A42MX16-PLG84M

The Microchip Technology A42MX16-PLG84M is a military-grade, antifuse-based field-programmable gate array (FPGA) from the MX family, delivering non-volatile, single-chip logic integration in an 84-lead PLCC package. This device provides approximately 16,000 system gates of user-programmable logic with a 5‑V operating voltage and typical pin-to-pin delays as low as 4.4 ns. As an antifuse FPGA, it stores configuration permanently on-chip, eliminating the need for external boot memory and offering inherent protection against unauthorized design cloning or bit‑stream tampering. The one-time-programmable architecture also enables instant‑on operation without configuration latency, while the PLCC package provides robust through‑hole or surface‑mount attachment suited to high‑reliability board designs.

Typical applications include military avionics, missile guidance and control systems, secure communications platforms, and high‑temperature industrial embedded controllers where deterministic start‑up behavior, radiation tolerance, and long‑term operational stability are critical. The MX family’s proven antifuse technology is frequently deployed in system‑critical glue logic, bus interface bridging, and sequencing functions under harsh environmental conditions. Procurement professionals should note that the ‘M’ suffix indicates a military temperature range of –55 °C to +125 °C, qualifying the device for defense and aerospace programs that demand extended operational margins. The MX series is a mature product line; while Microchip maintains long‑term support for this HiRel segment, design teams are advised to assess obsolescence timelines and secure appropriate lifetime‑buy inventory or last‑time‑buy planning in coordination with authorized distribution to ensure long‑term program sustainment.
