A42MX09-3VQ100I

The A42MX09-3VQ100I from Microchip Technology is an industrial-grade MX family FPGA in a 100-TQFP package. It delivers mid-density programmable logic with 336 logic elements (approximately 14,000 gates) and 83 user I/O pins, making it suitable for control, interface, and glue-logic tasks where a compact, surface-mount FPGA is required.

Designed for systems that operate from 3 V to 5.5 V and across an industrial temperature range of −40 °C to 85 °C, the device supports robust integration into embedded designs that demand predictable logic resources and a small-footprint package.

Key Features

• Logic Resources  336 logic elements providing approximately 14,000 gates for implementing combinational and control logic.
• General-Purpose I/O  83 user I/O pins for interfacing to peripherals, sensors, and external devices.
• Package & Mounting  100-TQFP package (supplier device package: 100-VQFP, 14×14 mm) with surface-mount mounting for compact PCB layouts.
• Power Supply Range  Operates from 3 V to 5.5 V to accommodate a variety of system power rails.
• Industrial Temperature Grade  Rated for −40 °C to 85 °C operation for reliable performance in industrial environments.
• Environmental Compliance  RoHS-compliant construction to support regulatory and assembly requirements.

Typical Applications

• Industrial Control  Implement control logic and I/O arbitration in automation equipment using the device’s industrial temperature range and flexible supply voltages.
• Interface Bridging  Use the 83 I/O pins and mid-range logic capacity to bridge between microcontrollers, sensors, and legacy peripherals on compact PCBs.
• Embedded Glue Logic  Replace discrete glue components with programmable logic to consolidate functions and simplify BOMs in embedded designs.

Unique Advantages
