A54SX16A-1TQ144

The A54SX16A-1TQ144 is a member of the SX-A family of nonvolatile single-chip FPGAs. This commercial-grade device provides 24,000 system gates implemented as 1,452 logic elements with 113 user I/Os in a 144-pin package.

Designed for mixed-voltage embedded and interface applications, the device offers configurable I/O support and family-level features such as hot-swap–capable I/Os, JTAG boundary-scan, and on-chip security options tailored for designs that require deterministic timing and persistent configuration.

Key Features

• Logic Capacity — 24,000 system gates realized as 1,452 logic elements for medium-complexity gate-array designs.
• User I/O — 113 user-programmable I/Os with configurable I/O support for mixed-voltage operation and 5 V input tolerance.
• Nonvolatile Single-Chip Configuration — Family-level single-chip nonvolatile architecture provides persistent configuration without external configuration memory.
• Performance — Family data cites up to 250 MHz system performance and up to 350 MHz internal performance for timing-sensitive logic.
• Voltage and Power — Wide supply range from 2.25 V to 5.25 V and power-up/power-down friendly behavior that requires no sequencing of supply voltages.
• Package and Mounting — 144-pin LQFP package (supplier device package: 144-TQFP, 20 × 20); surface-mount mounting type suitable for PCB assembly.
• Temperature and Grade — Commercial temperature grade, rated 0 °C to 70 °C.
• Security and Test — Family features include Actel Secure Programming technology with FuseLock™ for protection against reverse engineering and IEEE 1149.1 JTAG boundary-scan testing support.
• RoHS Compliance — Device is RoHS compliant.
• On-chip Memory — No embedded RAM (total on-chip RAM bits: 0), enabling predictable resource planning for designs that use external memory or register-based logic.

Typical Applications

• Mixed-Voltage Interface Bridging — Use the device’s configurable I/Os and 5 V tolerance to bridge between 5 V and lower-voltage logic domains for legacy interface support.
• PCI-Compatible System Logic — The family’s 66 MHz PCI compliance and configurable I/O make the device suitable for implementing PCI-compliant glue logic and interface control.
• Embedded Control and Glue Logic — 1,452 logic elements provide capacity for state machines, protocol handling, and peripheral control in embedded systems.
• Designs Requiring Persistent Configuration — Nonvolatile single-chip configuration is suited for applications that need immediate-on programmable logic without external configuration memory.

Unique Advantages

• Persistent, Single-Chip FPGA: Eliminates the need for external configuration memory, simplifying the bill of materials and board-level design.
• Mixed-Voltage Flexibility: Support for 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance enables flexible interfacing to multiple voltage domains.
• Security Features: FuseLock™ secure programming reduces risk of reverse engineering and protects intellectual property in deployed systems.
• Testability and Diagnostics: IEEE 1149.1 JTAG boundary-scan and family in-system diagnostic/verification capabilities support production testing and field troubleshooting.
• Predictable Resource Model: Fixed logic element count and no embedded RAM simplify resource planning and deterministic timing analysis for control-dominated designs.
• RoHS Compliant: Supports regulatory requirements for lead-free assemblies.
