A54SX16P-2PQ208I

Overview

The A54SX16P-2PQ208I is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It provides 24,000 system gates and 1,452 configurable logic blocks within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates at an industrial temperature range of -40°C to +85°C and supports mixed-voltage I/O standards including 3.3V and 5V PCI, TTL, LVTTL, and LVCMOS2. It features hot-swap compliant I/Os, boundary-scan testing via IEEE 1149.1 JTAG, and up to 175 user-programmable I/O pins.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems
• Support for mixed-voltage operation with 5V input tolerance and drive strength
• Integrated Boundary-Scan Testing compliant with IEEE Standard 1149.1

Applications

• Industrial control systems requiring deterministic timing and high reliability
• Telecommunications infrastructure utilizing 66 MHz PCI compliance
• Embedded applications needing secure, single-chip FPGA solutions

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm that the specific ordering suffix matches the required speed grade (-2), package type (PQFP), and industrial temperature rating. Request original manufacturer documentation to ensure compliance with RoHS directives and verify the absence of counterfeit markings.

Selection Notes

Select this model when design requirements include 24,000 system gates and a 208-pin surface-mount interface. The -2 speed grade offers approximately 25% faster performance than standard variants. Ensure the application environment falls within the specified -40°C to +85°C operating range and utilizes compatible voltage levels for the PQFP package constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a cost-effective alternative to complex programmable logic devices. The A54SX16A variant specifically targets designs requiring moderate logic density with robust I/O flexibility.

Replacement Considerations

Direct replacements within the same package and pinout include other A54SX16A speed grades such as A54SX16P-PQ208I or A54SX16P-1PQ208I, provided timing requirements are met. Cross-family migration to newer Microchip ProASIC or PolarFire series requires schematic redesign due to architectural differences.
