A42MX09-1PL84I

The A42MX09-1PL84I is an MX-series Field Programmable Gate Array (FPGA) from Microchip Technology, delivering reconfigurable logic in a compact 84‑lead PLCC (J‑Lead) package. It combines programmable logic resources and a substantial I/O count to address embedded control and interface duties in industrial applications.

Designed for operation across a broad supply range (3 V to 5.5 V) and an industrial temperature window (‑40 °C to 85 °C), this device is suited for designs that require moderate logic capacity, flexible I/O, and surface-mount packaging for board-level integration.

Key Features

• FPGA Core MX field-programmable architecture providing 336 logic elements to implement custom logic and control functions.
• Logic Capacity Approximately 14,000 gates worth of programmable logic for glue-logic, protocol adaptation, and control tasks.
• I/O 72 user I/O pins to support multiple peripheral interfaces, sensor inputs, and system control lines.
• Memory No embedded RAM (0 bits), suitable for applications that rely on external memory or are primarily combinational/state-machine based.
• Power Flexible supply range from 3 V to 5.5 V to accommodate a variety of system power rails.
• Package & Mounting 84‑lead LCC (J‑Lead) / 84‑PLCC supplier device package (29.31 × 29.31 mm) in a surface-mount form factor for PCB assembly.
• Temperature & Grade Industrial grade operation from ‑40 °C to 85 °C for use in standard industrial environments.
• Compliance RoHS compliant.

Typical Applications
