A54SX08A-1PQ208I

Overview

The A54SX08A-1PQ208I is an industrial-grade antifuse FPGA from the Actel SX-A family, housed in a 208-pin Plastic Quad Flat Pack (PQFP). It provides 12,000 system gates and supports up to 130 user I/Os. The device operates on a 0.22 μm / 0.25 μm CMOS process with mixed-voltage I/O capabilities supporting 2.5 V, 3.3 V, and 5 V levels. It features three global clock networks and offers hot-swap compliance for most I/O standards. The -1 speed grade indicates performance approximately 15% faster than the standard speed variant.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Supports mixed-voltage operation with 5 V input tolerance and drive strength across 2.5 V, 3.3 V, and 5 V I/O banks.
• Hot-swap compliant I/Os allow insertion into active systems without degrading host reliability or requiring specific power sequencing.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing with dedicated or flexible JTAG pin configurations.

Applications

• Industrial control systems requiring deterministic timing and nonvolatile configuration.
• Hot-swappable hardware modules where system uptime and safe insertion are critical.
• Mixed-voltage interface designs connecting 5 V legacy components with lower voltage logic.
• Secure embedded applications utilizing FuseLock technology to prevent reverse engineering.

Procurement Notes

Verify the ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) and 'PQ208' specifies the Plastic Quad Flat Pack package. Confirm the '-1' speed grade matches design timing requirements relative to standard speed parts. Ensure the source document explicitly lists this part number as available, noting that older Actel/Microchip products may have limited production runs or require verification of current manufacturing status through official channels.

Selection Notes

Select this device when a nonvolatile FPGA architecture is preferred over volatile SRAM-based FPGAs to eliminate configuration boot times and external flash memory. The SX-A family's sea-of-modules architecture allows for 100% pin locking and full resource utilization. Consider the -1 speed grade if slightly higher performance is needed compared to the standard grade, while ensuring the 208-pin PQFP package fits the PCB footprint constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for high security and low power consumption.
