A54SX16A-2TQG144I

Overview

The A54SX16A-2TQG144I is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 configurable logic blocks. 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 with a lead pitch of 1.40 mm. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without damage
• Provides deterministic timing through user-controllable routing resources like DirectConnect and FastConnect
• Includes nonvolatile single-chip architecture with FuseLock security to prevent reverse engineering
• Enables flexible power-up/down sequences without requiring specific voltage sequencing

Applications

• High-performance digital signal processing implementations
• PCI-compliant interface controllers operating at 66 MHz
• Complex state machine designs requiring fast counters
• Secure embedded logic integration with anti-tamper requirements

Procurement Notes

Verify the ordering suffix 'I' confirms the industrial temperature range specification. Confirm the '2' speed grade matches the required 250 MHz system performance target. Ensure the TQG144 package designation aligns with the PCB footprint requirements for the 144-pin thin quad flat pack. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when 24,000 system gates are sufficient for the design complexity. The -2 speed grade offers approximately 25% faster performance than standard grades. Consider the 144-pin TQFP package constraints regarding pin count versus available I/O resources. Verify that the antifuse programming infrastructure is compatible with the chosen development tools.

Part Context

This component belongs to the Actel SX-A FPGA family, which was later acquired by Microchip Technology. The SX-A series is characterized by its metal-to-metal antifuse interconnect technology, providing permanent configuration without volatile memory. This specific part represents a mid-range capacity device within the family, balancing gate density with high-speed performance capabilities.
