A54SX08A-2TQ100

The A54SX08A-2TQ100 is a commercial-grade, nonvolatile SX-A family FPGA provided in a 100-pin LQFP surface-mount package. It delivers 12,000 system gates with 768 logic elements and 81 user I/Os, targeted at mid-density logic integration and I/O control in commercial embedded systems.

Designed for mixed-voltage environments and flexible I/O configurations, this device offers a compact, single-chip solution for designers needing deterministic timing, onboard security, and PCI-capable interfacing in a 0 °C to 70 °C operating range.

Key Features

• Core Capacity — 12,000 system gates and 768 logic elements provide mid-density programmable logic suitable for glue logic, control functions, and I/O aggregation.
• User I/O — 81 user-programmable I/Os in the 100-pin package, with configurable weak pull-up/pull-down and individual output slew-rate control for signal integrity tuning.
• Nonvolatile Single-Chip Architecture — Built-in nonvolatile configuration eliminates the need for external configuration memory and supports in-system programming and diagnostics.
• Performance — Series specifications cite up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical logic paths.
• Mixed-Voltage I/O Support — Configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2; devices support 2.5 V, 3.3 V, and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Power and Reliability — Hot-swap compliant I/Os and power-up/power-down friendly behavior (no sequencing required for supply voltages) simplify system power management.
• Security and Testability — Actel Secure Programming Technology with FuseLock™ helps protect design IP; IEEE 1149.1 (JTAG) boundary-scan testing supported for board-level test strategies.
• Package & Mounting — Surface-mount 100-LQFP package; supplier device package referenced as 100-TQFP (14×14 mm) for compact PCB implementations.
• Power Supply & Temperature — Operates from 2.25 V to 5.25 V and rated for commercial temperature range 0 °C to 70 °C.
• On-Chip Memory — No embedded RAM (Total Ram Bits: 0), enabling predictable resource allocation for purely logic-centric designs.

Typical Applications

• Embedded control and sequencing — Mid-density programmable logic for control functions, state machines, and custom timing in commercial equipment.
• I/O aggregation and level translation — Mixed-voltage I/O support and 81 user I/Os simplify interfacing between subsystems and reduce external level-shifter requirements.
• PCI peripheral glue logic — Series-level 66 MHz PCI compliance supports peripheral interfacing and legacy bus bridging in commercial systems.
• Secure configuration and in-system verification — Nonvolatile configuration with FuseLock and in-system diagnostic capabilities enable protected designs and on-board verification flows.

Unique Advantages

• Compact mid-density integration: 12,000 system gates and 768 logic elements provide a balance of capacity and footprint for many commercial embedded designs.
• Single-chip nonvolatile solution: Eliminates external configuration memory and simplifies board-level design and supply sequencing.
• Flexible mixed-voltage I/O: Native support for multiple I/O standards and 5 V-tolerant inputs reduces BOM and eases integration with legacy and modern interfaces.
• Built-in security and test features: FuseLock programming technology and IEEE 1149.1 boundary-scan improve IP protection and manufacturability.
• Deterministic performance and diagnostics: Documented system/internal performance figures and in-system diagnostic tools support predictable timing and validation workflows.
• Commercial temperature and broad supply range: 0 °C to 70 °C operating range and 2.25 V–5.25 V supply compatibility fit standard commercial product requirements.
