A54SX16A-TQ144A

The A54SX16A-TQ144A is an SX-A family, nonvolatile Field Programmable Gate Array (FPGA) offered in a 144-pin LQFP/TQFP package. It delivers 24,000 system gates and 1,452 logic elements with up to 113 user I/O pins, providing a compact, single‑chip programmable solution for embedded and automotive applications.

Designed for robust operation across a wide supply and temperature range, this device combines configurable I/O support, deterministic timing and on-chip security features to address control, interface and mixed-signal glue logic tasks in systems that require automotive qualification and extended temperature performance.

Key Features

• Capacity and Logic — 24,000 system gates delivered through approximately 1,452 logic elements and dedicated register resources, enabling moderate-complexity logic implementations.
• User I/O and Configurable I/O Standards — Up to 113 user I/Os with configurable support for 3.3 V PCI, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling and individual output slew-rate control.
• Nonvolatile Single‑Chip Architecture — Nonvolatile configuration preserves design state without external configuration memory and supports power-up/power-down friendly operation with no sequencing required for supply rails.
• Performance and Clocks — Internal performance up to 250 MHz (as specified for the SX-A family) and multiple on-chip clock resources for deterministic, user-controllable timing.
• I/O Robustness — Hot-swap compliant I/Os plus configurable weak pull-up or pull-down on outputs at power-up to simplify system integration.
• Security and Testability — Secure programming technology with FuseLock and IEEE 1149.1 (JTAG) boundary-scan support; in-system diagnostic and verification capability with Silicon Explorer II.
• Power and Supply — Flexible supply range from 2.25 V to 5.25 V, supporting a variety of mixed-voltage board designs.
• Package and Thermal — Surface-mount 144-LQFP package (supplier device package: 144-TQFP, 20×20) rated for operation from −40 °C to 125 °C and qualified to AEC‑Q100 for automotive applications.
• Resource Utilization — Architecture supports up to 100% resource utilization and 100% pin locking for predictable placement and timing closure.
• Memory — No embedded RAM (total RAM bits: 0), relying on logic and flip-flop resources for state and buffering.

Typical Applications

• Automotive Control Systems — Automotive-grade qualification (AEC‑Q100) and extended temperature support make the device suitable for in‑vehicle control logic and interface tasks.
• Industrial and Embedded Interfaces — Configurable I/O standards and hot-swap capable pins enable board-level interface logic, protocol bridging and mixed-voltage glue logic in embedded platforms.
• PCI‑Compliant Subsystems — PCI-compliant signaling support allows implementation of peripheral logic and PCI interface functions where 3.3 V PCI compatibility is required.
• On‑board Security and Test — FuseLock secure programming and JTAG boundary-scan facilitate secure configuration and manufacturing test/diagnostic flows.

Unique Advantages

• Automotive-Grade Qualification: AEC‑Q100 qualification and −40 °C to 125 °C operating range provide the environmental robustness required for automotive deployments.
• Nonvolatile, Single‑Chip Solution: Eliminates the need for external configuration memory and simplifies power sequencing and system BOM.
• Flexible Voltage and I/O Support: Wide supply range (2.25 V–5.25 V) plus multi-standard I/O support reduces the need for level translators and eases integration with mixed-voltage peripherals.
• Deterministic Timing and Diagnostics: User-controllable timing, boundary-scan and in-system diagnostic tools enable predictable performance and streamlined validation.
• Secure Programming: FuseLock technology helps protect intellectual property and prevents reverse engineering of programmed designs.
• Compact Package with High I/O Count: 144-pin LQFP/TQFP packaging provides a balance of pin density and PCB footprint for space-constrained designs requiring up to 113 I/Os.
