A54SX16A-2TQG144

The A54SX16A-2TQG144 is a commercial-grade SX‑A family FPGA from Microchip Technology that provides 24,000 system gates and 1,452 logic elements in a 144-pin thin quad flat pack (TQFP/LQFP) package. It is a nonvolatile, single-chip FPGA designed for designs that require deterministic timing, configurable I/O, and compact package options.

This device offers up to 113 user-programmable I/Os, a wide supply voltage window (2.25 V to 5.25 V), and a commercial operating temperature range of 0 °C to 70 °C, making it suitable for a range of commercial embedded and mixed-voltage applications.

Key Features

• Logic Capacity — 24,000 system gates with 1,452 logic elements, providing a mid-range programmable fabric for combinatorial and sequential logic.
• User I/O — 113 user I/Os to support peripheral interfacing and system glue logic within a compact package.
• Package Options — 144-pin LQFP package case; supplier device package listed as 144‑TQFP (20×20), enabling board-level density and standard SMT assembly.
• Supply Voltage Range — Operates from 2.25 V to 5.25 V to support mixed-voltage I/O schemes and legacy interfaces.
• Commercial Temperature Grade — Rated for 0 °C to 70 °C operation for commercial applications.
• Nonvolatile, Single-Chip Solution — Built as a nonvolatile FPGA to retain configuration without external memory and to simplify power-up sequencing.
• System and Design Support — SX‑A family features such as deterministic timing control, boundary-scan (JTAG) testing, and in-system diagnostic/verification support (as described for the SX‑A series).
• RoHS Compliant — Conforms to RoHS requirements for lead-free manufacturing.

Typical Applications

• PCI and Legacy Interface Logic — Use where configurable I/O and PCI-compliant signaling are required for bridging or endpoint logic.
• Mixed-Voltage System Integration — Ideal for designs that must interface across 2.5 V, 3.3 V, and 5 V domains due to the wide supply voltage support.
• Board-Level Glue and Control — Implements glue logic, protocol adaptations, and custom control functions using up to 1,452 logic elements and 113 I/Os.
• In-System Test and Verification — Supports boundary-scan and SX‑A in-system diagnostic capabilities for deployment and debug workflows.

Unique Advantages

• Balanced Logic Density: 24,000 system gates and 1,452 logic elements provide a mid-range capacity suited to a wide set of commercial FPGA tasks without excessive board cost.
• Flexible I/O Count: 113 user I/Os in a 144-pin package let you support multiple peripherals and external interfaces without moving to a larger package.
• Wide Voltage Range: 2.25 V to 5.25 V operation enables straightforward interfacing with legacy and modern logic levels.
• Nonvolatile Configuration: Single-chip nonvolatile architecture eliminates the need for external configuration memory and eases power sequencing.
• Standard SMT Package: 144-LQFP / 144-TQFP (20×20) package simplifies assembly on conventional PCBs while maintaining a compact footprint.
• RoHS Compliance: Lead-free packaging supports current manufacturing and environmental requirements.
