A54SX32A-2TQG100

Overview

The A54SX32A-2TQG100 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 81 user-programmable I/Os. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to provide deterministic timing with up to 100% resource utilization and pin locking. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swap capabilities for simplified power sequencing without supply voltage requirements.
• Provides IEEE 1149.1 compliant boundary-scan testing via JTAG interface.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering.
• Features configurable weak-resistor pull-up or pull-down for I/O states during power-up.

Applications

• 66 MHz PCI compliant designs
• Low-power high-performance logic integration
• Systems requiring deterministic timing and pin locking

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the '2' speed grade indicates approximately 25% faster performance than standard. Ensure the TQFP package type matches the design footprint. Check for RoHS compliance status if required by assembly specifications.

Selection Notes

Select this model for applications requiring 48K system gates with industrial temperature stability. The -2 speed grade offers higher frequency performance compared to standard grades. Verify that the 100-pin TQFP package fits the PCB constraints. Consider the 5V tolerant I/Os if interfacing with legacy components.

Part Context

This component belongs to the Microchip (formerly Actel) SX-A FPGA family, which uses nonvolatile antifuse technology. The A54SX32A variant provides 48,000 system gates, positioning it between the smaller A54SX16A and larger A54SX72A devices in terms of capacity and I/O availability.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation.

FAQ

What is the maximum internal clock frequency supported by the SX-A family?

The SX-A family supports internal clock frequencies up to 350 MHz.

How does the DirectConnect feature improve performance?

DirectConnect provides a hardwired signal path between a C-cell and its neighboring R-cell within a SuperCluster, achieving a maximum routing delay of less than 0.1 ns without using programmable antifuses.

Can unused JTAG pins be used as general I/O?

Yes, in Flexible mode, TDI, TCK, and TDO may function as user I/Os or BST pins, while TMS cannot be employed as a user I/O in either mode.
