A42MX36-1CQ256M

The A42MX36-1CQ256M is an MX series field programmable gate array (FPGA) from Microchip Technology, designed for mid-density logic integration and flexible I/O interfacing. This surface-mount FPGA combines 1,184 logic elements, approximately 2.5 kbits of embedded RAM, and 202 general-purpose I/O pins to support compact, system-level digital designs.

With a wide supply voltage range of 3 V to 5.5 V and a military-grade operating temperature range of −55 °C to 125 °C, this device is intended for applications that require robust operation across extreme environmental conditions while consolidating logic and I/O functions into a single programmable component.

Key Features

• Core Logic  1,184 logic elements provide mid-density programmable logic suitable for glue logic, protocol bridging, and custom state machines.
• Logic Capacity  Approximately 54,000 equivalent gates to map a range of discrete and integrated logic functions.
• Embedded Memory  Approximately 2.5 kbits of on-chip RAM for small buffering, FIFOs, or register storage within user logic.
• I/O Density  202 user I/O pins enable extensive peripheral interfacing and signal routing without external I/O expanders.
• Power  Wide operating voltage range from 3 V to 5.5 V for compatibility with multiple system power domains.
• Package  256-BFCQFP with tie bar; supplier device package listed as 256-CQFP (75×75) in a surface-mount format for PCB assembly.
• Temperature and Grade  Military grade device rated for −55 °C to 125 °C for deployment in harsh and mission-critical environments.
• Compliance  RoHS compliant for adherence to restricted substance regulations.

Typical Applications

• Military and Defense Electronics  Suitable for embedded control and interface logic in systems that must operate across −55 °C to 125 °C.
• I/O-Intensive Systems  High pin count supports sensor networks, communication interfaces, and board-level signal aggregation without extensive external glue logic.
• Mid-Density Logic Integration  Consolidates discrete logic functions and simple state machines using 1,184 logic elements and ~54,000 equivalent gates.
• Rugged Embedded Control  Ideal for control and monitoring tasks in environments requiring wide voltage tolerance (3 V–5.5 V) and military-grade reliability.
