A1280A-PG176M

Field Programmable Gate Array Overview

The A1280A-PG176M is a Field Programmable Gate Array (FPGA) belonging to the Microsemi ACT2 family. It features 8,000 equivalent system gates and comprises 1,232 Configurable Logic Blocks (CLBs). The device provides 140 user-accessible I/O pins and is housed in a 176-pin Ball Grid Array (BCPGA) package with dimensions of 39.88x39.88 mm. It operates on a single 5V supply voltage within a range of 4.5V to 5.5V. The component supports through-hole mounting and is rated for an industrial operating temperature range of 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• High-density logic architecture utilizing 1,232 CLBs for complex digital design implementation
• Robust I/O capability with 140 dedicated pins for extensive peripheral connectivity
• Standard 5V operation ensuring compatibility with legacy CMOS logic families

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic logic processing
• Legacy communication interface adapters
• Automotive embedded logic modules

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'M' against official Microsemi documentation, as standard listings often cite 'C' or 'I'. Confirm end-of-life status via recent Product Change Notices, as the ACT2 family has been discontinued. Ensure the supplier provides valid traceability for this obsolete component type.

Field Programmable Gate Array Selection Notes

Select this part when high gate density is required in a 176-lead BGA form factor. Compare against the A1280A-PG176C for commercial variants or A1280A-PG176I for extended temperature ranges. Consider the A1415 series if lower pin counts suffice.

Field Programmable Gate Array Part Context

This FPGA is part of the ACT2 family, representing a high-performance generation from Microsemi prior to its acquisition by Microchip Technology. The ACT2 series was designed to replace complex ASICs in mid-range applications, offering reprogrammability with performance comparable to fixed logic circuits of that era.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitutes are unavailable due to the discontinuation of the ACT2 family. Designers must evaluate modern Microchip PolarFire or SmartFusion2 FPGAs, which require significant architectural migration.
