A54SX16A-1TQG144

The A54SX16A-1TQG144 is a commercial-grade, nonvolatile SX-A family FPGA from Microchip Technology. It delivers 24,000 system gates implemented across 1,452 logic elements with 113 user I/Os in a 144-pin LQFP/TQFP surface-mount package.

Designed for mixed-voltage embedded applications, the device supports a wide supply range (2.25 V to 5.25 V), provides in-system programmability and diagnostic capabilities, and inherits SX-A family characteristics such as hot-swap compliant I/Os and boundary-scan (JTAG) support.

Key Features

• Core Capacity — 24,000 system gates implemented as approximately 1,452 logic elements, suitable for glue logic, control glue, and medium-complexity FPGA functions.
• User I/O — 113 user-programmable I/Os with configurable I/O support for multiple signaling standards and 5 V input tolerance per SX-A family specifications.
• Nonvolatile Single-Chip Architecture — SX-A family single-chip, nonvolatile configuration that enables in-system programming and retains configuration without external memory.
• Voltage Flexibility — Supported supply range from 2.25 V to 5.25 V, enabling mixed-voltage system designs and interfacing with legacy 5 V logic.
• No Embedded RAM — Total RAM bits: 0, indicating the device is optimized for logic and flip‑flop based functions rather than distributed on-chip memory.
• Performance and Timing — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance, along with deterministic, user-controllable timing.
• Packaging & Mounting — 144-pin LQFP package case (supplier device package listed as 144-TQFP, 20×20); surface-mount mounting for board-level assembly.
• Reliability & Test — Boundary-scan testing (IEEE 1149.1/JTAG) support and family-level features such as power-up/down friendly behavior and configurable weak pull-up/pull-down on I/Os at power-up.
• Regulatory — RoHS-compliant.
• Operating Conditions — Commercial temperature grade with operating range 0 °C to 70 °C.

Typical Applications

• Mixed-Voltage Interface and Glue Logic — Use the device to bridge and interface between 5 V legacy logic and lower-voltage domains thanks to its wide supply range and 5 V input tolerance.
• PCI and Legacy Bus Adaptation — The SX-A family includes 66 MHz PCI compliance; this device can be applied where medium-speed PCI-compliant logic adaptation or buffering is required.
• Embedded Control and State Machines — Compact footprint and nonvolatile configuration make the device suitable for board-level control functions, protocol translation, and state-machine implementations.
• In-System Diagnostics & Production Test — Boundary-scan (JTAG) and family diagnostic capabilities support manufacturing test, in-system verification, and field diagnostics.

Unique Advantages

• Compact, Gate-Level Integration: 24,000 system gates and 1,452 logic elements deliver a mid-range integration point that reduces external glue components and simplifies board-level design.
• Mixed-Voltage Compatibility: Broad supply range (2.25 V–5.25 V) and configurable I/Os allow direct interfacing across multiple logic families, reducing level-shifter requirements.
• Nonvolatile Configuration: Single-chip nonvolatile architecture removes the need for external configuration memory and streamlines power-up behavior.
• Deterministic Timing and Testability: Family features such as user-controllable timing, JTAG boundary-scan, and in-system diagnostics improve system validation and maintainability.
• Surface-Mount Package for Compact Designs: 144-pin LQFP/TQFP surface-mount package enables a smaller PCB footprint while providing a generous I/O count for mid-complexity applications.
• RoHS-Compliant: Compliant with RoHS directives for lead-free manufacturing and environmental responsibility.
