A54SX08A-2FG144I

Overview

The A54SX08A-2FG144I is a Field Programmable Gate Array from the Microsemi SX-A family, featuring 768 logic modules and 12,000 system gates. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The device supports up to 111 user-programmable I/O pins and includes 512 dedicated flip-flops. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and functions within a voltage range of 2.25 V to 5.25 V. The component is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities and power-up/down operations without requiring specific sequencing for supply voltages.
• Features deterministic timing through Actel's patented metal-to-metal programmable antifuse interconnect elements.
• Includes IEEE 1149.1 compliant boundary-scan testing and Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• Integration of CPLD and FPGA functionalities into single-chip solutions.
• Designs requiring 66 MHz PCI compliance.
• Mixed-voltage systems supporting 2.5 V, 3.3 V, and 5 V operation.

Procurement Notes

Verify the part number against official Microsemi documentation to confirm the specific speed grade and temperature rating. Ensure that the FBGA package dimensions and pinout match the design requirements. Check for RoHS compliance status if required by local regulations. Confirm availability as older series components may have limited stock or end-of-life status.

Selection Notes

Select this model when 12,000 system gates are sufficient for the logic density requirements. The -2 speed grade offers approximately 25% faster performance than the standard grade. Choose the FG package for fine-pitch board applications. Verify that the industrial temperature range meets the environmental constraints of the target deployment scenario.

Part Context

This component belongs to the SX-A family of FPGAs, which are fabricated using antifuse technology. The family includes devices with varying capacities, such as the A54SX16A and A54SX32A. The A54SX08A variant represents the entry-level capacity within this specific high-performance generation, offering a balance of gate count and pin availability for compact designs.

Replacement Considerations

Compatible alternatives within the same family include the A54SX08A-1FG144I for standard speed or the A54SX08A-FG144I for slower performance. For higher capacity needs, consider the A54SX16A-2FG144I. Ensure that any replacement maintains the FBGA-144 package footprint and compatible voltage specifications.
