A54SX32A-2TQ144

The A54SX32A-2TQ144 is a member of the SX-A family of nonvolatile, single-chip FPGAs. It provides a mid-range programmable-logic resource set—approximately 48,000 system gates and 2,880 logic elements—along with 113 user I/O pins in a 144-pin LQFP/TQFP package.

Designed for applications that require mixed-voltage I/O, PCI compliance, and deterministic timing, the device delivers system performance up to 250 MHz and internal performance up to 350 MHz while supporting 2.5 V, 3.3 V and 5 V mixed-voltage operation.

Key Features

• Core Logic  Approximately 48,000 system gates and 2,880 logic elements provide flexible programmable logic capacity for mid-range designs.
• I/O and Interface Flexibility  113 user I/Os with configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; 5 V input tolerance and 5 V drive strength enable mixed-voltage board-level integration.
• Performance  System performance up to 250 MHz and internal performance reported up to 350 MHz for timing headroom in demanding logic paths.
• Nonvolatile Single-Chip Configuration  On-chip nonvolatile configuration removes the need for external configuration memory.
• Power and I/O Robustness  Hot-swap compliant I/Os and power-up/power-down friendly behavior (no sequencing required for supply voltages) simplify system power management.
• Security and Test  Actel Secure Programming technology with FuseLock™ for protection against reverse engineering, plus IEEE 1149.1 boundary-scan (JTAG) for board-level testability.
• Timing Control  Deterministic, user-controllable timing for predictable system behavior and timing closure.
• Package & Mounting  144-pin LQFP package (supplier device package: 144-TQFP 20×20); surface-mount mounting type.
• Power Supply & Temperature  Operating voltage range: 2.25 V to 5.25 V. Commercial temperature grade: 0 °C to 70 °C.
• Memory  Total on-chip RAM: 0 bits (no embedded RAM reported for this device).
• Compliance  RoHS compliant.

Typical Applications

• PCI-Compatible System Logic  Use for board-level logic and glue in systems requiring 66 MHz PCI compliance and mixed-voltage PCI signaling.
• Mixed-Voltage Interface Bridging  Ideal where 5 V-tolerant I/Os and 2.5/3.3/5 V mixed-voltage operation are required for interfacing disparate subsystems.
• Embedded System Control  Deterministic timing and single-chip nonvolatile configuration make it suitable for embedded control and application-specific logic functions.
• Systems Requiring Secure Configuration  Devices that need protection against IP extraction benefit from FuseLock secure programming technology.

Unique Advantages

• Highly integrated programmable logic: 48,000 system gates and 2,880 logic elements reduce the need for multiple discrete components and simplify board-level design.
• Versatile mixed-voltage I/O: Configurable I/O standards plus 5 V input tolerance and 5 V drive strength enable direct interfacing to a wide range of legacy and modern logic families.
• Nonvolatile single-chip solution: Eliminates external configuration memory, reducing BOM and improving reliability in deployed systems.
• Deterministic timing: User-controllable timing supports repeatable timing closure for critical signal paths.
• Built-in security and testability: FuseLock programming protection and IEEE 1149.1 JTAG boundary-scan aid IP protection and board-level diagnostics.
• Commercial-grade temperature and RoHS compliance: Commercial temperature range (0 °C to 70 °C) and RoHS-compliant manufacturing support standard commercial applications and regulatory requirements.
