A54SX16A-TQG144M

The A54SX16A-TQG144M is a member of the SX‑A family of nonvolatile FPGAs. It provides a single‑chip, nonvolatile programmable logic solution with 24,000 system gates and approximately 1,452 logic elements, packaged in a 144‑pin thin quad flat pack (TQFP) surface‑mount package.

Designed for applications that require mixed‑voltage I/O, deterministic timing and military operating temperatures, this device targets secure and high‑reliability embedded systems, board‑level logic integration, and interface or protocol bridging where a compact, nonvolatile FPGA is required.

Key Features

• Core performance — Rated for up to 250 MHz system performance and up to 350 MHz internal performance as part of the SX‑A family.
• Logic capacity — Approximately 24,000 system gates and 1,452 logic elements (cells) to implement glue logic, control state machines and protocol handlers.
• User I/O — 113 user‑programmable I/Os available in the 144‑pin TQFP package for board‑level interfacing.
• Mixed‑voltage I/O 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.
• Power and reliability — Power‑up/power‑down friendly operation with no supply sequencing required; voltage supply range 2.25 V to 5.25 V.
• Security and nonvolatility — Nonvolatile, single‑chip solution with Actel Secure Programming Technology (FuseLock™) to help protect designs from reverse engineering.
• I/O control and signal integrity — Configurable weak resistor pull‑up/pull‑down at power‑up and individual output slew rate control to help manage signal integrity.
• Test and debug — Boundary‑scan testing compliant with IEEE 1149.1 (JTAG) and in‑system diagnostic/verification capability (Silicon Explorer II support).
• Package and environmental — 144‑pin TQFP (20 × 20 mm) surface‑mount package; RoHS compliant and specified for military temperature range (‑55 °C to +125 °C).
• On‑chip memory — No embedded RAM (Total RAM Bits: 0), suitable for designs that use external memory or require RAM‑less deterministic logic.

Typical Applications

• Military & aerospace systems — Rugged, temperature‑tolerant programmable logic for mission‑critical control, signal conditioning and interface tasks.
• Mixed‑voltage interface and legacy bus bridging — Implement level‑translation, protocol bridging and 66 MHz PCI‑compatible interfaces using configurable mixed‑voltage I/O.
• Secure embedded systems — In‑system programmability combined with FuseLock security helps protect sensitive IP and prevent reverse engineering.
• Deterministic control and timing — Timing‑sensitive finite state machines, sequencers and interface controllers that benefit from deterministic, user‑controllable timing.

Unique Advantages

• Military temperature rating: Specified for −55 °C to +125 °C operation, enabling deployment in harsh environments.
• Nonvolatile single‑chip solution: Eliminates the need for external configuration memory and simplifies system power‑up behavior.
• Flexible mixed‑voltage I/O: Simplifies interfacing with 2.5 V, 3.3 V and 5 V logic without extensive level‑shifting hardware.
• Built‑in security: FuseLock™ secure programming technology helps protect design IP and deter reverse engineering.
• Deterministic high‑speed operation: System and internal performance ratings support timing‑sensitive designs up to the listed core speeds.
• Compact surface‑mount package: 144‑pin TQFP (20×20 mm) provides a low‑profile, board‑level solution for space‑constrained designs.
