A54SX16A-2TQ144

The A54SX16A-2TQ144 is a commercial-grade SX-A family FPGA in a 144-pin thin quad flat pack package, offering a moderate logic density and flexible mixed-voltage I/O. It delivers a nonvolatile, single-chip programmable solution tailored for system-level logic integration, I/O bridging and PCI‑compliant designs.

Designed for applications that require deterministic timing, in-system diagnostics and configurable I/O, this device combines approximately 24,000 system gates with 1,452 logic elements and up to 113 user I/Os in the 144‑pin package.

Key Features

• Core Performance — Series-specified performance includes 250 MHz system performance and 350 MHz internal performance for responsive logic operation.
• Logic Capacity — Approximately 24,000 system gates with 1,452 logic elements, supporting mid-range FPGA designs and glue logic implementations.
• I/O and Interface Flexibility — 113 user-programmable I/Os in the 144-pin package; configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, enabling mixed-voltage interfacing and 5 V input tolerance.
• Voltage and Power — Wide supply range from 2.25 V to 5.25 V and power-up/power-down friendly operation with no supply sequencing required; hot-swap compliant I/Os simplify board-level power management.
• On-chip Memory — No embedded RAM (Total RAM Bits: 0), making the part suitable where LUT-based logic and flip-flop resources are the primary requirements.
• Package and Mounting — 144‑LQFP / 144‑TQFP (20×20) surface-mount package; compact footprint for space-constrained PCBs.
• Temperature and Grade — Commercial grade with an operating temperature range of 0 °C to 70 °C.
• System Reliability and Security — Nonvolatile single-chip configuration, boundary-scan (JTAG) support, Actel Secure Programming Technology with FuseLock™ to protect programming and design IP, and unique in-system diagnostic capability with Silicon Explorer II.
• Compliance — RoHS compliant packaging.

Typical Applications

• PCI and legacy bus interfaces — Use the device’s 66 MHz PCI compliance and configurable I/O to implement PCI bridge, interface or peripheral logic.
• Glue Logic and I/O Bridging — Mixed-voltage I/O and 113 available pins in the TQ144 package enable level translation, bus interfacing and board-level glue functions.
• Embedded Control and Peripheral Management — Approximately 1,452 logic elements and dedicated flip-flops support control state machines, peripheral controllers and deterministic timing functions.
• Production Test and In-System Diagnostics — Boundary-scan (IEEE 1149.1) and Silicon Explorer II capabilities simplify manufacturing test, verification and field diagnostics.

Unique Advantages

• Nonvolatile Single‑Chip Configuration: Eliminates the need for external configuration memory, simplifying board design and startup behavior.
• Mixed‑Voltage I/O with 5 V Tolerance: Supports a variety of legacy and modern interface standards without additional level‑shifting components.
• Power‑Up/Down Friendly I/Os: No supply sequencing required and hot-swap compliant I/Os reduce system-level power management complexity.
• Integrated Security and Diagnostics: FuseLock™ programming protection and Silicon Explorer II in-system diagnostics help secure IP and accelerate debug and verification.
• Compact Surface-Mount Package: 144‑pin TQFP/LQFP format offers a balance of I/O count and PCB area for medium-density applications.
