A54SX16A-TQ144

The A54SX16A-TQ144 is a commercial-grade SX-A family Field Programmable Gate Array (FPGA) offered in a 144-pin thin quad flat pack (TQFP/LQFP-equivalent) surface-mount package. It delivers 24,000 system gates with 1,452 logic elements and 113 user I/Os, providing a compact, nonvolatile FPGA option for embedded systems that require flexible I/O, deterministic timing and in-system programmability.

With a wide supply range (2.25 V to 5.25 V), JTAG boundary-scan support and power-up/down friendly behavior, this device is suited to designs needing mixed-voltage I/O compatibility and secure, single-chip programmable logic in a 144-pin footprint.

Key Features

• Core Capacity — 24,000 system gates and 1,452 logic elements provide on-chip programmable logic for moderate-complexity designs.
• User I/O — 113 user-programmable I/O pins accommodate diverse peripheral interfacing and mixed-voltage signaling requirements.
• Voltage and I/O Flexibility — Supports supply operation from 2.25 V to 5.25 V and family-level configurable I/O for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling.
• Nonvolatile Single-Chip Solution — SX-A family architecture provides a nonvolatile FPGA implementation that maintains configuration without external memory.
• Performance — Family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical functions.
• System and Test Features — Boundary-scan (IEEE 1149.1/JTAG) support and in-system diagnostic capability improve board-level testability and verification.
• Power-Up/Down Friendly — No supply sequencing required for power-up/power-down, and configurable weak pull-up/pull-down options for I/O at power-up.
• Package & Mounting — 144-pin thin QFP (TQFP) surface-mount package, compliant with RoHS requirements.
• Commercial Temperature Grade — Rated for operation from 0 °C to 70 °C to match commercial embedded application needs.
• Security & Reliability — Family-level secure programming technology and deterministic, user-controllable timing for predictable operation.
• On-chip Memory — Total on-chip RAM bits: 0 (no embedded RAM), enabling designs that rely on distributed logic or external memory.

Typical Applications

• PCI and Bus Interface Logic — 3.3 V / 5 V PCI compatibility and flexible I/O make the device suitable for glue logic, protocol bridging and custom bus interfaces.
• Embedded Control and Glue Logic — 1,452 logic elements and 113 I/Os support control logic, state machines and I/O aggregation in compact embedded systems.
• Board-Level Test and In-System Programming — JTAG boundary-scan and in-system diagnostic features simplify manufacturing test and field reprogramming.
• Mixed-Voltage Systems — Support for multiple I/O voltage standards enables integration between legacy 5 V devices and modern lower-voltage peripherals.

Unique Advantages

• Compact, Nonvolatile FPGA: Provides single-chip configuration retention without external configuration memory, reducing bill-of-materials and board complexity.
