Key Features

• Core Performance  Rated SX family performance with up to 250 MHz system performance and up to 350 MHz internal performance; supplied in the –1 speed grade (approximately 15% faster than standard).
• Logic Resources  Provides 48,000 system gates and 2,880 logic elements to implement glue logic, state machines and custom datapaths.
• I/O and 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; 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 external configuration memory and enables immediate operation after power-up.
• System and Test Support  Hot-swap compliant I/Os, boundary-scan (IEEE 1149.1/JTAG) support and in-system diagnostic capability are included for testability and diagnostics.
• Power and Supply  Operates from a wide supply range of 3 V to 5.5 V and is power-up/power-down friendly with no required sequencing of supply voltages.
• Package and Temperature  Supplied in a 144-pin LQFP (listed as 144‑TQFP, 20×20) surface-mount package and rated for industrial operation from −40°C to 85°C.
• Security and IP Protection  Includes on-device secure programming technology to protect designs from reverse engineering and unauthorized copying.
• Compliance  RoHS compliant.

Typical Applications

• PCI and Bus Interface Logic  66 MHz PCI compliance and configurable I/O levels make the device suitable for implementing PCI interfacing, bus bridging and legacy bus glue logic.
• Mixed-Voltage System Glue  Mixed-voltage I/O support and 5 V tolerance enable integration between 2.5 V, 3.3 V and 5 V domains for board-level interface logic.
• In-System Programmable Control  Nonvolatile, single-chip configuration allows deployment in systems that require field reprogrammability without external configuration memory.
• Testable Digital Designs  Boundary-scan and in-system diagnostics support make the device useful where testability and fault isolation are required during manufacturing and in-field service.

Unique Advantages

• Deterministic, user-controllable timing: Enables predictable timing closure for designs where timing determinism matters.
• Nonvolatile configuration: Eliminates external configuration components and simplifies board-level BOM and startup behavior.
• Wide I/O flexibility: Configurable I/O standards and mixed-voltage operation reduce the need for level translators and simplify multi-voltage designs.
• Industrial temperature rating: Qualified for −40°C to 85°C operation for deployment in industrial environments.
• Integrated test and security features: Boundary-scan, in-system diagnostics and on-device secure programming improve testability and protect IP.
• Compact package: 144-pin surface-mount LQFP (144‑TQFP 20×20) offers a space-efficient solution for board-level integration.
