A1425A-PL84C

Field Programmable Gate Array Overview

The A1425A-PL84C is an ACT3 Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features a logic capacity of 2,500 system gates and includes 310 LAB/CLB units. The device provides 69 I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in an 84-pin PLCC package with J-leads. The component supports surface mount installation and functions at ambient temperatures between 0°C and 70°C.

Field Programmable Gate Array Feature Summary

• ACT3 architecture providing embedded FPGA capabilities
• CMOS technology for low power consumption
• Supports standard ASIC design methodologies

Field Programmable Gate Array Applications

• General-purpose digital logic implementation
• Prototyping complex digital circuits
• Replacing fixed-function gate arrays

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PL84C' against official Microsemi documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as older ACT3 devices may not meet current environmental standards. Check for obsolescence notices or PCN documents from Microchip Technology, which acquired Microsemi, to assess long-term availability risks.

Field Programmable Gate Array Selection Notes

Compare the 2,500 gate count and 69 I/O limit against project requirements. Ensure the 84-PLCC package fits the PCB footprint constraints. Verify that the 4.5V to 5.5V operating voltage aligns with the target system's power rails. Consider the ACT3 series limitations regarding density compared to newer Microsemi families if future scalability is needed.

Field Programmable Gate Array Part Context

This part belongs to the ACT3 family of FPGAs, designed as a drop-in replacement for various PALs and GALs. It utilizes SRAM-based technology, requiring configuration data upon power-up. The ACT3 series was widely used for mid-density logic applications before being succeeded by higher-capacity devices.

Field Programmable Gate Array Replacement Considerations

Microsemi has transitioned under Microchip Technology. Consult Microchip datasheets for modern equivalents such as the SmartFusion or IGLOO families. Direct pin-compatible replacements are unlikely due to architectural differences; redesign may be necessary.
