A54SX32A-FTQG100

The A54SX32A-FTQG100 is a member of the SX-A family of nonvolatile, single-chip FPGAs from Microchip Technology. It provides a programmable logic platform with 48,000 system gates and 2,880 logic elements in a compact 100-pin LQFP surface-mount package.

Designed for commercial applications, this device offers flexible I/O, mixed-voltage operation and family-level performance characteristics such as up to 250 MHz system performance and up to 350 MHz internal performance, making it suitable for a range of embedded control and interface tasks.

Key Features

• Programmable Logic: 2,880 logic elements (combinatorial cells) delivering 48,000 system gates for implementing custom logic and control functions.
• User I/O: 81 user-programmable I/O pins in the 100-LQFP package with configurable I/O support for multiple signaling levels as provided by the SX-A family.
• Supply and Mixed-Voltage Support: Operates from 2.25 V to 5.25 V and, as part of the SX-A family, supports mixed 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance and 5 V drive strength.
• Package and Mounting: 100-pin LQFP (surface mount) in a 14 mm × 14 mm form factor suitable for compact commercial designs.
• Commercial Temperature Grade: Specified for 0 °C to +70 °C operation for commercial applications.
• Family-Level Performance and Reliability Features: SX-A family features include nonvolatile single-chip configuration, hot-swap compliant I/Os, power-up/power-down friendly operation without sequencing, 66 MHz PCI compliance, boundary-scan (JTAG) testing, and security features such as Actel FuseLock™ programming technology.

Typical Applications

• Embedded Control Systems: Implement timing-critical glue logic and control functions using the device’s deterministic timing and abundant logic elements.
• Interface Bridging and I/O Expansion: Use the 81 configurable I/Os and mixed-voltage capability to bridge or translate between differing voltage domains and peripheral interfaces.
• PCI-Based and Legacy Bus Systems: Leverage SX-A family 66 MHz PCI compliance for integration in systems requiring PCI interfacing.
• In-System Diagnostics and Verification: Utilize the SX-A family’s in-system diagnostic features for build-time and field verification workflows.

Unique Advantages

• Nonvolatile, Single-Chip Solution: Eliminates the need for external configuration memory, simplifying board design and reducing BOM count.
• Wide Supply Range with Mixed-Voltage Support: 2.25 V–5.25 V supply range and family-level mixed-voltage operation enable flexible integration with 2.5 V, 3.3 V and 5 V systems.
• Compact, Surface-Mount Packaging: 100-LQFP package offers a compact footprint for space-constrained commercial designs.
• Design Security and Testability: Built-in programming security and IEEE 1149.1 boundary-scan support help protect IP and simplify board-level testing.
• Hot-Swap and Power-Friendly I/Os: I/Os designed for hot-swap and power-up/power-down friendliness reduce system risk during insertion and power sequencing.
