A54SX32A-1FGG144I

Overview

The A54SX32A-1FGG144I is an SX-A family Field Programmable Gate Array featuring antifuse technology. It provides 48,000 system gates and 2,880 logic modules within a 144-pin Fine Pitch Ball Grid Array package. The device supports up to 111 user-programmable I/O pins and operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. It utilizes a 0.22 μm / 0.25 μm CMOS process and requires a 2.5 V core voltage. The Industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Supports hot-swap capabilities for safe insertion into active systems without power sequencing requirements.
• Includes IEEE 1149.1 compliant boundary-scan testing for enhanced diagnostic and verification.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering.
• Enables deterministic timing through user-controllable clock resources and routing.

Applications

• High-speed data path logic and fast counters
• State machine implementations requiring predictable timing
• PCI-compliant interface designs

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature range requirement. Confirm the 'G' suffix indicates RoHS compliance if environmental standards are mandatory. Ensure the design tool version supports the SX-A architecture for proper configuration.

Selection Notes

Select this component when 48,000 system gates and 111 I/Os fit the design constraints. The -1 speed grade offers approximately 15% faster performance than standard grades. Verify that the 144-pin FBGA package dimensions match the PCB layout requirements.

Part Context

This part belongs to the Microsemi (formerly Actel) SX-A family of nonvolatile FPGAs. It shares architectural features with other SX-A devices like the A54SX32A-FGG144 but differs in speed grade and temperature rating. The antifuse technology distinguishes it from volatile SRAM-based FPGAs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed using the official Microchip compatibility matrix or by consulting authorized distributors for equivalent capacity and package options.

FAQ

What is the difference between the -1 speed grade and the standard grade?

The -1 speed grade provides approximately 15% faster performance compared to the standard speed grade.

How does the device handle unused JTAG pins?

In Flexible mode, TDI, TCK, and DDO can function as user I/Os. In Dedicated mode, they are reserved for BST. Unused pins must not be left floating.

Is the A54SX32A-1FGG144I hot-swappable?

Yes, the I/Os are configured to be hot-swappable, except for 3.3 V PCI configurations.
