A1010B-2PLG44I

Field Programmable Gate Array Overview

The A1010B-2PLG44I is a Field Programmable Gate Array from the ACT 1 Series, manufactured by Microsemi Corporation. It features 295 logic modules and 1200 gate array equivalent gates. The device utilizes PLICE antifuse technology for nonvolatile user programming. It operates within an industrial temperature range of -40°C to +85°C and supports a maximum data rate of 75 MHz at 5V. The component is housed in a 44-pin Plastic J-Leaded Chip Carrier package with 34 user I/Os.

Field Programmable Gate Array Feature Summary

• Employs PLICE antifuse technology for instant turnaround and nonvolatile configuration.
• Features two independent diagnostic probe pins for real-time signal observation during debugging.
• Includes a built-in high-speed clock distribution network with hardwired routing for minimum skew.
• Supports automatic place and route design implementation via Designer systems.

Field Programmable Gate Array Applications

• System logic replacement for TTL and PAL packages
• Image compression algorithm implementation
• Data processing units in spaceborne payloads

Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature rating (-40°C to +85°C) as defined in the ACT 1 datasheet. Confirm the package type matches the 44-pin plastic leaded chip carrier specification. Check for current availability status as older Actel/Microsemi components may be discontinued or subject to last-time buys.

Field Programmable Gate Array Selection Notes

Select this model when 295 logic modules are sufficient for the design complexity. Ensure the application requires the industrial temperature grade rather than commercial or military options. Verify that the 44-pin package footprint fits the PCB layout constraints compared to other available pin counts like 68 or 84.

Field Programmable Gate Array Part Context

This component belongs to the ACT 1 family of FPGAs, which uses 1.0 micron CMOS technology. The family includes variants like A1020B with higher capacity. The 'A1010' designation indicates the 1200-gate density level within the series.

Field Programmable Gate Array Replacement Considerations

Direct replacements include other ACT 1 devices such as A1010B-1PLG44I or A1010B-3PLG44I for different speed grades. Cross-family migration to Microsemi SmartFusion or IGLOO may require significant architectural redesign.

Field Programmable Gate Array FAQ

What is the function of the MODE pin?

The MODE pin controls multifunction pins (DCLK, PRA, PRB, SDI). When HIGH, special functions are active; when LOW, they function as standard I/O.

How does the ACT 1 architecture handle timing predictability?

It offers tight fanout delay distributions by limiting interconnect paths to a maximum of four antifuses, ensuring predictable performance through automatic place and route.

Can the diagnostic probe pins be used as regular I/O?

Yes, the Probe A and Probe B pins can function as user-defined I/Os once debugging is completed.
