With 3,072 logic elements, approximately 36.9 kbits of on-chip RAM and 133 I/O, this device is designed for industrial applications that require configurable logic, flexible interfacing and operation across an industrial temperature range.

Key Features

• Core Logic  Provides 3,072 logic elements (LEs) and approximately 125,000 gates to implement custom digital functions and moderate-density logic designs.
• Embedded Memory  Includes approximately 36.9 kbits (36,864 bits) of on-chip RAM for buffering, small data tables and state storage.
• I/O Capacity  Offers 133 I/O pins to support multiple peripherals, parallel interfaces and mixed-signal front-end connections.
• Power  Operates from a core voltage range of 1.425 V to 1.575 V to match system power-rail requirements for core logic.
• Package & Mounting  Supplied in a 208-BFQFP / 208-PQFP (28×28) surface-mount package for board-level integration in compact footprints.
• Industrial Temperature Grade  Specified for operation from -40 °C to 100 °C, making it suitable for industrial environments and elevated-temperature applications.
• Regulatory  RoHS compliant, simplifying materials compliance for commercial and industrial product lines.

Typical Applications

• Industrial Control and Automation  Industrial-grade temperature specification and a sizable I/O count make this FPGA suitable for control logic, I/O aggregation and protocol adaptation in factory and process automation equipment.
• Interface and I/O Expansion  With 133 I/Os and a moderate logic resource, the device can implement custom interfacing, signal conditioning logic and protocol bridging between subsystems.
• Embedded System Logic  Provides configurable logic and embedded RAM for state machines, peripheral offload and custom timing or sequencing functions in embedded applications.

Unique Advantages

• Mid-range logic capacity: 3,072 logic elements and ~125k gates deliver the right balance of resources for moderate-complexity designs without overprovisioning.
• Generous I/O availability: 133 I/Os allow consolidation of multiple interfaces and reduce the need for external glue logic.
• Industrial operating range: Rated from -40 °C to 100 °C to meet the thermal demands of industrial deployments.
• Compact surface-mount package: 208-BFQFP (28×28) packaging supports dense PCB layouts while maintaining necessary pin count for complex I/O.
• Controlled core voltage: Defined supply window (1.425 V–1.575 V) supports predictable power budgeting and integration with system power rails.
• RoHS compliant: Simplifies compliance for environmental and manufacturing requirements.
