A42MX09-2PLG84I

The A42MX09-2PLG84I is a field programmable gate array (FPGA) IC from Microchip Technology designed for moderate-density digital logic and I/O-driven designs. It combines a compact surface-mount 84‑lead J‑lead package with industrial-grade temperature and supply tolerances to address embedded control and interface tasks in industrial environments.

Key attributes include a modest logic capacity, a 72‑pin I/O count, wide supply voltage range and RoHS compliance—making the device suitable for designs that require programmable logic, flexible I/O handling and reliable operation across −40 °C to 85 °C.

Key Features

• Core Logic  336 logic elements and approximately 14,000 gates provide programmable combinational and sequential resources for glue logic, protocol handling and control functions.
• I/O Capability  72 user I/O pins allow direct interfacing to a range of peripherals, sensors and bus signals in system designs.
• On‑chip Memory  Total on‑chip RAM: 0 bits (no embedded RAM), suitable for applications that use external memory or do not require on‑chip data storage.
• Power and Voltage  Operates from a wide supply range of 3 V to 5.5 V to accommodate common industrial logic rails and mixed-voltage systems.
• Package and Mounting  84‑lead LCC (J‑Lead) surface‑mount package; supplier device package listed as 84‑PLCC (29.31 × 29.31 mm) for compact board-level implementation.
• Environmental and Grade  Industrial grade with an operating temperature range of −40 °C to 85 °C and RoHS compliance for regulatory and environmental requirements.

Typical Applications

• Industrial Control  Implement control logic, state machines and I/O consolidation for automation equipment requiring industrial temperature operation.
• I/O Interfacing and Glue Logic  Bridge peripherals and custom buses using the device’s 72 I/O pins to centralize signal translation and timing functions.
• Prototyping and Low‑Density Logic  Rapidly deploy programmable logic for functional prototypes or production systems that need modest gate and logic element counts.

Unique Advantages

• Balanced Logic Density: 336 logic elements and ~14,000 gates provide adequate resources for many embedded control and interfacing tasks without excess overhead.
• Generous I/O Count: 72 I/O pins let designers consolidate external glue logic and reduce discrete component count on board-level designs.
• Wide Supply Compatibility: Supports 3 V to 5.5 V supplies to integrate with common industrial and legacy voltage domains.
• Industrial Temperature Range: Rated for −40 °C to 85 °C operation to meet environmental demands of industrial installations.
• Compact, Surface‑Mount Package: 84‑lead J‑lead LCC/PLCC footprint enables dense PCB layouts while supporting surface‑mount assembly.
• RoHS Compliant: Conforms to RoHS requirements for environmental and regulatory compatibility.
