Key Features

• Logic Capacity — 24,000 system gates and approximately 1,452 logic elements provide mid-range programmable logic density for control, glue-logic and interface tasks.
• User I/O — 113 user-programmable I/Os in a 144-LQFP package, with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling.
• Voltage Flexibility — Operates across a 2.25 V to 5.25 V supply range and supports mixed-voltage operation with 5 V input tolerance and 5 V drive strength where specified.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (series-level specification).
• Nonvolatile Single-Chip Solution — On-chip nonvolatile configuration removes the need for external configuration memory and enables immediate start-up behavior described in the family datasheet.
• System and Test Support — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability with Silicon Explorer II (series-level features).
• Security — Actel Secure Programming Technology with FuseLock™ is documented for the SX-A family to help protect designs from reverse engineering (series-level feature).
• Package and Mounting — Supplied in a 144-pin LQFP (thin quad flat pack/TQFP equivalent) surface-mount package (20 × 20 mm supplier package reference).
• Commercial Temperature Grade — Rated for operation from 0 °C to 70 °C.

Typical Applications

• PCI and Interface Bridging — Configurable I/O with 3.3 V / 5 V PCI support suits the device for PCI-based interface and bridging functions.
• Embedded Control and Glue Logic — Mid-range logic capacity and flexible I/O voltage support make the device appropriate for control, state machines and board-level glue logic.
• In-System Diagnostics and Verification — Built-in boundary-scan and in-system diagnostic capabilities support development, field verification and manufacturing test flows.

Unique Advantages

• Nonvolatile, Single-Chip Configuration: Eliminates the need for external configuration memory, simplifying BOM and board design.
• Flexible I/O Voltage Support: Mixed-voltage operation and 5 V input tolerance enable direct interfacing with a range of legacy and modern logic standards.
• Integrated Test and Security Features: IEEE 1149.1 boundary-scan and FuseLock™ secure programming provide testability and design protection at the device level.
• Deterministic, Controllable Timing: Series-level SX-A timing features support predictable timing closure and system-level timing control.
• Commercial Temperature and Surface-Mount Packaging: 0 °C to 70 °C rating and a 144-pin surface-mount package facilitate board-level integration for commercial products.
