A54SX08-1FG144

Overview

The A54SX08-1FG144 is a Field Programmable Gate Array from the SX-A family, featuring 12,000 system gates and 768 logic modules. It operates within a voltage range of 2.25 V to 5.25 V and supports mixed-voltage I/O standards including 3.3 V, 5 V PCI, and 5 V TTL. The device provides up to 111 user-programmable I/Os in its 144-pin Fine Pitch Ball Grid Array package. It achieves a maximum system performance frequency of 250 MHz with an internal clock capability of 350 MHz. The component utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration.

Feature Summary

• Supports hot-swap operations and power-up/down without supply sequencing requirements
• Enables 100% resource utilization and 100% pin locking through deterministic timing architecture
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)

Applications

• 66 MHz PCI compliant designs
• Mixed-voltage interface integration
• High-performance state machines

Procurement Notes

Verify the specific speed grade suffix '1' against current manufacturer documentation, as datasheets indicate that higher speed grades like '-3' have been discontinued. Confirm the temperature grade suffix, as blank indicates commercial range while 'I' denotes industrial range. Ensure the ordering code matches the exact package type and pin count required for the target PCB footprint.

Selection Notes

Select this model when a single-chip nonvolatile FPGA solution with mixed 3.3 V and 5 V I/O tolerance is required. The device is suitable for applications needing deterministic timing and high-speed logic processing up to 250 MHz. Consider the 144-pin FBGA package constraints and verify that the 111 available user I/Os meet the interface requirements of the system design.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The family includes devices ranging from 8,000 to 108,000 system gates. The A54SX08 variant specifically offers 12,000 system gates and 768 configurable logic blocks, positioning it as a mid-range solution for complex logic integration compared to smaller CPLDs or larger gate arrays.
