A54SX08A-FTQG144

The A54SX08A-FTQG144 is an SX-A family field programmable gate array supplied by Microchip Technology. This nonvolatile, single‑chip FPGA provides approximately 12,000 system gates, 768 logic elements, and 113 user‑programmable I/O pins in a 144‑pin thin quad flat pack (144‑LQFP) surface‑mount package. It targets designs that require mixed‑voltage I/O support, hot‑swap capable interfaces, and deterministic, in‑system programmability.

With a supply voltage range of 2.25 V to 5.25 V and an operating temperature range of 0 °C to 70 °C, the device is suitable for commercial‑grade embedded designs where compact FPGA logic, flexible I/O, and nonvolatile configuration are required.

Key Features

• Logic Capacity — Approximately 12,000 system gates implemented across 768 logic elements, enabling moderate-density programmable logic integration.
• I/O and Clocking — 113 user I/O pins with configurable I/O standards and support for up to 3 global clocks for system timing.
• Performance — Family specifications list up to 250 MHz system performance and up to 350 MHz internal performance for timing‑critical paths.
• Nonvolatile Single‑Chip Architecture — Device retains configuration without external memory, simplifying system design and reducing component count.
• Mixed‑Voltage and PCI Support — Configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; supports mixed 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance and 5 V drive strength.
• Hot‑Swap and Power‑Up Friendly I/Os — I/Os are hot‑swap compliant and do not require supply sequencing during power up or down.
• System Reliability and Security — Boundary‑scan testing (IEEE 1149.1 compliant) and Actel Secure Programming Technology (FuseLock) for protection against reverse engineering and unauthorized readback.
• Programmability and Diagnostics — Deterministic, user‑controllable timing and in‑system diagnostic/verification capability (Silicon Explorer II referenced in family documentation).
• Package and Mounting — Surface mount 144‑pin LQFP package (supplier refers to 144‑TQFP 20×20 variant), RoHS compliant.
• On‑Chip Memory — No embedded RAM (total RAM bits: 0), suitable for designs relying on distributed logic or external memory resources.

Typical Applications

• PCI and Peripheral Interfaces — Implement PCI‑compliant interfaces or peripheral bridging using the device’s 66 MHz PCI compatibility and configurable 3.3 V/5 V I/O support.
• Mixed‑Voltage Logic Bridging — Integrate logic between subsystems operating at 2.5 V, 3.3 V, and 5 V while retaining 5 V input tolerance and drive capability.
• Hot‑Swap Capable Modules — Use in hot‑swap designs where I/Os must tolerate live insertion and removal without supply sequencing.
• Compact, Nonvolatile FPGA Solutions — Replace glue logic and discrete components with a single nonvolatile FPGA to reduce board area and BOM count.

Unique Advantages

• Nonvolatile Configuration: Single‑chip nonvolatile architecture eliminates external configuration memory and simplifies system initialization.
• Flexible Mixed‑Voltage I/O: Wide I/O standard support and 5 V tolerant inputs allow direct interfacing across legacy and modern voltage domains.
• Hot‑Swap Ready: I/Os designed for hot‑swap operation reduce system downtime and simplify replacement or maintenance procedures.
• Security and Testability: Built‑in boundary‑scan support and FuseLock programming technology help protect intellectual property and streamline manufacturing test.
• Compact Package: 144‑pin surface‑mount package supports dense board layouts while providing 113 user I/Os for versatile interfacing.
