Overview of A3P400-FG256I – ProASIC3 FPGA, 400,000 gates, 256-LBGA
The A3P400-FG256I is a ProASIC3 field programmable gate array (FPGA) in a 256-LBGA package designed for industrial-grade applications. It provides 9,216 logic elements and approximately 0.055 Mbits of embedded memory, together with up to 178 I/O pins for implementing reconfigurable system logic.
With a defined core supply range of 1.425 V to 1.575 V and an operating temperature range of −40 °C to 100 °C, this device targets designs that require a compact, surface-mount FPGA offering substantial logic capacity and flexible I/O in a 17 mm × 17 mm FPBGA footprint.
Key Features
- Core Logic 9,216 logic elements (cells) providing the programmable fabric to implement custom digital functions and state machines.
- Logic Capacity Approximately 400,000 gates to support medium-complexity logic and control implementations.
- Embedded Memory 55,296 total RAM bits (approximately 0.055 Mbits) for on-chip data buffering, FIFOs, and small lookup tables.
- I/O Count 178 general-purpose I/O pins to connect peripherals, buses, and external devices directly to the FPGA fabric.
- Power Core voltage supply specified from 1.425 V to 1.575 V for deterministic power planning and regulator selection.
- Package and Mounting 256-LBGA (supplier device package: 256-FPBGA, 17×17) in a surface-mount form factor suitable for compact PCB layouts.
- Industrial Grade and Temperature Rated for industrial operation with an operating temperature range of −40 °C to 100 °C.
