The A3PN125-1VQG100 is a ProASIC3 nano field programmable gate array (FPGA) from Microchip Technology presented in a 100-pin TQFP package. It delivers a mid-range programmable logic resource set with 3,072 logic elements, approximately 125,000 gates and 36,864 bits of on-chip RAM for compact, low-voltage FPGA implementations.

Designed as a commercial-grade, surface-mount device, this part provides 71 I/Os and operates from 1.425 V to 1.575 V over a temperature range of -20 °C to 85 °C, making it suitable for a variety of standard embedded and electronic designs that require programmable logic and on-chip memory.

Key Features

• Core Logic  3,072 logic elements (LEs) delivering approximately 125,000 gates of programmable logic capacity for mid-density designs.
• Embedded Memory  36,864 bits of on-chip RAM to support buffering, small lookup tables and state storage within the FPGA fabric.
• I/O Count  71 user I/Os to interface with system peripherals, sensors, and external devices.
• Power Supply  Single-supply operation in the range 1.425 V to 1.575 V to match low-voltage system rails.
• Package and Mounting  100-TQFP surface-mount package; supplier device package listed as 100-VQFP (14 × 14 mm) for footprint reference.
• Temperature and Grade  Commercial-grade device rated for -20 °C to 85 °C ambient operation.
• Regulatory Compliance  RoHS compliant for lead-free assembly and regulatory alignment in commercial products.

Typical Applications

• Embedded Control  Use where moderate programmable logic and on-chip RAM are needed to implement control functions with up to 71 external signals.
• Interface and Glue Logic  Suitable for bridging or protocol adaptation tasks that require flexible pin count and mid-range logic capacity.
• Prototyping and Development  Fits board-level prototypes that need a surface-mount FPGA in a compact 100-pin TQFP footprint.

Unique Advantages

• Balanced Logic Density:  3,072 logic elements and 125,000 gates provide a clear mid-density option for designs that exceed simple CPLD capabilities but do not require high-end FPGAs.
• On-Chip RAM:  36,864 bits of embedded memory reduce the need for external RAM for small buffers and state tables, simplifying BOM and board layout.
• Ample I/O Count:  71 I/Os enable connections to multiple peripherals, sensors, or buses without immediate need for I/O expanders.
• Compact, Surface-Mount Package:  100-TQFP (100-VQFP 14×14 mm reference) allows integration into space-constrained PCBs while maintaining a reasonable pin count.
• Commercial Temperature Range:  Rated for -20 °C to 85 °C to support typical commercial embedded applications.
• RoHS Compliant:  Conforms to lead-free manufacturing requirements for commercial products.
