A54SX08A-1TQ144I

The A54SX08A-1TQ144I is a member of the SX-A family of nonvolatile, single‑chip FPGAs. It provides approximately 12,000 system gates implemented as 768 logic elements with 113 user I/O pins in a 144‑pin LQFP/TQFP package, targeting embedded designs that require deterministic timing and configurable I/O.

Designed for industrial‑grade environments, the device supports mixed‑voltage operation and power‑up/power‑down friendly behavior, enabling flexible integration into control, instrumentation, and interface applications.

Key Features

• Core Performance — Family-level performance includes up to 250 MHz system performance and up to 350 MHz internal performance for timing-sensitive logic.
• Logic Capacity — Approximately 12,000 system gates implemented as 768 logic elements for mid-density logic integration.
• I/O Flexibility — 113 user I/Os (144‑pin package) with configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; supports 5 V input tolerance and 5 V drive strength at the family level.
• Power and Voltage — Wide supply range from 2.25 V to 5.25 V with power‑up/power‑down friendly operation (no sequencing required) and hot‑swap compliant I/Os.
• Security & Test — Family features include Actel Secure Programming Technology with FuseLock™ to protect intellectual property, and IEEE 1149.1 JTAG boundary‑scan for board-level testability.
• Package & Temperature — Surface‑mount 144‑pin LQFP (supplier 144‑TQFP 20×20) package; industrial temperature grade with an operating range of −40 °C to +85 °C.
• Deterministic Timing & Diagnostics — Series-level deterministic, user‑controllable timing plus in‑system diagnostic and verification capability (Silicon Explorer II) to aid development and troubleshooting.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Deterministic timing and industrial temperature operation make the device suitable for motor control logic, PLC interfaces, and factory automation subsystems.
• PCI Interface Logic — Family support for 66 MHz PCI and configurable 3.3 V/5 V PCI I/O makes the device applicable for custom PCI glue logic and bridge functions.
• Embedded Interface & Glue Logic — With 113 user I/Os and flexible voltage support, use the FPGA for protocol bridging, bus arbitration, and complex I/O conditioning in embedded systems.
• Instrumentation & Test — In‑system diagnostic/verification capability and JTAG boundary‑scan enable board bring‑up, test access, and on‑device verification in measurement and test equipment.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Eliminates external configuration memory for simplified board design and deterministic start-up behavior.
• Flexible I/O Voltage Support: Mixed‑voltage operation (2.5 V, 3.3 V, 5 V family support) and 5 V input tolerance allow direct interfacing to a wide range of legacy and modern logic levels.
• Industrial Temperature Rating: Rated for −40 °C to +85 °C, supporting deployment in industrial environments without additional qualification claims beyond the provided grade.
• Security and Testability: FuseLock™ secure programming plus IEEE 1149.1 JTAG boundary‑scan reduce risk of reverse engineering and simplify manufacturing test strategies.
• Compact Mid‑Density Integration: ~12,000 system gates and 768 logic elements provide a balance of integration density for glue logic, control tasks, and mid‑complexity FPGA functions.
• Power‑Sequencing Tolerance: Power‑up/power‑down friendly I/Os and hot‑swap compliant operation simplify multi‑rail designs and board-level power sequencing.
