A54SX32-2BGG329I

Overview

The A54SX32-2BGG329I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 configurable logic blocks. It supports up to 249 user-programmable I/O pins and operates with internal clock frequencies up to 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5.0 V with 5.0 V input tolerance. It is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and is rated for industrial temperature ranges of -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without supply voltage sequencing requirements.
• Provides deterministic, user-controllable timing with 100% resource utilization and pin locking.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Features boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• 66 MHz PCI compliant single-chip solutions
• Low-power, high-performance designs requiring nonvolatile integration
• Systems requiring mixed-voltage I/O support for 3.3 V/5 V PCI, 5 V TTL, and 3.3 V LVTTL

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as packaging options may vary between standard and lead-free versions. Check for product discontinuation notifications or end-of-life status prior to finalizing procurement plans.

Selection Notes

Select this component when designing systems that require nonvolatile FPGA architecture with high-speed performance up to 350 MHz internal clocking. Ensure the design accommodates the 329-pin PBGA footprint and meets the thermal requirements for the industrial grade (-40°C to +85°C). Verify that the 249 available I/O pins satisfy the interface count and that mixed-voltage levels match the target application standards.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using metal-to-metal programmable antifuse technology. The SX-A series is designed to replace multiple CPLDs and gate arrays in a single chip, offering low power consumption and high density. The A54SX32 variant specifically provides 48,000 system gates, positioning it within the mid-range capacity of the family.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as A54SX32A-1BGG329I or A54SX32A-FBGG329I, provided the timing requirements are met. Cross-family migration to newer Microchip FPGA architectures requires schematic and code re-verification due to architectural differences.
