A54SX32A-1TQG144

The A54SX32A-1TQG144 is an SX-A family FPGA in a 144-pin LQFP package, offering a nonvolatile, single-chip programmable logic solution. It provides on-chip resources targeted for I/O‑intensive designs and mixed‑voltage interfaces.

As a –1 speed grade device, this part is specified to deliver approximately 15% faster performance than the standard grade and is characterized for commercial operation from 0 °C to 70 °C.

Key Features

• Logic Capacity — 48,000 system gates with 2,880 logic elements, enabling implementation of medium-complexity custom logic.
• I/O and Package — 113 user I/Os in a 144‑pin LQFP package (supplier device package: 144‑TQFP, 20×20); surface-mount construction for PCB assembly.
• Voltage Flexibility — 2.25 V to 5.25 V supply range with configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2; supports mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance — Family-level performance targets include up to 250 MHz system performance and up to 350 MHz internal performance.
• Power and I/O Robustness — Hot-swap compliant I/Os and power-up/power-down friendly operation (no supply sequencing required). Configurable weak pull-up or pull-down on I/Os at power-up and individual output slew-rate control.
• Configuration and Security — Nonvolatile single-chip configuration and Actel Secure Programming Technology (FuseLock™) to protect designs from reverse engineering.
• Debug and Test — In-system diagnostic and verification capability (Silicon Explorer II) and boundary-scan testing compliant with IEEE 1149.1 (JTAG).
• Compliance and Packaging — Commercial grade (0 °C to 70 °C) with RoHS compliance; available in the TQ package form factor specified for this part number.

Typical Applications

• PCI and Legacy Bus Interfaces — Configurable I/O support for 3.3 V/5 V PCI and TTL levels makes the device suitable for implementing bus interface logic and bridge functions.
• Mixed-Voltage Interface Glue Logic — Mixed-voltage operation and 5 V tolerant I/Os enable level translation and interface control between subsystems operating at 2.5 V, 3.3 V, and 5 V.
• In-System Programmable Control — Nonvolatile single-chip configuration and in-system diagnostics allow field updates and verification for embedded system control and peripheral management.
• Boundary-Scan and Test Integration — IEEE 1149.1 (JTAG) support simplifies board-level test access and manufacturing diagnostics.

Unique Advantages

• Compact, high-I/O package: 113 user I/Os in a 144‑pin LQFP package provide broad connectivity without increasing footprint.
• Flexible voltage support: Wide supply range and configurable I/O standards reduce the need for external level-shifting components in mixed-voltage systems.
• Nonvolatile configuration: Single-chip nonvolatile operation eliminates external configuration memory and simplifies power-up behavior.
• Security features: FuseLock™ secure programming protects intellectual property and prevents reverse engineering of the programmed design.
• Production-friendly testability: Boundary-scan (IEEE 1149.1) and in-system diagnostic tools aid manufacturing test and in-field verification.
• Commercial temperature characterization: Specified operation from 0 °C to 70 °C aligns this device with standard commercial electronics applications and environments.
