A54SX08A-TQG144I

The A54SX08A-TQG144I is a member of the SX‑A family of Field Programmable Gate Arrays from Microchip Technology. This nonvolatile, single‑chip FPGA delivers 12,000 system gates with 768 logic elements and 113 user I/O pins in a 144‑pin LQFP package.

Designed for industrial applications, the device supports a wide supply range (2.25 V to 5.25 V) and an operating temperature range of −40 °C to 85 °C. Family features include hot‑swap compliant I/Os, power‑up/power‑down friendly behavior, PCI compliance, boundary‑scan (JTAG) testing, and in‑system diagnostic capabilities.

Key Features

• Core & Capacity 12,000 system gates and 768 logic elements provide a compact programmable fabric for control, glue logic, and moderate‑complexity custom logic functions. The device does not include on‑chip RAM (Total RAM Bits: 0).
• Performance SX‑A family performance characteristics include documented system performance up to 250 MHz and internal performance up to 350 MHz as specified for the family.
• I/O and Mixed‑Voltage Support 113 user I/Os with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2. I/Os are hot‑swap compliant and provide 5 V input tolerance and 5 V drive strength where supported by the family.
• Power & Voltage Wide supply voltage range (2.25 V to 5.25 V) plus power‑up/power‑down friendliness—no sequencing required for supply voltages—simplifies power system design.
• Security & Test Family features include Actel Secure Programming Technology with FuseLock™ to deter reverse engineering and design theft, and boundary‑scan testing compliant with IEEE 1149.1 (JTAG).
• Diagnostics & Tools Unique in‑system diagnostic and verification capability with Silicon Explorer II (family feature) enables on‑board debug and verification.
• Package & Temperature 144‑pin LQFP package and industrial temperature grade (−40 °C to 85 °C) make the device suitable for industrial environments requiring robust thermal operation.

Typical Applications

• Industrial Control — Use the industrial temperature rating, wide supply range and 113 I/Os for sensor interfacing, actuator control and real‑time I/O aggregation in control systems.
• Embedded Systems — Nonvolatile single‑chip FPGA eliminates the need for external configuration memory and supports compact embedded designs that require retained configuration and field programmability.
• PCI and Legacy Bus Interfaces — The family’s 66 MHz PCI compliance and mixed‑voltage I/O support enable bridging and interface logic for PCI and 5 V legacy systems.
• Secure, Testable Designs — FuseLock programming and IEEE 1149.1 boundary‑scan support simplify manufacturing test and help protect intellectual property.

Unique Advantages

• Nonvolatile, single‑chip solution: Eliminates the need for external configuration memory and simplifies system boot and board-level BOM.
• Flexible mixed‑voltage I/O: Configurable I/O standards and 5 V tolerance allow direct interfacing to a broad range of legacy and modern logic levels.
• Industrial robustness: Wide supply voltage range and −40 °C to 85 °C operating range support deployment in industrial environments.
• Deterministic timing and full utilization: SX‑A family features include deterministic, user‑controllable timing and support for up to 100% resource utilization with pin locking.
• Built‑in security and testability: FuseLock programming and IEEE‑1149.1 boundary‑scan support help protect designs and streamline production testing.
• On‑board diagnostic capability: Silicon Explorer II in‑system diagnostics enable board‑level verification and debugging during development and in the field.
