Key Features

• Core Logic Approximately 2,880 logic elements (combinatorial cells) and a typical capacity of 48,000 gates provide mid-range programmable logic resources suitable for control and interface functions.
• Programmable Registers Dedicated flip-flop resources (as provided in the SX-A family) support synchronous designs and deterministic timing.
• I/O Flexibility Up to 81 user-programmable I/Os on the 100-pin package; configurable I/O support for 3.3 V PCI, 3.3 V LVTTL and 2.5 V LVCMOS2 as defined by the SX-A family.
• Voltage and Power Wide supply voltage range from 2.25 V to 5.25 V enables interfacing with diverse system rails without special sequencing required at power-up or power-down.
• Automotive Qualification Automotive grade with AEC-Q100 qualification and an operating temperature range of −40 °C to 125 °C for demanding vehicle environments.
• Performance & Timing Family-level characteristics include internal performance up to 250 MHz and deterministic, user-controllable timing for predictable system behavior.
• Nonvolatile Configuration Nonvolatile single-chip architecture retains configuration without external configuration memory.
• System Test & Security Family features include boundary-scan (IEEE 1149.1 JTAG) for test and Actel’s Secure Programming Technology (FuseLock™) to protect designs.
• Package & Mounting 100-pin TQFP/LQFP surface-mount package (14×14 mm supplier device package) for compact board integration.
• Standards & Interfaces SX-A family devices provide 66 MHz PCI compliance and hot-swap compliant I/Os as part of the device family feature set.

Typical Applications

• Automotive control modules AEC-Q100 qualification and −40 °C to 125 °C operating range support in-vehicle control and interface logic where robust thermal and electrical behavior is required.
• Sensor and actuator interfaces Configurable I/O levels and wide supply range enable direct interfacing to a variety of sensors and actuators within embedded systems.
• Deterministic timing functions On-chip dedicated registers and family-level deterministic timing suit timing-critical control and signal-processing tasks.

Unique Advantages

• Highly integrated mid-density FPGA: 48,000 system gates and 2,880 logic elements deliver substantial programmable logic in a compact 100-pin package to reduce BOM and board area.
