A54SX16A-2PQG208

Overview

The A54SX16A-2PQG208 is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 24,000 system gates and housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It supports up to 175 user-programmable I/O pins and operates with a standard supply voltage of 2.5 V, accommodating a range between 2.25 V and 2.75 V. The device delivers a maximum system performance frequency of 250 MHz and an internal clock speed of 350 MHz. Designed for commercial applications, it functions within a temperature range of 0°C to +70°C.

Feature Summary

• Utilizes nonvolatile antifuse technology for permanent configuration without external memory.
• Supports mixed-voltage I/O standards including 5V TTL, 3.3V PCI, and 2.5V LVCMOS2.
• Features hot-swap compliant I/Os allowing safe insertion into active systems.
• Includes IEEE 1149.1 JTAG boundary-scan testing for diagnostic verification.

Applications

• High-speed digital logic integration
• PCI bus interface designs
• State machine implementations
• Data path processing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required speed grade and temperature rating. Ensure compliance with export regulations such as ITAR or EAR if applicable to your region. Request official datasheets and RoHS documentation prior to finalizing acquisition.

Selection Notes

Select this model when a 208-pin surface-mount solution with 24,000 system gates is required. The -2 speed grade provides approximately 25% faster performance than the standard variant. Verify that the PQFP package dimensions fit the target PCB layout constraints. Ensure the design utilizes the available 175 user I/Os effectively within the specified voltage ranges.

Part Context

This component belongs to the Actel SX-A FPGA family, which was acquired by Microchip Technology. The SX-A series is characterized by its high-performance antifuse architecture and deterministic timing. It serves as a single-chip solution for low-power, high-speed applications previously requiring multiple CPLDs or gate arrays.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Microchip Technology directly for current equivalent recommendations or migration paths from discontinued speed grades.
