A54SX16A-2FG256

Overview

The A54SX16A-2FG256 is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration. The device supports up to 180 user-programmable I/O pins within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. It operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. Electrical specifications include a supply voltage range of 2.25 V to 2.75 V for core operation, supporting mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without damage
• Features deterministic timing with 100% resource utilization and pin locking capabilities
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)
• Provides secure programming technology to prevent reverse engineering

Applications

• High-performance digital signal processing
• Complex state machine implementations
• PCI bus interface designs
• Prototyping for ASIC functionality

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm RoHS compliance status based on specific ordering suffixes if required by regulatory standards. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the specific speed grade matches design requirements before finalizing procurement orders.

Selection Notes

Select this model when 24,000 system gates and 180 I/Os are sufficient for the target application. The -2 speed grade offers approximately 25% faster performance than standard grades. Ensure the FBGA256 package fits the PCB layout constraints. Verify thermal management requirements for the commercial temperature grade operating range.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which transitioned to Microchip Technology following acquisition. The SX-A series is characterized by its metal-to-metal antifuse interconnect architecture, providing permanent low-impedance connections. This family bridges the gap between CPLDs and larger FPGAs, offering high density in a single-chip solution.

Replacement Considerations

Check for updated Microchip part numbers as Actel product lines have been integrated. Verify pin compatibility and electrical characteristics against newer FPGA families if upgrading. Consider availability of equivalent gate counts in current Microchip portfolios.
