A54SX72A-2FG484I

The A54SX72A-2FG484I is a nonvolatile SX-A family FPGA in a 484‑ball fine-pitch BGA package designed for industrial-temperature applications. It provides 108,000 system gates and 6,036 logic elements to implement complex digital functions with configurable I/O and deterministic timing control. Typical use cases include system glue logic, PCI‑compatible interfaces, embedded control, and in-system diagnostics where mixed-voltage I/O, nonvolatile single‑chip configuration and robust I/O options are required.

Key Features

• Core Capacity — 108,000 system gates and approximately 6,036 logic elements, enabling complex logic integration on a single device.
• Flip‑Flop Resources — Up to 2,012 dedicated flip‑flops (with higher maximum flip‑flop counts achievable per device configuration options), supporting register-rich designs and state-machine implementations.
• Performance — System performance up to 250 MHz and internal performance up to 350 MHz as specified for the SX‑A family.
• I/O and Interface Flexibility — Up to 360 user‑programmable I/O pins with configurable support for 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling; hot‑swap compliant and power‑up/-down friendly I/Os.
• Mixed‑Voltage Operation — Supports 2.5 V, 3.3 V and 5 V mixed‑voltage operation with 5 V input tolerance and 5 V drive strength where required by the design.
• Power and Availability — Single‑chip, nonvolatile FPGA architecture that does not require supply sequencing and supports hot‑swap I/O scenarios.
• Package and Thermal — 484‑ball fine‑pitch BGA (1.0 mm) in a 27 × 27 mm format; industrial temperature grade with operating range of −40 °C to +85 °C.
• Voltage Supply — Operates across a wide supply range from 2.25 V to 5.25 V to accommodate diverse system domains.
• System Reliability and Test — Boundary‑scan testing compliant with IEEE 1149.1 (JTAG) and in‑system diagnostic/verification capability with Silicon Explorer II.
• Security — Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering and design theft.
• Standards Compliance — 66 MHz PCI‑compliant signaling supported by the SX‑A family.

Typical Applications

• PCI and Peripheral Interfaces — Implement PCI bridge logic and custom peripheral interfaces using the device’s PCI‑capable, mixed‑voltage I/O and 66 MHz support.
• System Glue and Control — Replace discrete glue logic and CPLDs with integrated programmable logic to reduce board complexity and part count.
• Embedded Control and State Machines — Use dedicated flip‑flops and abundant logic elements to implement control paths, protocol handlers, and state machines.
• In‑System Diagnostics and Production Test — Leverage boundary‑scan and Silicon Explorer II support for board-level test, debug and field diagnostics.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Eliminates external configuration memory and simplifies board-level power sequencing and system bring‑up.
• Wide I/O Flexibility: Configurable I/O standards and 5 V tolerance provide direct interfacing to a variety of legacy and modern peripherals without additional level‑shifters.
• Industrial Temperature Rating: Rated for −40 °C to +85 °C operation, suitable for industrial control and embedded applications requiring extended temperature range.
• Robust Security: FuseLock programming technology helps protect intellectual property and prevents unauthorized design extraction.
• High Integration Density: 108,000 system gates and 6,036 logic elements allow consolidation of multiple discrete functions into one device, reducing BOM and board area.
• Deterministic Timing and Testability: User‑controllable timing and IEEE‑1149.1 boundary‑scan support simplify timing closure and manufacturing test strategies.
