A3P125-TQG144I

The A3P125-TQG144I is a ProASIC3 field programmable gate array from Microchip Technology. It provides 3,072 logic elements and 36,864 bits of on-chip RAM in a 144-pin LQFP surface-mount package, with a supply voltage range of 1.425 V to 1.575 V and an industrial operating temperature range of -40 °C to 100 °C.

This device is suited to applications that require configurable digital logic, a moderate I/O count and embedded RAM while meeting industrial temperature and RoHS compliance requirements.

Key Features

• Core Logic — 3,072 logic elements (reported as number of LABs/CLBs) and 125,000 gates provide the programmable logic capacity for custom digital designs.
• On-chip Memory — 36,864 bits of total RAM bits available for implementing embedded memory structures and state machines.
• I/O Count — 100 user I/Os to interface with peripherals, sensors and external logic.
• Package & Mounting — 144-LQFP surface-mount package (supplier device package: 144-TQFP, 20×20) for compact PCB assembly.
• Power — Low-voltage single-supply operation with a specified supply range of 1.425 V to 1.575 V.
• Industrial Temperature Grade — Rated for operation from -40 °C to 100 °C and marked as industrial grade for temperature-demanding environments.
• RoHS Compliant — Meets RoHS environmental requirements for restricted substances.

Unique Advantages

• Balanced Logic and Memory: Combines 3,072 logic elements with 36,864 bits of RAM to support both combinational and stateful logic within a single device, reducing the need for external memory in many designs.
• Generous I/O Count: 100 I/Os provide flexibility for interfacing multiple peripherals or parallel data paths without additional I/O expanders.
• Industrial Temperature Range: Rated from -40 °C to 100 °C, enabling deployment in temperature-sensitive industrial environments.
• Compact Surface-Mount Package: 144-LQFP (144-TQFP 20×20) packaging supports dense PCB layouts and standard surface-mount assembly processes.
• Controlled Supply Window: Narrow supply voltage range (1.425 V–1.575 V) allows precise power budgeting and predictable device behavior when designed to the specified rails.
• Regulatory Compliance: RoHS compliance supports regulatory and sustainability requirements for electronic assemblies.
