A54SX16A-TQ144M

The A54SX16A-TQ144M is a military‑grade SX‑A family Field Programmable Gate Array in a 144‑pin quad flat package. It provides approximately 24,000 system gates implemented across 1,452 logic elements and up to 113 user I/Os in the 144‑pin package, targeting designs that require nonvolatile configuration, predictable timing, and operational reliability across a wide temperature range.

Built for applications that need mixed‑voltage I/O support, hot‑swap capability, and in‑system diagnostic features, this single‑chip FPGA delivers family-level performance characteristics including 250 MHz system performance and 350 MHz internal performance.

Key Features

• Logic Capacity — Approximately 24,000 system gates implemented across 1,452 logic elements for moderate complexity digital designs.
• User I/O Count — 113 user‑programmable I/Os in the 144‑pin package, enabling multiple peripheral and interface connections.
• Nonvolatile Single‑Chip Architecture — Single‑chip, nonvolatile configuration removes the need for external configuration memory and supports instant-on behavior.
• Performance — Family specifications list 250 MHz system performance and up to 350 MHz internal performance for timing‑sensitive functions.
• Mixed‑Voltage I/O and 5 V Tolerance — Configurable I/O supports 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance and 5 V drive strength as specified by the SX‑A family features.
• Wide Supply Range — Voltage supply range from 2.25 V to 5.25 V to accommodate diverse system power rails.
• Military Temperature Grade — Operating temperature range −55 °C to 125 °C and specified as Military grade for harsh environments.
• Package and Mounting — 144‑pin LQFP package (supplier package listed as 144‑TQFP 20×20); surface‑mount mounting type.
• System Reliability and Test — Boundary‑scan testing compliant with IEEE 1149.1 (JTAG) and in‑system diagnostic/verification capability as provided in the SX‑A family.
• Security — Family feature: Actel Secure Programming Technology with FuseLock to protect design IP against reverse engineering.
• Power‑Up/Down Friendly — I/Os specified as power‑up/down friendly with no sequencing required for supply voltages in family documentation.
• On‑Chip Memory — Total on‑chip RAM bits: 0, for designs that rely on external memory or register resources.
• RoHS Compliant — Device is RoHS compliant for environmental conformity.

Typical Applications

• PCI Interface Logic — Family‑level PCI compliance and configurable I/O enable implementation of PCI‑related glue logic and interface bridging in systems that require 3.3 V/5 V support.
• Mil‑Grade Control Systems — Military temperature grading (−55 °C to 125 °C) and surface‑mount packaging make the device suitable for deployed defense and avionics electronic control functions.
• In‑System Diagnostics and Verification — Built‑in boundary‑scan and in‑system diagnostic capabilities support board‑level test, field verification, and fault isolation workflows.
• Mixed‑Voltage Interface Bridging — Configurable I/O and wide supply range support mixed‑voltage system interfacing without extensive level‑shifting hardware.

Unique Advantages

• Nonvolatile, single‑chip solution: Eliminates external configuration memory to simplify board layout and reduce BOM count.
• Deterministic timing and high utilization: Family support for deterministic, user‑controllable timing and up to 100% resource utilization helps simplify timing closure and maximize device use.
• Security features: FuseLock secure programming technology protects IP and helps preserve design confidentiality.
• Robust I/O and power handling: Hot‑swap compliant I/Os and power‑up/down friendly behavior reduce system complexity during power sequencing and board hot‑swap events.
• Wide operating conditions: Broad supply range (2.25 V–5.25 V) and military temperature rating support operation across diverse system environments.
• Testability and diagnostics: IEEE 1149.1 boundary‑scan and in‑system diagnostic capabilities speed validation, bring‑up, and field maintenance.
