A54SX16A-TQG100A

The A54SX16A-TQG100A is an SX-A family field programmable gate array supplied in a 100-pin thin quad flat pack / low-profile quad flat pack package. It provides 24,000 system gates implemented as approximately 1,452 logic elements with 81 user I/Os and nonvolatile single-chip configuration.

Designed for applications requiring configurable digital logic with automotive-grade qualification, the device delivers flexible I/O levels, hot-swap I/O behavior, and extended operating range to support designs that must operate from 2.25 V to 5.25 V and across −40 °C to 125 °C.

Key Features

• Logic Capacity  Approximately 1,452 logic elements delivering about 24,000 system gates for medium-density FPGA implementations.
• User I/O  81 programmable I/O pins with configurable I/O support for 3.3V PCI, 3.3V LVTTL and 2.5V LVCMOS2 voltage standards and individual output slew-rate control.
• Nonvolatile Single-Chip Solution  Built-in nonvolatile configuration (single-chip FPGA) removes the need for external configuration memory and supports power-up/down friendly behavior with no sequencing required for supply voltages.
• Automotive Qualification & Temperature  Automotive grade with AEC-Q100 qualification and an operating temperature range of −40 °C to 125 °C for demanding environments.
• Power & Supply  Broad supply range from 2.25 V to 5.25 V to accommodate mixed-voltage systems and simplify interfacing.
• Performance & Interfaces  Family-level performance notes include internal operation up to 250 MHz and 66 MHz PCI compliance; supports hot-swap compliant I/Os and configurable weak pull-up/pull-down on outputs at power-up.
• System-Level Test & Security  Boundary-scan testing (IEEE 1149.1 / JTAG) and secure programming technology (FuseLock™) for protection against reverse engineering and design theft.
• Package & Mounting  Surface-mount 100-pin package offered as 100-LQFP / 100-TQFP (14×14) to fit compact PCB footprints.
• Compliance  RoHS-compliant manufacturing.

Typical Applications

• Automotive Body Electronics  Use as a configurable glue-logic and interface controller in body control modules where AEC-Q100 qualification and extended temperature operation are required.
• In-vehicle Interfaces and Bridging  Implement protocol bridging, PCI/legacy interface support and custom I/O translation using configurable voltage standards and hot-swap-capable I/Os.
• Instrument and Control Systems  Medium-density programmable logic for control, signal conditioning, and deterministic timing in systems that require nonvolatile configuration and robust thermal performance.

Unique Advantages

• Automotive-Grade Reliability: AEC-Q100 qualification plus −40 °C to 125 °C operating range supports deployment in temperature-extreme automotive environments.
• Reduced BOM and Footprint: Nonvolatile single-chip configuration eliminates external configuration memory and simplifies board-level design.
• Flexible Mixed-Voltage I/O: Configurable I/O standards and wide supply range enable direct interfacing with multiple voltage domains without external translators.
• Built-in Test and Security: Boundary-scan (JTAG) support and secure programming (FuseLock) help validate designs and protect intellectual property.
• Predictable Integration: Deterministic timing and configurable output features allow consistent implementation across production units.
• Compact Surface-Mount Package: Available in 100-pin TQFP/LQFP packages for space-constrained PCB layouts.
