AT40K20-2FQI

The AT40K20-2FQI is a Field Programmable Gate Array (FPGA) IC designed for industrial embedded applications. It provides 1,024 logic elements, approximately 8,192 bits of on-chip RAM and support for up to 256 I/O pins in a 304-pin BFQFP surface-mount package.

With an operating range of 4.5 V to 5.5 V and an industrial temperature rating from -40 °C to 85 °C, the device targets systems that require moderate logic density, flexible I/O connectivity and operation across extended temperature conditions.

Key Features

• Core Logic 1,024 logic elements (cells) providing roughly 30,000 equivalent gates for implementing custom logic and glue functions.
• Embedded Memory Approximately 8,192 bits of on-chip RAM for small FIFOs, state storage and buffering tasks.
• I/O Capacity Up to 256 I/O pins to support broad connectivity and multiple peripheral interfaces.
• Package & Mounting 304-BFQFP (supplier package: 304-PQFP, 40×40) in a surface-mount form factor for compact PCB layouts.
• Power Single-supply operation from 4.5 V to 5.5 V, compatible with standard 5 V systems.
• Temperature Range Industrial-grade operation from -40 °C to 85 °C for deployment in temperature-challenging environments.
• Regulatory RoHS compliant.

Typical Applications

• Industrial Control — Implement custom control logic, I/O aggregation and interface translation in industrial equipment, leveraging the industrial temperature rating and 256 I/O capability.
• Embedded Systems — Integrate glue logic, peripheral interfacing and small-scale state machines where moderate logic density and on-chip RAM meet design needs.
• Prototyping and Evaluation — Use the device for proof-of-concept designs that require reconfigurable logic, multiple I/O and compact packaging for board-level testing.

Unique Advantages

• Balanced Logic Density: 1,024 logic elements and roughly 30,000 gates provide a practical trade-off between capacity and cost for moderate-complexity designs.
• Generous I/O Count: 256 I/O pins enable integration of multiple peripherals and interfaces without external expanders.
• Compact, Surface-Mount Package: The 304-BFQFP (40×40) package supports high pin-count routing while minimizing PCB footprint.
• 5 V System Compatibility: 4.5 V to 5.5 V supply range allows straightforward integration into existing 5 V designs and power rails.
• Industrial Temperature Capability: Rated for -40 °C to 85 °C operation to meet the requirements of temperature-demanding deployments.
• RoHS Compliant: Meets common environmental requirements for modern electronics manufacturing.
