A42MX16-3PQG208I

The A42MX16-3PQG208I is a Microchip Technology MX-series field programmable gate array (FPGA) supplied in a 208-BFQFP (208-PQFP, 28×28) surface-mount package. It delivers moderate logic capacity with 608 logic elements (approximately 24,000 gates) and a dense I/O count for embedded and industrial designs.

Designed for industrial environments, the device supports a wide supply range (3 V to 5.5 V) and an operating temperature range of −40 °C to 85 °C, making it suitable for deployed systems that require robust electrical and thermal tolerance.

Key Features

• Logic Capacity — 608 logic elements and approximately 24,000 gates provide deterministic combinational and sequential logic resources for glue logic, control functions, and moderate-density custom logic implementation.
• I/O Density — 140 user I/O pins enable extensive interfacing to peripherals, sensors, and external devices without large external glue circuitry.
• Voltage Flexibility — Operates across a 3 V to 5.5 V supply range to support a variety of legacy and modern I/O voltage domains.
• Package and Mounting — 208-BFQFP (supplier package: 208-PQFP, 28×28) in a surface-mount form factor for compact PCB layouts and standard SMT assembly.
• Industrial Temperature Rating — Rated for −40 °C to 85 °C operation to meet industrial deployment and environmental tolerance requirements.
• Compliance — RoHS compliant to support regulatory environmental requirements for electronic assemblies.
• On-Chip Memory — Total on-chip RAM: 0 bits, enabling applications that rely on external memory or are optimized for minimal embedded RAM usage.

Typical Applications

• Industrial Control & Automation — Leverages the industrial temperature rating and wide supply range for control logic, I/O aggregation, and protocol bridging in factory and process automation equipment.
• Embedded Systems — Provides moderate logic resources and 140 I/O for custom interfaces, state machines, and peripheral control in embedded platforms.
• I/O Expansion and Glue Logic — Useful for consolidating discrete logic, translating voltage domains, and simplifying boards with high I/O counts.
• Instrumentation and Test Equipment — Fits designs that require deterministic logic, multiple external interfaces, and industrial-grade operating temperatures.

Unique Advantages

• Balanced Logic Density: 608 logic elements with ~24,000 gates give designers predictable capacity for moderate-complexity custom logic without excessive device overhead.
• High I/O Count: 140 I/O pins reduce the need for additional interface chips and simplify routing for multi-signal applications.
• Wide Supply Range: 3 V to 5.5 V operation supports mixed-voltage systems and eases integration with legacy peripherals.
• Industrial Robustness: −40 °C to 85 °C rating and industrial grade designation support deployment in demanding environments.
• Standard SMT Package: 208-BFQFP (28×28) surface-mount package enables compact board designs and compatibility with common PCB assembly processes.
• RoHS Compliant: Environmental compliance helps meet regulatory requirements for electronic products.
