A54SX16P-PQ208M

The A54SX16P-PQ208M is a military-grade, nonvolatile SX family FPGA delivered in a 208-pin PQFP package. It provides 24,000 system gates and 1,452 logic elements with up to 175 user-programmable I/Os, supporting mixed-voltage operation and mission-critical operating temperatures.

Designed for applications that require deterministic timing, secure configuration, and robust I/O flexibility, this device targets high-reliability embedded systems where wide supply and temperature ranges are required.

Key Features

• Logic Capacity — 24,000 system gates and 1,452 logic elements provide a mid-range programmable fabric for control, glue-logic, and moderate-density signal processing functions.
• User I/O — 175 user-programmable I/Os with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, and multiple LVCMOS/LVTTL levels, including 5 V input tolerance and configurable weak pull-up/pull-down at power-up.
• Voltage and Power — Wide voltage supply range from 3.0 V to 5.5 V and power-up/power-down friendly operation that requires no sequencing of supply voltages.
• Performance (SX Family) — Family-level system and internal performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance.
• Package and Mounting — 208-pin BFQFP (supplier package listed as 208-PQFP, 28 × 28 mm) in a surface-mount form factor suitable for board-level integration.
• Temperature and Grade — Military temperature grade with specified operation from –55 °C to 125 °C, suitable for high-reliability environments.
• Security and Test — Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering, plus IEEE 1149.1-compliant boundary-scan (JTAG) for test and debug.
• System Integration — Nonvolatile, single-chip FPGA architecture with deterministic, user-controllable timing and in-system diagnostics (Silicon Explorer II support noted for family devices).
• Standards Compliance — Family-level support includes 66 MHz PCI compliance and hot-swap compliant I/Os where applicable.
• Environmental — RoHS compliant.

Typical Applications

• Military and Aerospace Systems — Military-grade temperature range and surface-mount 208-pin packaging make this FPGA suitable for high-reliability control, signal-conditioning, and interface functions.
• Embedded Control and Data Acquisition — Deterministic timing and flexible I/O voltage support enable use as glue logic, protocol bridging, and I/O expansion in embedded controllers.
• PCI-Connected Designs — 66 MHz PCI compliance and mixed-voltage I/O support simplify integration into legacy and mixed-voltage PCI systems.
• Secure or IP-Protected Designs — Built-in FuseLock™ secure programming technology helps protect intellectual property and prevent reverse engineering.
• Production Test and Development — IEEE 1149.1 boundary-scan support aids board-level testability and in-system diagnostics during manufacturing and field service.

Unique Advantages

• Military-Grade Reliability: Specified for –55 °C to 125 °C operation and delivered in a rugged surface-mount PQFP package for demanding environments.
• Wide Supply Flexibility: 3.0 V to 5.5 V supply range supports mixed-voltage systems and eases integration across legacy and modern logic domains.
• Nonvolatile Single-Chip Solution: Eliminates the need for external configuration memory while enabling deterministic startup behavior.
• Secure Deployment: FuseLock™ secure programming reduces risk of IP theft and reverse engineering in fielded systems.
• Comprehensive I/O Control: Configurable pull-up/pull-down on power-up, 5 V tolerance, and individual output slew-rate control simplify interface design and signal integrity tuning.
• Testability and Diagnostics: Boundary-scan (JTAG) and family support for in-system diagnostic tools facilitate debug and reduce time-to-market.
