A42MX16-3PQG100I

The A42MX16-3PQG100I is an MX series field programmable gate array (FPGA) from Microchip Technology, offered in a 100-pin BQFP package. It delivers a low- to mid-density programmable logic solution with 608 logic elements (approximately 24,000 gates) and 83 general-purpose I/O pins for flexible on-board logic integration.

Designed for industrial environments, this surface-mount FPGA supports a 3 V to 5.5 V supply range and an operating temperature span of −40° C to 85° C, providing predictable behavior across a wide range of embedded and control applications.

Key Features

• Core Logic — 608 logic elements and 24,000 gates provide the capacity for implementing custom combinational and sequential logic functions.
• I/O — 83 general-purpose I/O pins enable connectivity to peripherals, sensors, and external logic devices.
• On-Chip Memory — Total RAM Bits: 0 (no embedded RAM), suitable for designs that rely on external memory or are primarily combinational/logic-centric.
• Power — Operates from 3 V to 5.5 V, supporting a broad range of supply schemes common in industrial and embedded systems.
• Package & Mounting — 100-BQFP package case; supplier device package listed as 100-PQFP (20×14). Surface-mount mounting type for board-level integration.
• Environmental & Grade — Industrial grade with an operating temperature range of −40° C to 85° C and RoHS compliance for regulatory alignment.

Typical Applications

• Industrial Automation — Implement custom control logic and signal routing in industrial controllers where an industrial temperature range is required.
• Embedded System Glue Logic — Replace discrete logic or implement interface translation and timing control using the device’s logic resources and abundant I/O.
• I/O Management — Aggregate and manage multiple peripheral signals or implement custom I/O protocols across the 83 available pins.
• Low- to Mid-Density Logic Integration — Integrate finite-state machines, simple datapaths, and control logic within a compact surface-mount package.

Unique Advantages

• Industrial Temperature Rating: −40° C to 85° C specification supports deployment in temperature-sensitive industrial systems.
• Wide Supply Range: 3 V to 5.5 V operation accommodates a variety of board-level power architectures.
• Balanced Logic Capacity: 608 logic elements and 24,000 gates provide predictable resources for small to medium custom logic designs.
• Compact Surface-Mount Package: 100-BQFP (supplier 100-PQFP 20×14) offers a space-efficient form factor for populated PCBs.
• Regulatory Compliance: RoHS compliant for adherence to environmental and manufacturing requirements.
