A3P1000-1FG144I

Field Programmable Gate Array Overview

The A3P1000-1FG144I is a ProASIC3 FPGA from Microchip Technology, featuring 1 million system gates and 24,576 configurable logic blocks. It operates within a supply voltage range of 1.425 V to 1.575 V at a nominal 1.5 V. The device supports up to 97 user I/Os and achieves a maximum operating frequency of 350 MHz. It utilizes a 144-pin FBGA package with a 1 mm pitch. The industrial temperature grade ensures reliable operation between -40°C and +85°C.

Field Programmable Gate Array Feature Summary

• Flash-based non-volatile architecture enabling live-at-power-up functionality without external configuration memory.
• Supports mixed-voltage I/O standards including LVCMOS, LVTTL, LVDS, and PCI/PCI-X for flexible interface integration.
• Integrated Clock Conditioning Circuits (CCC) and Phase-Locked Loops (PLL) for precise clock management.

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic boot times.
• Communication infrastructure utilizing high-speed differential signaling.
• Automotive electronics operating in extended temperature environments.

Field Programmable Gate Array Procurement Notes

Verify the suffix 'I' confirms the industrial temperature rating (-40°C to +85°C). Confirm the '-1' speed grade matches the required 350 MHz performance target. Ensure the FG144 package footprint aligns with the PCB layout specifications before ordering.

Field Programmable Gate Array Selection Notes

Select this component when non-volatile flash technology is preferred over SRAM-based FPGAs to eliminate external configuration chips. Compare against the A3P1000-FG144 variant if commercial temperature grades suffice. Evaluate the 144-pin constraint against total I/O requirements to ensure adequate pin count for the design.

Field Programmable Gate Array Part Context

This part belongs to the ProASIC3 family, representing a mid-range density solution within Microchip's flash FPGA portfolio. It bridges the gap between low-density devices like the A3P250 and higher-capacity options, offering a balance of gate count and power efficiency for complex logic applications.

Field Programmable Gate Array Replacement Considerations

The M1A3P1000-1FG144I serves as a direct functional replacement, adding an embedded ARM Cortex-M1 processor. Verify that the additional processing resources do not impact power or thermal budgets compared to the standard A3P1000 variant.
