A42MX16-3PLG84I

The A42MX16-3PLG84I is an MX series Field Programmable Gate Array (FPGA) from Microchip Technology designed for industrial-grade embedded logic applications. It provides a mid-range logic capacity with 608 logic elements and approximately 24,000 gates, along with 72 general-purpose I/O pins for flexible interfacing.

Designed for surface-mount assembly in an 84‑lead LCC/PLCC package, the device operates from 3 V to 5.5 V and across an industrial temperature range of -40 °C to 85 °C, offering a balance of integration and environmental robustness for industrial and embedded system designs.

Key Features

• Core Capacity  Provides 608 logic elements and approximately 24,000 gates to implement custom logic, glue-logic, and mid-density FPGA functions.
• I/O  72 user I/O pins support a variety of external interfaces and peripheral connectivity within a compact footprint.
• Memory  No on‑chip RAM (Total RAM Bits: 0), making the part suitable for designs that use external memory or require primarily combinational and registered logic.
• Power  Wide supply range from 3 V to 5.5 V enables compatibility with common industrial and legacy supply rails.
• Package & Mounting  84‑lead LCC (J‑Lead) / 84‑PLCC (29.31 × 29.31 mm) in a surface‑mount configuration for PCB assembly and compact board-level integration.
• Temperature & Grade  Industrial grade operation from -40 °C to 85 °C for use in temperature‑sensitive environments.
• Compliance  RoHS compliant for environmental and regulatory conformance in modern electronic assemblies.

Typical Applications

• Industrial Control  Suitable for industrial automation and control logic where the industrial temperature rating and wide supply range are required.
• Embedded Systems  Use as on‑board glue logic, custom interfacing, or protocol handling in embedded products that need mid-range logic density and numerous I/O.
• Communications and I/O Bridging  Implement custom interface bridging or pre/post processing tasks that leverage the 72 available I/Os and programmable logic resources.
• Prototyping and Custom Logic  A compact surface‑mount PLCC package and moderate gate count make the device suitable for prototypes and specialized logic functions in production designs.

Unique Advantages

• Balanced Logic Density: 608 logic elements and ~24,000 gates provide sufficient capacity for mid‑range custom logic without excessive complexity.
• Flexible I/O Count: 72 pins of user I/O enable integration with multiple peripherals and sensors while minimizing external glue components.
• Wide Supply Compatibility: Operation from 3 V to 5.5 V simplifies integration into systems with standard industrial and legacy power rails.
• Industrial Temperature Range: -rated operation from -40 °C to 85 °C supports deployment in demanding environments.
• Compact Surface-Mount Package: 84‑lead LCC/PLCC in a surface‑mount form factor reduces board area and supports automated assembly.
• RoHS Compliant: Meets RoHS requirements for environmentally conscious manufacturing and global market acceptance.
