A42MX16-1VQG100I

The A42MX16-1VQG100I is a field programmable gate array (FPGA) offered by Microchip Technology in a 100‑pin TQFP package. It provides a mid-range, industrial‑grade programmable logic resource with a mix of logic density, I/O capacity and wide supply and temperature tolerances suited for embedded and industrial applications.

With 608 logic elements (approximately 24,000 gates), 83 general-purpose I/Os, support for 3 V to 5.5 V supply rails and an operating temperature range of −40 °C to 85 °C, the device enables custom digital functions, I/O interfacing and protocol bridging in compact surface-mount form factors.

Key Features

• Programmable logic fabric — 1232 CLBs and 608 logic elements providing approximately 24,000 gates for implementing custom digital functions and glue logic.
• I/O capacity — 83 general-purpose I/O pins to support multiple peripheral interfaces and external device control in a single package.
• Power flexibility — Operates from 3 V to 5.5 V supply rails, allowing integration with a range of legacy and modern system voltages.
• Package and mounting — 100‑TQFP surface-mount package (supplier package: 100‑VQFP, 14×14) for compact board layouts and standard assembly processes.
• Industrial temperature range — Specified for −40 °C to 85 °C operation to meet many industrial and embedded environmental requirements.
• No on-chip RAM — The device reports 0 total RAM bits; system architects can plan external memory or logic-based alternatives accordingly.
• Regulatory status — RoHS compliant to facilitate lead‑free assembly and regulatory alignment.

Typical Applications

• Industrial control and automation — Implement custom I/O handling, deterministic logic and protocol conversion within industrial equipment operating across a wide temperature range.
• Embedded system glue logic — Replace discrete logic with programmable functions to consolidate boards and reduce bill of materials for mid-density logic requirements.
• Custom interface bridging — Create protocol adapters or bus translators where flexible I/O mapping and moderate logic density are required.
• User interface and peripheral control — Manage button/LED scanning, keypad interfaces and peripheral sequencing using onboard programmable logic and available I/Os.

Unique Advantages

• Industrial-grade specification: Rated for −40 °C to 85 °C operation, supporting reliable deployment in industrial and embedded environments.
• Wide supply compatibility: 3 V to 5.5 V operating range simplifies integration into systems with varied legacy or modern voltage domains.
• Balanced logic and I/O density: Approximately 24,000 gates with 608 logic elements and 83 I/Os provides sufficient capacity for mid-range programmable tasks while keeping board footprint small.
• Compact surface-mount package: 100‑TQFP (14×14) enables dense PCB layouts and standard assembly processes for volume production.
• RoHS compliant: Facilitates lead‑free assembly and adherence to environmental regulations.
