A54SX16P-1PQ208

Overview

The A54SX16P-1PQ208 is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports up to 350 MHz internal performance with a maximum user I/O count of 175 in its 208-pin Plastic Quad Flat Pack (PQFP) package. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap compliant I/Os allowing power-up/down in any order without sequencing requirements or damage to the host system.
• Features deterministic timing through patented DirectConnect and FastConnect routing resources that minimize signal propagation delays.

Applications

• High-performance digital logic integration replacing complex CPLDs
• Systems requiring secure design protection against reverse engineering
• Industrial control applications necessitating wide operating temperature ranges

Procurement Notes

Verify component authenticity by checking markings against official datasheet specifications. Confirm the specific speed grade suffix '1' indicates approximately 15% faster performance than standard speed. Ensure the PQFP-208 package matches your PCB footprint requirements before procurement.

Selection Notes

Select this model when 24,000 system gates are required with industrial temperature stability. The '1' suffix denotes a specific speed grade offering higher frequency performance than the standard variant. Verify that the 208-pin PQFP package dimensions fit the available board space constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for nonvolatile configuration. The SX-A series is designed for low-power, high-performance applications, offering a cost-effective alternative to gate arrays while providing robust security features inherent to the antifuse architecture.

Replacement Considerations

Compatible alternatives within the same family include the A54SX16A-PQ208I (standard speed) or the A54SX16A-2PQ208I (higher speed). Ensure the replacement maintains the PQFP-208 package and Industrial temperature grade if environmental conditions require it.

FAQ

What is the difference between the A54SX16P-1PQ208 and the standard speed version?

The '-1' suffix indicates a speed grade that is approximately 15% faster than the standard speed version, allowing for higher clock frequencies and reduced logic delays.

Does the A54SX16P-1PQ208 support mixed-voltage I/O operation?

Yes, the device supports 2.5 V, 3.3 V, and 5 V mixed-voltage operation with 5 V input tolerance and drive strength, allowing flexible interfacing with various system components.

How does the device handle unused JTAG pins?

In Flexible mode, unused TDI, TCK, and TDO pins can function as regular user I/Os. In Dedicated mode, they are reserved for Boundary-Scan Testing and cannot be used as general-purpose I/Os.
