A42MX24-PL84M

The A42MX24-PL84M is an MX family field programmable gate array (FPGA) from Microchip Technology in an 84-lead LCC (J-lead) package. It provides on-board programmable logic suitable for military-grade applications, offering a balance of moderate logic capacity and robust environmental tolerance.

Designed as a surface-mount PLCC solution, this device targets board-level digital designs that require a programmable logic element with 72 I/O pins, broad supply-voltage compatibility, and extended temperature operation.

Key Features

• Core Logic — 912 logic element cells and approximately 36,000 gates provide capacity for moderately complex custom digital functions.
• I/O Count — 72 general-purpose I/O pins to support multiple peripheral interfaces and system signals without external expansion.
• Voltage Supply — Operates across a wide 3 V to 5.5 V supply range for flexible power-rail integration.
• Package & Mounting — 84-LCC (J-Lead) surface-mount package; supplier device package specified as 84-PLCC with dimensions 29.31 × 29.31 mm for straightforward board-level integration.
• Temperature & Grade — Military grade device rated for operation from -55 °C to 125 °C to meet harsh-environment requirements.
• Regulatory — RoHS compliant to support lead-free assembly processes.

Typical Applications

• Military electronics — Board-level programmable logic for systems requiring military-grade temperature performance and reliability.
• Embedded control systems — Implement custom digital control and I/O handling using the device's logic capacity and 72 I/Os.
• PLCC footprint integrations — Drop-in integration into designs or replacements that use an 84-PLCC (29.31 × 29.31 mm) package footprint.

Unique Advantages

• Military-grade environmental tolerance: Rated from -55 °C to 125 °C to support designs that must withstand extreme temperatures.
• Flexible power compatibility: 3 V to 5.5 V supply range simplifies use across different system power architectures.
• Balanced logic density: 912 logic elements and ~36,000 gates enable implementation of a wide range of custom digital functions without excessive board-level complexity.
• Ample I/O resources: 72 I/O pins reduce the need for external GPIO expanders and simplify interfacing to sensors, actuators, and peripherals.
• Standard PLCC surface-mount package: 84-LCC (J-Lead) and 84-PLCC package dimensions allow integration into established board designs and form factors.
• RoHS compliant: Aligns with lead-free assembly and environmental requirements.
