A54SX16P-PQG208I

The A54SX16P-PQG208I is a nonvolatile SX-A family FPGA from Microchip Technology designed for industrial embedded applications. It delivers a mix of programmable logic, abundant I/O and robust system features in a 208-pin package for applications that require flexible logic integration and mixed-voltage I/O support.

This device targets designs that need deterministic timing, in-system verification and a compact, surface-mount form factor while supporting a 3.0 V to 5.5 V supply range and industrial temperature operation.

Key Features

• Logic Capacity — Approximately 24,000 system gates implemented as 1,452 logic elements for implementing combinatorial and registered logic.
• I/O — 175 user-programmable I/O pins with configurable support for multiple voltage standards and up to 5 V input tolerance.
• Package and Mounting — 208-pin BFQFP package (supplier package: 208‑PQFP 28×28) optimized for surface-mount PCB assembly.
• Voltage and Temperature — Wide supply range from 3.0 V to 5.5 V and industrial-grade operation from −40 °C to +85 °C.
• Performance (Family) — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family-level specification).
• Nonvolatile Single-Chip Solution — On-chip nonvolatile configuration eliminates the need for external configuration memory (family feature).
• Configurable I/O and Drive Control — Configurable I/O support for standards such as 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, plus individual output slew-rate control and configurable weak pull-up/pull-down on power-up (family features).
• System and Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and unique in-system diagnostic/verification support (family features).
• Security — Actel Secure Programming Technology with FuseLock™ to protect bitstream confidentiality (family feature).
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Control — Implement motor control logic, protocol handling or I/O aggregation where industrial temperature range (−40 °C to +85 °C) and numerous I/Os are required.
• Interface Bridging — Use the configurable multi-voltage I/O to bridge or adapt between 5 V and lower-voltage logic domains in mixed-voltage systems.
• Embedded System Glue Logic — Replace discrete logic and CPLDs with integrated, reprogrammable logic blocks to simplify boards and reduce component count.
• In-System Diagnostics and Test — Leverage JTAG boundary-scan and built-in diagnostic capabilities for manufacturing test and field verification.

Unique Advantages

• Integrated Nonvolatile Configuration: Eliminates external configuration memory for simpler BOM and predictable power-up behavior.
• Wide Supply Flexibility: 3.0 V to 5.5 V operation enables use across legacy 5 V and modern 3.3 V systems without additional level shifters.
• Industrial Temperature Rating: Rated for −40 °C to +85 °C, supporting deployment in temperature-challenging environments.
• High I/O Count: 175 user I/Os provide extensive external connectivity for sensors, buses and peripherals in a single device.
• Security and Test Features: On-chip security (FuseLock) and IEEE 1149.1 boundary-scan support improve IP protection and testability.
• Compact Surface-Mount Package: 208-pin BFQFP/PQFP format allows high-density board integration while keeping routing manageable.
