A54SX08-1FG144I

The A54SX08-1FG144I is a nonvolatile SX family FPGA offering a compact, surface-mount 144-LBGA package with industrial-grade operation. It delivers 12,000 system gates implemented across 768 logic elements and provides 111 user I/Os for mixed-voltage interfacing.

Designed for embedded systems and industrial electronics, this device combines deterministic timing, flexible I/O support and on-chip security features to simplify board-level design and in-system configuration.

Key Features

• Core Capacity — 12,000 system gates implemented as approximately 768 logic elements, suitable for moderate-density glue logic, protocol bridges and control functions.
• High-Speed Performance — SX family documented system performance up to 250 MHz and internal performance up to 350 MHz for timing-critical paths.
• I/O Flexibility — 111 user I/Os with configurable support for multiple standards including 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.
• Nonvolatile Single-Chip Solution — On-chip nonvolatile configuration removes the need for an external configuration PROM, simplifying BOM and power-up behavior.
• Robust System Features — Hot-swap compliant I/Os, configurable weak pull-up/pull-down at power-up, individual output slew-rate control, and deterministic, user-controllable timing.
• Security & Test — Actel Secure Programming Technology with FuseLock prevents reverse engineering; boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification via Silicon Explorer II.
• Package & Mounting — Surface-mount 144-LBGA (supplier package: 144-FPBGA (13x13)), enabling compact board designs.
• Voltage & Temperature — Wide supply range from 3 V to 5.5 V and industrial operating temperature range of −40 °C to 85 °C.

Typical Applications

• Industrial Control — Implement deterministic control logic and protocol conversion for factory automation and motor control systems that require industrial temperature operation.
• Interface Bridging — Use the flexible I/O and mixed-voltage support to build PCI or legacy interface bridges and board-level translators.
• Embedded Instrumentation — Integrate custom signal processing, control sequencing, and I/O aggregation in test and measurement equipment.
• Secure Systems — Leverage on-chip nonvolatile configuration and FuseLock technology for designs that require protection against reverse engineering and secure in-field updates.

Unique Advantages

• Single-Chip Nonvolatile Configuration: Eliminates external configuration memory and simplifies power-up sequencing and board-level BOM.
• Flexible, Mixed-Voltage I/O: Reduces the need for level translators by supporting multiple I/O standards and 5 V tolerance/drive.
• Deterministic Timing Control: User-controllable timing features help designers meet tight timing budgets without guesswork.
• Security Built In: FuseLock secure programming technology provides protection against reverse engineering and unauthorized readback.
• Industrial Ready: Rated for operation from −40 °C to 85 °C and a wide 3 V to 5.5 V supply range for reliable operation in industrial environments.
