A54SX16A-FTQ144

The A54SX16A-FTQ144 is a member of the SX-A family of nonvolatile FPGAs from Microchip Technology. It provides reprogrammable logic in a single-chip, surface-mount package and is aimed at designs that require configurable I/O, on-chip logic resources and robust board-level testability.

As part of the SX-A family, this device combines a 24,000-system-gate capacity with approximately 1,452 logic elements and up to 113 user I/O pins (144-pin package), making it suitable for embedded control, I/O interfacing and PCI-capable system logic.

Key Features

• Logic Capacity — Approximately 24,000 system gates and 1,452 logic elements for medium-complexity logic integration and glue logic consolidation.
• User I/O — 113 user I/O pins in the 144-pin package to support diverse external interfaces and board-level connectivity.
• Voltage and I/O Flexibility — Device supplies supported from 2.25 V to 5.25 V; SX-A family supports configurable I/O levels and mixed-voltage operation (family-level feature).
• Nonvolatile Single-Chip Solution — SX-A family devices are described as nonvolatile single-chip solutions, removing the need for external configuration memory (family-level).
• Package and Mounting — 144-LQFP package case with surface-mount mounting; supplier device package listed as 144-TQFP (20×20).
• Operating Range — Commercial grade with operating temperature 0 °C to 70 °C.
• No Embedded RAM — Total on-chip RAM bits reported as 0; logic resources are provided as combinational and registered elements.
• Board Test and Security (Family Features) — SX-A family includes boundary-scan (IEEE 1149.1/JTAG) for board-level testability and Actel Secure Programming Technology (FuseLock™) for protection against reverse engineering (family-level features).
• Regulatory — RoHS compliant.

Typical Applications

• PCI and Peripheral Logic — Use in PCI-capable system logic and peripheral glue where configurable I/O and PCI signaling are required (SX-A family supports 66 MHz PCI).
• I/O Level Translation and Interface Bridging — Practical for designs that require configurable mixed-voltage I/O and board-level protocol interfacing.
• Embedded Control and Glue Logic — Medium-complexity control functions and signal aggregation using the device’s ~1,452 logic elements and 113 I/Os.
• Board Test and In-System Debug — Boundary-scan and SX-A family in-system diagnostic capabilities support manufacturing test and in-field verification.

Unique Advantages

• Right-sized Logic Capacity: 24,000 system gates and ~1,452 logic elements offer a balance between integration and cost for medium-complexity designs.
• Flexible I/O and Voltage Support: Wide supply range (2.25 V–5.25 V) and family-level mixed-voltage I/O support reduce the need for external level shifters and simplify mixed-signal board designs.
• Nonvolatile, Single-Chip Architecture: Eliminates external configuration memory, simplifying system boot and reducing BOM count (family-level attribute).
• Manufacturing and Field Testability: Boundary-scan (JTAG) and in-system diagnostics help streamline production test and firmware validation.
• Security Options: Family-level secure programming (FuseLock™) provides a mechanism to protect programmed designs against reverse engineering.
• RoHS Compliance: Meets RoHS requirements for environmentally conscious product designs and procurement.
