A40MX04-VQ80M

The A40MX04-VQ80M is an MX-series Field Programmable Gate Array (FPGA) from Microchip Technology that provides a compact, reprogrammable logic fabric for embedded designs. It integrates approximately 6000 gates and 547 logic elements with 69 user I/O pins in an 80-TQFP surface-mount package.

Designed for applications requiring rugged operating conditions, the device is specified as military grade with an operating temperature range of -55 °C to 125 °C and a wide supply range of 3 V to 5.5 V, making it suitable for designs that must withstand harsh environments and varied power rails.

Key Features

• Logic Capacity — 547 logic elements (CLBs) and approximately 6000 gates provide reprogrammable logic resources for custom control and interfacing functions.
• Input/Output — 69 user I/O pins available for direct interfacing to peripherals, sensors, and external logic.
• Power Supply — Operates from 3 V to 5.5 V, supporting a broad range of board-level power architectures.
• Package & Mounting — 80-TQFP package; supplier device package listed as 80-VQFP (14 × 14 mm) in a surface-mount form factor for PCB assembly.
• Temperature & Grade — Military grade device specified for operation from -55 °C to 125 °C for use in demanding thermal environments.
• On‑Chip Memory — Total on-chip RAM: 0 bits; logic resources are provided as CLBs rather than embedded RAM blocks.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Military and Aerospace Electronics — Military-grade temperature range and rugged electrical tolerances make the FPGA suitable for avionics, communication modules, and mission-critical control electronics.
• Embedded Control and Signal Glue Logic — Use the device to implement custom control state machines, protocol bridging, and signal conditioning where dedicated ASICs are not required.
• Sensor and Peripheral Interfacing — 69 I/O pins allow flexible connection to sensors, ADC/DAC front ends, and external processors for deterministic, hardware-level interfacing.
• Industrial Automation — Reprogrammable logic enables custom I/O handling and timing functions in automation controllers that operate across a wide temperature and voltage range.

Unique Advantages

• Compact, Reprogrammable Logic: 547 logic elements and ~6000 gates provide a dense, reconfigurable implementation option without committing to an ASIC.
• Wide Supply Range: 3 V to 5.5 V support simplifies integration into systems with multiple supply domains or legacy logic levels.
• High I/O Count in a Small Package: 69 user I/Os in an 80-TQFP package let you maximize signal connectivity while maintaining a compact PCB footprint.
• Rugged Operating Envelope: Military-grade temperature qualification (-55 °C to 125 °C) supports deployment in harsh thermal environments.
• Surface-Mount, Industry-Standard Package: 80-VQFP (14 × 14 mm) supplier package enables standard PCB assembly and rework processes.
• RoHS Compliant: Conforms to environmental regulations for lead-free assembly and disposal considerations.
