A54SX08A-2PQ208

Overview

The A54SX08A-2PQ208 is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, utilizing 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and 768 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 130 user-programmable I/O pins and features three global clock networks. It operates at a standard speed grade with an internal performance of 350 MHz and a system performance of 250 MHz. The component supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os and includes hot-swap compliant inputs.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements
• Configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 standards
• Deterministic timing with 100% resource utilization and pin-locking capabilities

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces including 66 MHz PCI compliance
• DSP and co-processor functions
• Applications requiring deterministic timing and high reliability

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging type. The 'I' suffix indicates industrial temperature range availability, while blank indicates commercial. Confirm lead-free status if RoHS compliance is required. Check current product lifecycle status as this series may be discontinued or transferred.

Selection Notes

Select this model when 12,000 system gates are sufficient for the design logic. The -2 speed grade offers approximately 25% faster performance than the standard grade. Ensure the 208-pin PQFP package fits the PCB layout constraints. Verify that the 2.5V to 5.25V operating voltage range matches the system power supplies.

Part Context

This part belongs to the Actel/Microsemi SX-A FPGA family, which utilizes antifuse technology for permanent configuration. The A54SX08A variant represents the entry-level capacity in the 208-pin package lineup, offering 768 logic modules. It shares architectural features like DirectConnect and FastConnect routing with larger devices in the same family.
