A42MX09-PLG84M

The A42MX09-PLG84M from Microchip Technology is an MX family field programmable gate array (FPGA) supplied in an 84-lead PLCC (J-lead) package. It provides a compact, military-grade programmable logic option with 72 general-purpose I/O and a moderate logic capacity suitable for control, interface, and signal-processing tasks in rugged systems.

With a wide supply range and extended operating temperature, this FPGA targets applications that require reliable operation across demanding environments while preserving board-level density and integration.

Key Features

• Logic Capacity — 336 logic elements supporting approximately 14,000 gates for implementing custom combinational and sequential logic functions.
• I/O Count — 72 user I/O pins to support a variety of peripheral interfaces, sensor connections, and control signals.
• Memory — No on-chip RAM (Total Ram Bits: 0), enabling deterministic logic use and clear expectations for external memory requirements.
• Power — Operates across a broad supply range from 3 V to 5.5 V, accommodating common system voltage domains.
• Package & Mounting — 84-lead PLCC (J-lead) surface-mount package, supplier package size 29.31 × 29.31 mm, suitable for compact PCB layouts.
• Environmental & Grade — Military-grade device with an operating temperature range of −55 °C to 125 °C and RoHS compliance for regulatory compatibility.

Typical Applications

• Military & Aerospace Systems — Implements custom logic and I/O handling in environments requiring military-grade temperature and reliability.
• Embedded Control — Acts as a programmable control element for industrial controllers and ruggedized equipment needing flexible I/O and bespoke state machines.
• Sensor Interface & Conditioning — Aggregates and formats signals from multiple sensors using available I/O and logic resources for downstream processing.
• Protocol Bridging — Performs simple protocol conversion and interfacing tasks where a moderate number of logic elements and I/O are sufficient.

Unique Advantages

• Military-Grade Temperature Range: Rated for −55 °C to 125 °C, enabling deployment in harsh thermal environments with predictable behavior.
• Flexible Supply Voltage: 3 V to 5.5 V operation allows integration into systems with common legacy and modern power rails.
• Balanced Logic Density: 336 logic elements and ~14,000 gates provide a clear capacity for mid-range control and interface designs without unnecessary over-specification.
• Compact PLCC Footprint: The 84-lead PLCC (29.31 × 29.31 mm) offers a space-conscious package for PCB layouts that require through-board robustness and surface-mount assembly.
• RoHS Compliant: Meets RoHS requirements to assist with regulatory and manufacturing considerations.
