Key device attributes include 950 logic elements, 400 CLBs, 12,800 bits of on-chip RAM, 113 I/O pins and an operating range suited to industrial environments (3 V to 3.6 V supply, –40 °C to 100 °C).

Key Features

• Core Logic 950 logic elements and 400 CLBs provide configurable digital logic capacity suitable for mid-density FPGA designs.
• Embedded Memory 12,800 total RAM bits of on-chip memory for state storage, buffering and small lookup tables.
• I/O Capacity 113 general-purpose I/O pins to support multiple external interfaces and signal connections.
• Gate Count Approximately 20,000 gates enabling a range of combinational and sequential logic implementations.
• Power Operates from a 3 V to 3.6 V supply to match common industrial supply rails.
• Package & Mounting 144-LQFP (supplier device package listed as 144-TQFP, 20×20) in a surface-mount form factor for PCB designs with moderate area constraints.
• Temperature & Grade Industrial grade device with an operating temperature range of –40 °C to 100 °C for deployment in demanding environments.
• Environmental Compliance RoHS compliant.

Typical Applications

• Industrial Control Modules Industrial-grade temperature range and robust I/O count suit machine control, PLC front-ends and factory automation tasks.
• I/O Expansion and Glue Logic 113 I/O pins and configurable logic are useful for consolidating interface translation, bus bridging and peripheral control.
• Embedded Logic Prototyping Mid-density logic resources and on-chip RAM support prototyping of custom digital functions and algorithm offload.

Unique Advantages

• Balanced Logic Density: 950 logic elements and 400 CLBs provide a practical balance between capacity and footprint for mid-range designs.
• Generous I/O Count: 113 I/O pins allow flexible interfacing without external I/O expanders, simplifying board-level design.
• Industrial Qualification: Rated for –40 °C to 100 °C and listed as industrial grade, supporting deployment in demanding environments.
• Compact Surface-Mount Package: 144-LQFP (20×20 TQFP variant) enables a compact PCB implementation while retaining through-life manufacturability.
• Standards-Friendly Power Range: 3 V to 3.6 V supply compatibility aligns with common industrial and embedded power rails.
• Regulatory Compliance: RoHS compliance supports environmentally conscious product requirements.
