A3P125-FGG144I

The A3P125-FGG144I is a ProASIC3 field programmable gate array (FPGA) from Microchip Technology designed for industrial applications. It delivers 3,072 logic elements and 36,864 bits of on-chip RAM in a compact 144-LBGA package, providing a balance of logic density, embedded memory, and I/O for mid-range programmable logic requirements.

With a 97-pin I/O complement, a supply voltage range of 1.425 V to 1.575 V, and an operating temperature range of −40 °C to 100 °C, the device is suited for embedded systems that require industrial temperature performance and surface-mount packaging.

Key Features

• Core Logic  3,072 logic elements (LEs) and 125,000 gates provide programmable logic capacity for glue logic, datapath functions, and custom control algorithms.
• On‑Chip Memory  36,864 bits of embedded RAM for buffering, small FIFOs, and local storage to support state machines and temporary data storage.
• I/O and Integration  97 general-purpose I/Os enable connectivity to sensors, peripherals, and external devices in compact system designs.
• Power  Operates from a nominal supply range of 1.425 V to 1.575 V, suitable for regulated system rails.
• Package and Mounting  144-LBGA package (supplier device package: 144-FPBGA 13×13) in a surface-mount form factor for space-efficient board integration.
• Industrial Temperature Range  Rated for −40 °C to 100 °C operation to meet industrial environmental requirements.
• Regulatory  RoHS compliant for lead-free manufacturing and environmental compliance.

Typical Applications

• Industrial Control  Use for control logic, I/O aggregation, and timing functions in factory automation and process-control modules where industrial temperature range is required.
• Embedded System Glue Logic  Implement custom interfacing, bus bridging, and multiplexing between microcontrollers, sensors, and peripherals with the device’s ample I/O and logic elements.
• Signal Conditioning and Preprocessing  Small buffering and preprocessing of sensor or peripheral data using on-chip RAM and programmable logic before handing data to a host processor.

Unique Advantages

• Balanced Logic and Memory:  3,072 logic elements combined with 36,864 bits of RAM offers designers the flexibility to implement control logic and local data storage without external memory for many mid-range designs.
• Compact, Surface-Mount Package:  The 144-LBGA (144-FPBGA 13×13) package enables high-density board layouts and reliable solder mounting for volume production.
• Industrial-Grade Operating Range:  Specified operation from −40 °C to 100 °C supports deployment in harsh or thermally demanding environments.
• Generous I/O Count:  97 I/Os simplify integration with multiple peripherals and sensors, reducing the need for external I/O expanders.
• Stable Supply Window:  Narrow supply range (1.425 V–1.575 V) helps ensure predictable power behavior in regulated system designs.
• RoHS Compliant:  Meets lead-free manufacturing requirements for environmentally conscious production.
