A54SX16A-2TQ144I

The A54SX16A-2TQ144I is an SX-A family, nonvolatile single-chip FPGA offered by Microchip Technology. It delivers 24,000 system gates and approximately 1,452 logic elements with 113 user I/Os in a 144-pin LQFP/TQFP package, targeted at designs that require configurable mixed-voltage I/O and deterministic timing control.

Built for mixed-voltage systems and industrial-temperature operation, the device supports flexible I/O configurations and a broad supply range, making it suitable for interface bridging, control logic, and in-system programmable applications that benefit from secure programming and boundary-scan testing.

Key Features

• Logic Capacity — 24,000 system gates and approximately 1,452 logic elements provide a compact programmable fabric for glue logic, protocol bridging, and control functions.
• User I/O — 113 user I/Os available in the 144-pin package enable a wide range of external interfaces and signal routing options.
• Family Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance.
• Configurable Mixed-Voltage I/O — I/O supports multiple standards and mixed-voltage operation (2.5 V, 3.3 V, and 5 V) with 5 V input tolerance and configurable weak pull-up/pull-down at power-up.
• Power and Supply — Wide supply voltage support from 2.25 V to 5.25 V and power-up/power-down friendly behavior (no sequencing required for supply voltages).
• Packaging & Mounting — Surface-mount 144-pin package (listed as 144-LQFP / supplier 144-TQFP 20×20) for compact board designs.
• Industrial Temperature Grade — Rated for operation from –40 °C to 85 °C.
• System Integration & Test — Boundary-scan testing (IEEE 1149.1 JTAG) and in-system diagnostic/verification capability as part of the SX-A family feature set.
• Security — Family-level secure programming technology (FuseLock) to help protect intellectual property and prevent reverse engineering.
• Compliance — RoHS compliant and designed with hot-swap–capable I/Os for robust deployment scenarios.

Typical Applications

• PCI and legacy bus bridging — 66 MHz PCI compliance and 5 V-tolerant I/O make the device suitable for interfacing between PCI and other bus standards.
• Industrial control and I/O management — Industrial temperature rating, hot-swap–capable I/Os, and configurable pull-ups/pull-downs support reliable I/O handling in control systems.
• Secure programmable logic — FuseLock secure programming and in-system verification enable designs that require IP protection and field updates.
• Interface glue logic and protocol conversion — Mixed-voltage I/O and deterministic timing support use as a compact, integrated glue-logic FPGA for embedded systems.

Unique Advantages

• Deterministic, user-controllable timing: Family features provide timing control useful for repeatable system behavior and predictable interfacing.
• Flexible mixed-voltage support: 2.5 V, 3.3 V, and 5 V operation with 5 V input tolerance reduces the need for external level-shifting components.
• Nonvolatile single-chip solution: Eliminates the requirement for external configuration memory, simplifying board design and boot behavior.
• Industrial-grade operation: –40 °C to 85 °C rating and surface-mount 144-pin package for deployment in temperature-sensitive applications.
• Security and testability: FuseLock secure programming plus IEEE 1149.1 boundary-scan support for IP protection and production test.
• Compact I/O count with strong integration: 113 user I/Os and up to ~1,452 logic elements deliver a balance of interface density and programmable logic in a small footprint.
