A42MX09-2PQ100I

The A42MX09-2PQ100I is an MX Field Programmable Gate Array (FPGA) IC from Microchip Technology designed to provide compact programmable logic for embedded designs. It delivers a defined set of logic resources and a high I/O count in a 100‑pin surface-mount package suitable for industrial applications.

With 336 logic elements (approximately 14,000 gates), 83 user I/O pins, a 3.0 V to 5.5 V supply range and an industrial operating temperature of −40 °C to 85 °C, this device is targeted at applications that require modest programmable logic capacity combined with robust environmental tolerance.

Key Features

• Core logic — 336 logic elements providing a predictable capacity of roughly 14,000 gates for combinational and sequential logic implementation.
• I/O density — 83 user I/O pins to interface with peripherals, sensors, and external devices.
• On‑chip memory — Total RAM bits: 0, reflecting a device optimized for logic-centric functions without embedded RAM.
• Supply voltage — Operates from 3 V to 5.5 V, enabling flexible interfacing across multiple logic-voltage domains.
• Package and mounting — Surface-mount 100‑BQFP package; supplier device package referenced as 100‑PQFP (20×14) for PCB footprint considerations.
• Temperature rating — Industrial operating range from −40 °C to 85 °C for use in harsh environments.
• Environmental compliance — RoHS compliant for environmental regulatory requirements.

Typical Applications

• Industrial control and automation — Use the device’s industrial temperature rating and plentiful I/O to implement machine control logic, sensor interfacing, and discrete I/O handling.
• Interface bridging and glue logic — Programmable logic and 83 I/Os are suited to protocol conversion, bus interfacing, and custom signal routing between subsystems.
• Embedded system prototyping — Compact package and defined logic resources make the device useful for evaluating and validating small-scale programmable logic designs.
• Peripheral and I/O management — Implement control of displays, keypads, LED drivers, and other front-panel or board-level peripheral functions.

Unique Advantages

• Compact, high-density package: 100‑pin BQFP / 100‑PQFP (20×14) provides a small PCB footprint while delivering substantial I/O capacity.
• Flexible voltage operation: 3.0 V to 5.5 V supply range simplifies interfacing across different logic voltage domains without additional level-shifting components in many cases.
• Industrial temperature range: −40 °C to 85 °C supports deployment in demanding environments and extended-temperature applications.
• Clearly defined logic resources: 336 logic elements and approximately 14,000 gates give designers a predictable implementation target for small- to medium-complexity logic functions.
• Regulatory readiness: RoHS compliance supports environmentally conscious product development and procurement.
