Key Features

• Core Performance  Approximately 48,000 system gates implemented as 2,880 logic elements, delivering the SX-A family’s quoted 250 MHz system and 350 MHz internal performance targets.
• I/O Flexibility  Up to 81 user I/Os with configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling; 5 V input tolerance and 5 V drive strength are supported at the series level.
• Nonvolatile Single-Chip  SX-A family single-chip, nonvolatile architecture enables in-system configuration without external configuration memory.
• Power and Voltage  Wide supply range (2.25 V to 5.25 V) and power-up/power-down friendly operation that requires no supply sequencing.
• System Reliability & Test  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability provided at the series level.
• Security and Programmability  Series-level secure programming technology (FuseLock™) to protect bitstream IP and prevent reverse engineering.
• Signal Control  Configurable weak pull-up/pull-down on I/O at power-up and individual output slew-rate control for signal integrity tuning.
• Package & Environmental  100-LQFP package (supplier device package listed as 100-TQFP, 14×14); surface-mount mounting; industrial operating temperature range −40 °C to 85 °C; RoHS compliant.
• Resource Utilization & Timing  Series-level support for up to 100% resource utilization and 100% pin locking with deterministic, user-controllable timing.

Typical Applications

• PCI-based systems  66 MHz PCI compliance at the series level supports integration into PCI and legacy bus applications that require programmable logic.
• Industrial embedded control  Industrial temperature rating (−40 °C to 85 °C) and robust I/O options suit embedded controllers and automation modules.
• Mixed-voltage interface designs  Wide supply range and multi-voltage I/O support enable bridging and interfacing between 5 V and lower-voltage domains.
• Secure in-system programmable logic  Nonvolatile, single-chip configuration combined with series-level secure programming enables field-updatable designs with protection against reverse engineering.

Unique Advantages

• Nonvolatile single-chip architecture: Eliminates the need for external configuration memory while enabling in-system programming and instant configuration on power-up.
• Wide supply and mixed-voltage I/O: 2.25 V to 5.25 V supply range plus multi-voltage I/O support allows flexible integration into diverse system power domains.
• Industrial temperature support: Specified for −40 °C to 85 °C operation for deployments in industrial environments.
• Deterministic timing control: Series-level deterministic, user-controllable timing supports designs that require predictable timing closure.
• Security features: FuseLock™ secure programming technology reduces the risk of reverse engineering and protects intellectual property.
• Comprehensive testability: Boundary-scan (IEEE 1149.1) and in-system diagnostic capabilities improve manufacturing test coverage and field diagnostics.
