A1225A-1PLG84I

Field Programmable Gate Array Overview

The A1225A-1PLG84I is a high-performance Field Programmable Gate Array (FPGA) from Microsemi's ProASIC3 family, housed in an 84-pin Plastic Low-profile Quad Flat Package (PLQFP). It features 1225 system gates and supports up to 60 I/O pins. The device integrates 192 Kbits of embedded Flash memory for non-volatile configuration storage. Key electrical specifications include a maximum operating frequency of 200 MHz at the -1 speed grade and a supply voltage range of 1.14V to 1.26V for core logic. It operates within an industrial temperature range of -40°C to +85°C, ensuring reliability in demanding environments.

Field Programmable Gate Array Feature Summary

• Non-volatile Flash-based architecture eliminates the need for external configuration memory devices.
• Supports rapid prototyping and field-upgradable designs through in-system reprogrammability.
• Integrates dedicated hardware blocks for serial communication protocols such as SPI and I2C.

Field Programmable Gate Array Applications

• Industrial control systems requiring robust FPGA solutions.
• Automotive electronics applications with strict environmental constraints.
• Telecommunications infrastructure equipment needing reliable signal processing.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix codes on the component marking against official Microsemi documentation to confirm temperature grade and package variant. Ensure that the procurement channel provides traceability certificates matching the part number A1225A-1PLG84I. Cross-reference the date code and lot information with manufacturer records to validate authenticity and avoid counterfeit components during acquisition.

Field Programmable Gate Array Selection Notes

Select this model when a compact PLQFP package is required alongside moderate logic density. Compare the 192 Kbit Flash capacity against application requirements to determine if additional external memory is necessary. Evaluate the -1 speed grade performance against timing constraints to ensure the 200 MHz limit meets system clock requirements without compromising signal integrity.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ProASIC3 family, designed for cost-sensitive applications requiring low power consumption and small form factors. It serves as a bridge between complex ASICs and standard CPLDs, offering higher density than traditional programmable logic while maintaining ease of use. The PLG84 package provides a balance between pin count and board space efficiency for mid-range logic applications.

Field Programmable Gate Array Replacement Considerations

Direct replacements are limited due to proprietary Flash technology. Consider the A1225A-1FGG484I for BGA package variants or the A1225A-1VQG100I for QFN packages if pin compatibility allows. Verify that any substitute maintains the same gate count and Flash capacity to ensure functional equivalence in existing designs.
