-scan testing for diagnostic and verification capabilities

Applications

• High-performance digital signal processing requiring fast counters and state machines
• PCI-compliant interfaces operating at 66 MHz
• Secure embedded designs utilizing FuseLock technology to prevent reverse engineering
• Mixed-voltage system integration supporting 3.3 V/5 V PCI, 5 V TTL, and 2.5 V LVCMOS2 standards

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm manufacturing date codes and lot numbers against current supply chain records. Ensure storage conditions comply with moisture sensitivity level requirements prior to reflow soldering. Check for any product discontinuance notifications or end-of-life status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this model when 24,000 system gates and 113 I/Os are required in a TQFP-144 package. The -2 speed grade offers approximately 25% faster performance than standard speed grades. Verify temperature range compatibility, as blank suffix indicates commercial grade (0 to +70°C). Consider pin-locking capabilities and resource utilization limits during initial design mapping to ensure optimal placement and routing efficiency.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using high-voltage twin-well CMOS process technology. The SX-A series provides a cost-effective alternative to complex programmable logic devices and gate arrays. The A54SX16A variant specifically targets applications needing moderate logic density with high-speed performance characteristics enabled by the patented antifuse architecture.

Replacement Considerations

Publicly confirmed substitute part numbers include A54SX16A-1TQ144 for slower speed requirements and A54SX16A-TQ144 for standard speed grades. Package variations such as FBGA-144 (A54SX16A-FG144) are available for different board space constraints. All -3 speed grades have been discontinued.
