A54SX72A-2FGG484

Overview

The A54SX72A-2FGG484 is a Field Programmable Gate Array from the Microchip Technology SX-A family, utilizing antifuse technology. It features 6036 Configurable Logic Blocks (CLBs) and 108,000 system gates. The device supports up to 360 user-programmable I/O pins and includes 2,012 dedicated flip-flops. It operates with a maximum internal clock frequency of 350 MHz and a system performance of 250 MHz. The package is a 484-pin Fine Pitch Ball Grid Array (FBGA) with a 1.0 mm pitch. The speed grade '2' indicates approximately 25% faster performance than the standard speed grade.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing.
• Includes configurable weak-resistor pull-up or pull-down for I/O at power-up.
• Provides individual output slew rate control and deterministic user-controllable timing.

Applications

• High-performance logic integration replacing complex programmable logic devices.
• Systems requiring deterministic timing and fast counters or state machines.
• Applications needing nonvolatile single-chip solutions with secure programming.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, temperature grade, and lead-free status. Ensure compatibility with Actel Designer software versions for place-and-route tools. Check for end-of-life notifications as older speed grades may be discontinued.

Selection Notes

Select this device for designs requiring high gate density and fast internal clock frequencies up to 350 MHz. Consider the 484-pin FBGA package for applications needing a large number of I/Os. Verify that the required I/O standards match the supported 2.5 V, 3.3 V, and 5 V configurations.

Part Context

This component belongs to the SX-A family of FPGAs, which are fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers various capacity options ranging from 12,000 to 108,000 system gates. The A54SX72A represents the highest capacity in this specific series.

Replacement Considerations

Check for other speed grades within the A54SX72A series, such as -1 or -F, if performance requirements differ. Verify availability of alternative packages like the 256-pin FBGA if pin count allows reduction.
