A40MX04-1PLG44M

The A40MX04-1PLG44M is an MX-series Field Programmable Gate Array (FPGA) from Microchip Technology designed for board-level integration where a compact, military-grade programmable logic device is required. It provides moderate logic capacity and a configurable I/O count in a 44-LCC (J-lead) surface-mount package, supporting a wide supply range and extended operating temperatures.

This device targets applications that require up to 34 I/O lines, approximately 547 logic elements and 6,000 gates, combined with a broad 3 V to 5.5 V supply window and a military operating temperature rating for reliable performance in demanding environments.

Key Features

• Core and Logic Approximately 547 logic elements and 6,000 gates provide the programmable fabric for glue logic, small state machines, and custom peripheral interfacing.
• I/O 34 user I/O pins allow flexible interfacing with external devices and peripherals at the board level.
• Power Wide supply voltage range from 3 V to 5.5 V supports a variety of legacy and modern power domains.
• Package and Mounting 44-LCC (J-lead) / 44-PLCC (16.59 × 16.59 mm) surface-mount package suited for designs that require a PLCC footprint with J-lead soldering.
• Temperature and Grade Military grade with an operating temperature range of −55 °C to 125 °C for deployment in high-reliability and harsh-temperature environments.
• Compliance RoHS compliant to meet environmental and manufacturing requirements.

Typical Applications

• Military and Aerospace Systems — Suitable for board-level programmable logic tasks in designs that require military-grade temperature range and reliability.
• Rugged Communications Equipment — Provides configurable I/O and logic resources for protocol bridging and custom packet handling in harsh environments.
• Legacy Board Upgrades and Repairs — 44-PLCC-compatible package and J-lead mounting make the device a practical choice for replacements or refurbishments of PLCC-based designs.
• Embedded Control and I/O Interfacing — Moderate logic density and 34 I/O pins support glue logic, sensor interfacing, and peripheral control on compact boards.
