A54SX16A-PQG208A

The A54SX16A-PQG208A is an SX-A family FPGA in a 208-pin plastic quad flat pack package targeted for automotive applications. It provides a nonvolatile, single-chip programmable logic solution with 24,000 system gates and 1,452 logic elements for logic integration where temperature range, I/O flexibility and in-system diagnostics are required.

Designed and qualified to AEC-Q100, the device supports an extended operating range from –40°C to 125°C and a wide supply range of 2.25 V to 5.25 V, making it suitable for demanding vehicle environments and other temperature-challenged systems.

Key Features

• Core Capacity — 24,000 system gates and approximately 1,452 logic elements (combinatorial cells) provide programmable logic density for mid-range integration needs.
• Logic Resources — Dedicated flip-flops available per device family description; the architecture supports deterministic, user-controllable timing for predictable system behavior.
• I/O and Interface Flexibility — 175 user I/O pins with configurable I/O support for 3.3 V PCI, 3.3 V LVTTL and 2.5 V LVCMOS2 levels and individual output slew rate control.
• Automotive Qualification — Grade: Automotive with AEC-Q100 qualification and an operating temperature range of –40°C to 125°C.
• Power and Supply Handling — Wide operating supply range from 2.25 V to 5.25 V and power-up/power-down friendly behavior that requires no sequencing of supply voltages.
• Performance — Internal performance capability specified up to 250 MHz and 66 MHz PCI compliance for bus applications.
• Reliability and Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability with Silicon Explorer II.
• Security and Nonvolatile Configuration — Nonvolatile single-chip solution with Secure Programming Technology (FuseLock™) to help protect design IP.
• Packaging — 208-pin BFQFP package (supplier device package listed as 208-PQFP, 28×28 mm reference).
• Embedded Memory — Total on-chip RAM bits: 0 (no embedded RAM).

Typical Applications

• Automotive control and interface modules — Automotive-grade qualification (AEC-Q100) and extended temperature support enable use in vehicle electronics that require programmable logic and robust I/O.
• PCI and bus-interfacing devices — 66 MHz PCI compliance and configurable 3.3 V PCI I/O support make the device suitable for PCI-compliant bridging or interface functions.
• Systems needing nonvolatile programmable logic — The single-chip nonvolatile architecture is appropriate for designs that benefit from retained configuration without external configuration memory.

Unique Advantages

• Automotive-rated platform: AEC-Q100 qualification combined with –40°C to 125°C operation supports deployment in automotive environments that demand extended temperature performance.
• Single-chip, nonvolatile solution: Eliminates the need for external configuration memory, simplifying BOM and startup behavior.
• Flexible I/O support: Configurable I/O voltage levels and per-output slew control enable interfacing with a variety of legacy and modern logic families and bus standards.
• Deterministic timing and diagnostics: User-controllable timing and in-system diagnostic capabilities aid integration, verification and long-term maintainability.
• Security features: Secure Programming Technology (FuseLock™) helps protect design intellectual property and prevent reverse engineering.
• Power sequencing tolerance: Power-up/down friendly behavior reduces system-level constraints and simplifies power rail design.
