A54SX08A-FFG144

Overview

The A54SX08A-FFG144 is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It features 768 logic modules and 8,000 typical system gates within a 144-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 113 user-programmable I/O pins and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It provides deterministic timing performance with internal clock frequencies reaching 350 MHz.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allow insertion into active systems without power sequencing requirements or system degradation.
• Includes Silicon Explorer II in-system diagnostic capabilities and IEEE 1149.1 (JTAG) boundary-scan testing compliance.

Applications

• Integration of CPLD and FPGA functionality into a single-chip solution for high-performance designs.
• Systems requiring hot-swappable components where power-up/down sequencing is not required.
• Applications needing secure programming to prevent reverse engineering and design theft via FuseLock technology.

Procurement Notes

Verify the specific speed grade suffix associated with the FFG144 package, as standard speed grades are typically designated by blank or -1/-2 suffixes. Confirm that the 'G' suffix indicates RoHS-compliant packaging if environmental compliance is required. Ensure the industrial temperature range ('I') is selected if operation below 0°C is necessary, as commercial grades are limited to 0°C to +70°C.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based devices to eliminate configuration boot times. The SX-A family is suitable for designs requiring deterministic timing and high pin-locking utilization. Consider the 0.22 μm/0.25 μm CMOS process technology for low-power applications compared to older generation devices.

Part Context

This part belongs to the Actel/Microsemi SX-A family of FPGAs, which utilizes antifuse technology rather than SRAM or flash. The A54SX08A variant represents the entry-level capacity in the series with 8,000 typical system gates. The FFG144 designation specifies the 144-pin Fine Pitch Ball Grid Array package type.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX08A such as A54SX08A-FG144 or A54SX08A-1FG144. For higher capacity needs in the same package, the A54SX16A-FFG144 may be considered, though resource availability will differ significantly.
